00:42.41 ``Erik free?
00:42.51 brlcad yup
00:43.04 ``Erik aight... they're all on the webpage and it's fast
00:43.05 brlcad most of the podcasts are free
00:43.26 brlcad yep, but clicking the *subscribe* is pretty darn convenient
00:43.33 ``Erik aight *shrug* :D
00:43.35 brlcad it'll automatically send me the new ones
00:43.40 ``Erik swank
00:43.52 ``Erik I might need to do that, heh
00:44.18 brlcad these video podcasts are getting addictive
00:44.27 ``Erik I have a bookmark folder of "daily urls" that I click "open all" on every day
00:45.08 brlcad getting daily nbc news, daily italian lesson, npr fresh air, strongbad, thistlepod, and a few others now
00:45.12 ``Erik freshmeat, slashdot, linuxgames, happypenguin, opengl.org, gamasutra, ibm's dev page, my comic page, zefrank, bash.org/?latest, qdb.us/?latest, ...
00:45.50 brlcad yeah, most of those are either on my rss list or are visited when I get the chance
00:45.55 ``Erik (the comic page crawls 20 or so webcomics and dumps the actual comic from each in a single big unified page)
00:46.04 brlcad i've seen/used your comic page
00:46.12 ``Erik ah, heh :)
00:46.13 brlcad i try to avoid comics these days
00:46.23 brlcad too many, too much time :)
00:46.24 ``Erik I have a v2 almost done, just some bughunting I think
00:46.50 ``Erik it has the notion of user and comic state, so if you've already seen the image, it won't show it again
00:47.29 ``Erik (and if you miss a day, it shows you all teh ones you haven't seen)
02:08.23 louipc hehe strongbad
02:08.51 louipc I wonder if there's a daily finnish lesson podcast

06:38.36 brlcad good stuff
06:57.17 Maloeran A stupid question ; does anyone have a term to refer to the entities of a processing network, may they technically be clients, servers, masters or slaves?
06:58.35 Maloeran Just trying to get proper terms for the API, "nodes" and "links" are already internally used for other concepts
06:59.50 brlcad processing node is what first comes to mind
07:00.52 brlcad might get away with peers if they are also peers
07:00.55 Maloeran Right. I'm trying to avoid confusion on internal terms
07:01.28 Maloeran "Peers" wouldn't be too appropriate, it's more master/slave based
07:02.30 Maloeran Thanks, I'll use "Node" in the API and try to avoid confusion within the source

07:44.08 brlcad dammit.. per-program cppflags wasn't added until automake 1.7
08:18.08 CIA-5 BRL-CAD: 03brlcad * 10brlcad/src/canon/canonize.c: need stdlib.h for exit(), quell warning
08:24.50 CIA-5 BRL-CAD: 03brlcad * 10brlcad/src/libfb/if_ogl.c:
08:24.50 CIA-5 BRL-CAD: rename ogl_open, ogl_close, and ogl_choose_visual to have an fb_ prefix to avoid
08:24.50 CIA-5 BRL-CAD: namespace collisions with libdm. this should probably be done more
08:24.51 CIA-5 BRL-CAD: comprehensively, but gets past the linking error du jour. declare funcs one per
08:24.51 CIA-5 BRL-CAD: line while we're in here.
08:27.25 brlcad what is this ..
08:27.32 brlcad sleep .. you speak of
08:27.47 Maloeran It's very relaxing, you should try it sometimes
08:27.56 brlcad sounds like devil talk
08:28.03 brlcad keep your voodoo magic to yourself
08:29.58 brlcad hm. i wish there were a 24 hour gym nearby.. i could really go for a workout right about now
08:30.20 Maloeran Running outside in the snow won't do the trick? It works for me
08:30.46 brlcad there's not much snow out, but plenty of ice I"m sure
08:31.01 Maloeran Ah yes, that's less pleasant
08:31.18 brlcad rather dark to see it too this far out
08:32.57 brlcad plus, my knees and quads are already sore from yesterday, I'd rather do some heavy lifts and something less pounding on the knees .. followed by a nice dip in a hot tub or sauna..
08:33.00 brlcad mmMMMmmmm
08:33.37 Maloeran So I'm guessing you don't have to be at work at 7h30 tomorrow, right? :)
08:36.00 *** join/#brlcad clock_ (n=clock@zux221-122-143.adsl.green.ch)
08:36.50 brlcad I don't, but I think I will go in anyways .. should be pleasant enough to get some work done
08:36.52 CIA-5 BRL-CAD: 03brlcad * 10brlcad/ (12 files in 10 dirs):
08:36.52 CIA-5 BRL-CAD: remove the png headers from our include directory. png_cppflags are now
08:36.52 CIA-5 BRL-CAD: provided by configure and appropriately set to src/other/libpng if we're not
08:36.52 CIA-5 BRL-CAD: using a system libpng. this should help to avoid header conflicts aside from
08:36.52 CIA-5 BRL-CAD: just unnecessarily duplicating 3rd party headers. use the new png_cppflags as
08:36.55 CIA-5 BRL-CAD: appropriate, though have to add it to _CFLAGS since per target _CPPFLAGS support
08:36.57 CIA-5 BRL-CAD: wasn't added until automake 1.7 (and brl-cad allows anything 1.6.0+).
08:37.12 brlcad maybe keep hacking here until the gym opens at 5, then in to work
08:37.58 Maloeran Impressive. I'm barely able to write code after being awake a mere 18 hours
08:39.01 brlcad varies for me, sometimes good for 20, sometimes 40 .. depends what I'm doing during my circadian low
08:40.17 brlcad my schedule rotated a few times last week from a couple all-nighters, so I don't think I'll hit a low until about 8am right now
08:40.47 brlcad so makes for an easy 40 as I'll be energized after the workout, and busy
08:43.28 Maloeran Eheh, nice. My circadian cycle used to be completely messed up, days of 30 hours, for years... I really made an effort to adopt a normal daily cycle when the contract began
08:44.32 clock_ I went sleeping yesterday at midnight instead of the recently more usual 22.40 and my rhythm is going to be screwed up from that for about the next week ;-)
08:48.59 CIA-5 BRL-CAD: 03brlcad * 10brlcad/src/ (91 files in 31 dirs):
08:48.59 CIA-5 BRL-CAD: convert all of the lingering getopt calls to bu_getopt (as well as the related
08:48.59 CIA-5 BRL-CAD: getopt globals optind, opterr, optarg) -- libbu's getopt has the benefit of
08:48.59 CIA-5 BRL-CAD: being re-entrant and is portable to environments where getopt() may not be
08:48.59 CIA-5 BRL-CAD: available.
10:03.47 CIA-5 BRL-CAD: 03brlcad * 10brlcad/configure.ac:
10:03.47 CIA-5 BRL-CAD: check for -lstdc++ properly like any other library. add conditionals around the
10:03.47 CIA-5 BRL-CAD: openNURBS checks so if it's disabled, the checks are not performed. rephrase
10:03.48 CIA-5 BRL-CAD: the availability summary (we're not necessarily linking them, they're just
10:03.48 CIA-5 BRL-CAD: available)
14:49.42 bjorkBSD you're aging!
14:49.51 ``Erik brlcad: would it be so horrible to bump the required automake to 1.7? 99.9% of the consumers will just use what package with it when you do a "make dist"...
14:50.41 ``Erik no, my employer does not understand the notion of 'first 40' or 'flex time'

15:30.52 Maloeran Woohoo, SURVICE understood how direct deposit to canadian banks works. Time to buy some hardware
15:43.18 bjorkBSD survice sells hardwar?
15:43.20 bjorkBSD e
15:43.40 dtidrow they sent money so that he can buy some
15:44.33 bjorkBSD can anyone receive money to buy hardware?
15:45.06 dtidrow heh - would be nice, wouldn't it? ;-)
15:46.00 dtidrow IIRC, they've got some sort of consulting arrangement going
15:46.10 bjorkBSD they buy him hardware and he says 'woohoo'
15:46.19 bjorkBSD hmmm. i'd like such a gig too.
15:58.33 brlcad ``Erik: yes it would be
15:59.26 brlcad at least right now, with the main dev platform still shipping 1.6.3
16:04.57 Maloeran Still awake, Sean? :)
16:06.08 brlcad yeap
16:06.35 brlcad didn't make it to the gym, though ..
16:06.38 bjorkBSD say, did you develop the industry diagram?
16:06.41 bjorkBSD ... it's my wall paper :D
16:06.43 brlcad mebbie later
16:06.53 brlcad bjorkBSD: heh, neat
16:08.20 bjorkBSD yeah.
16:09.04 bjorkBSD i put away my brl tutorials until i saw that cray lecture mentioning brl :D
16:10.06 brlcad =)
16:10.34 bjorkBSD eh. i was gonna use rhino.
16:10.55 bjorkBSD but i found religion so i'll stick to this.
16:11.13 brlcad heh
16:11.39 brlcad rhino's pretty nice, for some purposes in particular
16:11.56 brlcad entirely limited in other ways, but nice for their market
16:11.59 bjorkBSD but brl is functionally equivalent so i'm not gonna worry about it too much.
16:14.12 bjorkBSD how come the mged user manual isn't mentioned in the docs ... or am i not seeing what's infront of me (as usual) ?
16:14.35 brlcad bjorkBSD: not mentioned in which docs?
16:14.37 bjorkBSD yeah it's in .ps and it starts from the bibliography but it's pretty damned good!
16:14.48 bjorkBSD the brl docs... i didn't see it on the sourceforge site.
16:15.49 brlcad ahh, mostly because the ones that are up there were converted to html, and nobody got around to doing that for the other volumes
16:16.05 bjorkBSD oh.
16:17.01 brlcad most of the website stuff is rather "half-baked" in need of overhaul attention
16:17.11 bjorkBSD hrmmm
16:17.33 brlcad with the exception of maybe the rest of the sf project pages
16:17.49 bjorkBSD okay.
16:17.51 brlcad but brlcad.org, for example, needs to be redone
16:17.58 brlcad what's up there now was literally the bare minimum
16:18.56 brlcad bjorkBSD: if you are interested in working on it, you're more than welcome ;)
16:19.03 bjorkBSD <PROTECTED>
16:19.20 bjorkBSD i use vi and ed so minimalism is my middle name.
16:19.27 brlcad hah
16:19.38 bjorkBSD however, a user manual/info thingy is part of the product
16:19.51 bjorkBSD and it really helps make it more use-able.
16:20.03 bjorkBSD so ... i'd like to take a stab at it.
16:20.15 bjorkBSD don't expect fancy flying gifs though :-S
16:20.22 brlcad i'd really at least like to get those documents into CVS, but that's a chore
16:20.24 bjorkBSD or umm flash-ey bits and what not.
16:21.05 bjorkBSD why the hell not? :D
16:21.08 brlcad just fancy flashy flying pngs instead? :)
16:21.11 bjorkBSD hahahha
16:21.57 brlcad the tutorial series is fairly straightforward .. mainly converting them all to docbook is just grunt work
16:22.23 bjorkBSD never used docbook. i'll find out.
16:22.30 brlcad the hard question is whether things like the industry diagram can be brought in as anything other than an image
16:23.34 bjorkBSD it's a nice wallpaper i tell you.
16:23.52 brlcad there's no good/common standard format where I could actually get the diagram back to the tools used to create it
16:24.05 bjorkBSD what'd you use?
16:24.26 brlcad that was mostly done in indesign
16:25.34 bjorkBSD hmm
16:25.41 brlcad rather tufteish diagram, I should send it to him to see if he'd comment
16:25.51 bjorkBSD hehehehe
16:26.07 brlcad it has something like 7 dimensions of data
16:27.10 bjorkBSD well, my car's not co-operating with me and it's too cold to go play outside so i should do something.
16:27.21 bjorkBSD i might uncover more tutorials to push me along :)
16:28.28 bjorkBSD the one i'm using is a little long in the tooth on just a chapter or two which might fit neatly in an appendix.
16:29.12 ``Erik brlcad: "main dev platform"? both fink and macports have newer automakes, as does fbsd... :D
16:29.49 brlcad ``Erik: your point being? neither of those are provided by default
16:30.01 ``Erik aight *shrug*
16:30.50 brlcad it's only a minor annoyance that have to use _CFLAGS instead of _CPPFLAGS .. hardly worth changing a fundamental version minimum
16:31.31 brlcad especially one that would make things a pita in general for the common use
16:32.33 ``Erik <-- has always taken the "it's a distributable, so I'll use whatever I have on my system" approach, very few people should be touching the Makefile.am's, and those that should touch them probably have a more recent version or can get it and know what to do :)
16:32.46 ``Erik you're not in the building, are you? it's gettin' to be lunch time
16:33.06 brlcad nope, I ditched
16:33.19 bjorkBSD where do i sign, mr brl?
16:33.29 ``Erik dave is disturbingly eager to check out the o club O.o
16:33.29 bjorkBSD *signup*
16:33.37 brlcad ``Erik: even for just myself.. it would make my daily use a pita as I'd have to change all the macs I work with
16:34.02 brlcad bjorkBSD: right here ;)
16:34.14 ``Erik ok... all the macs I work with have 1.10 from macports, it's a fundamental to my operation as putting my dock on the side and changing to graphice :)
16:34.20 ``Erik graphite
16:34.20 bjorkBSD -> bjork is a GODDESS :x
16:34.22 bjorkBSD there. done.
16:34.46 brlcad that's just because you're a bsd zealot even on the mac ;)
16:35.18 brlcad bjorkBSD: hehe
16:35.52 ``Erik I d'no if I'd say "zealot".. I do have solid expectations of how machines should operate (they should work, be efficient, and let me get my job done with minimal fuss) that drives me towards the bsd's with a certain package load
16:36.09 brlcad yeah yeah, it's religion ;)
16:36.38 ``Erik heh, at least it's the right one ;>
16:36.49 brlcad I appreciate it to, but I also like things working without any effort on my part to "set them up"
16:37.08 brlcad when that can be done without a setup cost, sweet
16:37.30 brlcad when it can't, se la vie .. another day
16:38.08 ``Erik out of the box, a mac needs serious help... gotta get X on it, gotta get Xcode, gotta make some symlinks, ...
16:38.29 ``Erik I should stupid one of my macs back to vanilla for testing, I suppose :)
16:38.43 bjorkBSD a script!
16:38.52 bjorkBSD a setup script! that's what your mac-y needs
16:39.07 brlcad technically you don't "gotta get X on it" nor any symlinks, and a compiler is there by default
16:39.25 ``Erik hm, all 5 of them are already 'correct', why should I make a script? :D
16:40.00 bjorkBSD hehehe to make the 6th one easier to setup.
16:40.05 ``Erik hum, I thought out of the box, it didn't have gcc... (unless you use the developer package some versions came with)
16:41.28 brlcad I've heard of some getting a system that really had no compiler installed, but I've yet to see one that didn't and those claiming it didn't weren't entirely reputable
16:42.31 brlcad might have just been named something different for that matter, they support the "posix compiler" interface too (cc, c89, c90, etc)
16:44.29 Maloeran OSX is the "main dev platform"? Gah!
16:44.46 bjorkBSD the plot thickens
16:44.52 bjorkBSD Maloeran's view dims.
16:45.01 brlcad in the end, it still comes down to usability -- if some random user downloads the package and attempts to compile -- it's far easier to tell them to install the dev tools (and even X11) than macports followed by a set of command line things they have to run
16:46.17 brlcad Maloeran: philosophy is to run anywhere and everywhere .. "main dev platform" is an extension of where most of the development occurs, not any conscious decision to support any system over any other
16:46.52 brlcad if there were active windows devs or linux devs that were out-contributing, that would easily change
16:47.12 Maloeran From my limited experience so far, OSX seems a very poor platform performance-wise
16:48.18 brlcad a curious statement, really, though only a tiny fraction of the entire equation
16:49.33 ``Erik and, yeah, if your code abuses syscalls and you tune it so the abuse is acceptable on one os but not others, the other os's will look poor. Code better. :D
16:50.10 Maloeran Erik, test that raytracing benchmark on OSX, you'll see the same issues
16:51.17 ``Erik actually, I did with librt, and I didn't see that issue... the mac screamed... not as hard as the opterons, but it stomped the ia32 :)
16:51.56 Maloeran I now have a complete memory manager sitting on top of malloc(), but I would be eager to point out that it provides no benefit on Linux
16:53.07 bjorkBSD hmmm maybe i should dust off my indigo2 ;)
16:53.09 ``Erik (in fact, of all the cpu's and os's I tested, the g5/osX was the #3 spot in performance, the top two being opterons running fbsd and linux. Absolute worst was ia32 (p4-xeon) running linux)
16:53.16 bjorkBSD oh it still lacks a monitor.
16:53.23 bjorkBSD (to do... splurge on monitor)
16:53.34 brlcad bjorkBSD: heh
16:53.41 brlcad splurge
16:54.07 bjorkBSD yeah. after i develop my inventions in brlcad and sell them, of course :D
16:54.14 brlcad cool
16:54.33 Maloeran Erik, I guess they are less abusive in large memory allocation/freeing than my graph preparation code
16:54.47 Maloeran Even though it's all dynamically allocated
16:55.26 ``Erik you should invent and patent a business model for coping with the patent system :D
16:55.42 brlcad Maloeran: I actually wrote/ran a malloc analysis tool a few years ago whilest investigating a problem with malloc on 10.2 -- ran the tool across versions of the OS, ran on different hardware, different OSs
16:55.50 Maloeran "Patent on how to circumvent patents"
16:56.12 bjorkBSD you're patenting google.com/patents? :P
16:56.50 brlcad OS X 10.3 and 10.4's malloc performance is actually rather decent in comparison, it was amazingly better than everything else for some allocation sizes, or on par at others
16:57.03 brlcad a lot of variability in the lower allocation size ranges
16:57.06 ``Erik still got the data handy? and did you just do malloc and free, or did you do calloc and realloc, as well? (realloc tends to be one of the places where abuse really shows the dfiference between dlmalloc and phkmalloc)
16:57.57 Maloeran Ah... I don't know the details, but I know that my original graph preparation code would make OSX spend 90% of it's time in "syscalls", due to its aggressive freeing and zero'ing of pages
16:58.01 brlcad i ran calloc/realloc at the time and didn't notice really any relative difference on the first few tests, so in the interest of time stopped
16:58.30 Maloeran Code than ran in 10 seconds on Linux was taking several minutes on Erik's OSX box, I could hardly believe it
16:58.30 brlcad ``Erik: of course, I never get rid of any data ;)
16:59.35 ``Erik phkmalloc guarantees contiguous wire memory, so if it cannot cleanly grow the memory, it allocates a new area and copies the data, then frees the old one... dlmalloc dicks with the mmu lsu and just lives with insanely fragmented memory
16:59.59 Maloeran Insanely fragment memory is not a problem
17:00.21 Maloeran Caching and prefetching work in the process address space, not the translated addresses
17:00.37 ``Erik that depends...
17:00.54 Maloeran And anyway, realloc() was not the issue, I don't think there's any of that in the prep
17:01.17 ``Erik if y ou have something like hotswap domains where you can remove physical memory from a live machine, fragmented memory makes the release code much more complicated (therefore bug prone)
17:01.40 ``Erik the ugly and bad of fragmented memory is there, but it's the os's job to cover it up *shrug*
17:02.21 Maloeran Sacrificing performance because it's "more bug prone" is not a good argument for me :)
17:02.48 ``Erik adrt's initial file reader was something like read a page, realloc, read a page, ... it was ok on linux, but crawled on bsd :)
17:03.05 Maloeran Yes, it still does that to collect triangles
17:11.39 bjorkBSD hmm.
17:11.48 bjorkBSD i have an idea.
17:11.53 CIA-5 BRL-CAD: 03erikgreenwald * 10brlcad/src/adrt/ (14 files in 7 dirs): include bu.h and link libbu for bu_getopt

21:30.37 pcman hello
21:32.12 pcman can somebody help me to see if the BRL-CAD is a right choise for me. many thanks
21:34.18 brlcad pcman: howdy
21:34.43 pcman hello brlcad
21:34.49 brlcad pcman: can you pinpoint your need on this diagram? http://ftp.brlcad.org/Industry_Diagram.png
21:35.01 brlcad that might help you see if it's even in the ballpark ;)
21:35.37 pcman I am developing application for CAD engineering
21:35.57 brlcad owhat sort?
21:36.04 brlcad s/ow/of w/
21:36.05 pcman more exatly steel detailing and fabrication software on windows
21:36.24 pcman 3d model => details
21:36.36 brlcad that's starting to get into the CAM realm, but continue..
21:36.54 pcman from 3d model I create 2d drawings
21:37.13 brlcad okay
21:37.18 pcman fabrication (assembly)
21:37.24 pcman and overview
21:37.43 pcman currently I use a brep solid modeler
21:38.13 brlcad okay
21:38.30 brlcad what sort of 2D drawings to you create?
21:38.42 brlcad raster/vector?
21:38.50 pcman vector
21:38.50 brlcad engineering diagrams?
21:38.58 pcman not
21:38.58 brlcad ala blueprints
21:39.14 pcman not diagams
21:40.16 pcman sorry I am not sure about the term
21:40.30 brlcad how do you currently use the brep solid modeler (which one?) .. you model something in 3d, output a vector diagram, and feed that to the steel detailing machine?
21:41.07 pcman I need to create vectorial 2d cut to a 3d model
21:41.31 pcman 3d isometry with hidden line removal
21:42.18 pcman the output must be vectorial (I further process it programmatically)
21:42.41 pcman for dimension symbols, hatch, etc
21:42.52 brlcad hm, brl-cad can generate the latter, but alas not in a vectorized format currently
21:43.00 brlcad example: http://brlcad.org/images/havoc_rtedge.png
21:43.15 pcman I saw this thanks
21:43.37 brlcad most of the image output is configurable, but it's certainly not vector format
21:43.39 pcman the of rtedge is always an image
21:43.45 pcman ?
21:43.55 brlcad it could be vector format, but it would require source modifications
21:44.00 brlcad yes, it is
21:44.30 pcman and I can have access pogamatically to it?
21:44.50 brlcad i played with some tools that generate a vector image from raster images, but they take a fair bit of hand tweaking to get a good vector rep
21:45.01 pcman I see
21:45.13 brlcad all of brl-cad source code is available (free, open source)
21:45.30 pcman currently I use amodeler (Autodesk)
21:45.58 pcman I saw this and seems to be a great application
21:46.42 pcman I wanted first to check if it's good for my needs and then to digg into the sourcecode
21:47.12 brlcad there is a lot of functionality under the hood, but with minimal investment in some aspects (e.g. user interface, usability, etc)
21:48.14 pcman yes. I can understand this. It's not a comercial application
21:48.14 brlcad there is an API on the entire geometry layer, so you could certainly use the geometric information in a given model and build up a vectorized 2D projection
21:48.48 pcman this is what I need
21:49.10 brlcad rtedge under it's current implementation basically shoots some sized grid of rays into the scene and queries the geometry types .. it then evaluates the ray results to determine where there are pixels that span a geometric edge
21:49.53 brlcad instead of building up a pixel map, you could build up vectorized outlines (as you do have knowledge of geometry types upon intersection) and use that instead
21:51.17 pcman I can find information on each geometry the ray hits?
21:51.28 brlcad yep, that's the easiest part ;)
21:51.50 brlcad that's basically what all of the rt* apps do
21:52.15 pcman I will study it. thanks
21:52.34 brlcad src/rt/viewedge.c contains the guts to rtedge in the source code
21:52.56 brlcad primitive geometry are all implemented in src/librt/g_*.c
21:53.08 pcman thank you very much.
21:53.11 brlcad *ideally*, to get what you need..
21:54.17 pcman all of these are under the LGPL licensed parts?
21:54.20 brlcad you'd probably modify the primitives to provide a projected 2D representation or even just a BREP form of themselves .. you'd then apply any CSG transformations to the BREP forms and project that onto 2D
21:54.42 brlcad all of BRL-CAD's code, even the binaries, are now LGPL
21:55.11 brlcad basically all LGPL and BSD code (the build system, benchmark suite, and some helper scripts are BSD licensed) now
21:55.33 brlcad that announcement is going to be made with the next 7.10 release next week
21:55.39 brlcad though the changes are already in CVS
21:55.52 pcman great
21:56.12 pcman regarding your last advice
21:56.29 brlcad documentation changes from a dual-licensed GPL/GFDL to a variant of the BSD license as well
21:57.15 brlcad the last advice is the more involved, but not intractable .. and something others would likely contribute to and help with
21:57.15 pcman BSD is ok for comercial apps?
21:57.34 brlcad heh, BSD is one of the least restrictive
21:58.07 brlcad all BSD basically says is that you can't claim authorship on the parts you didn't write, otherwise you can do pretty much *anything* with the code (even sell it)
21:58.53 brlcad doesn't even require return of modifications like the LGPL, though any mods would be appreciated
21:59.08 pcman great.
21:59.41 pcman If we will choose BRL-CAD we will contibute
22:00.45 brlcad glad to hear it
22:01.14 brlcad that's one of the great aspects of being open source -- if it doesn't do what you want, you're welcome to make the changes to get it doing what you need
22:01.52 pcman I have one more concern regarding model size
22:02.13 brlcad there's a couple decades and a couple hundred overall man-years of effort invested as it is, so you get a nice leg up from otherwise starting from scratch
22:03.07 brlcad BRL-CAD's support for large models actually exceeds most of the commercial packages -- predominantly limited by your construction approach and hardware specifications (how much memory do you have sort of limits)
22:03.31 pcman yes. especially I will never get the budget to invest several years in dev. without results
22:04.27 pcman I have around 300,000 solid objects (not complex whan comparing to mechanical)
22:05.11 brlcad when you say "solid objects" what do you mean? primitive euclidean geometry or are those "parts" in themselves or something else?
22:05.45 brlcad sounds like some simple "parts" if I'm reading you right
22:06.17 pcman I call an object for example the brep body representation of a steel beam (with cuts, holes...)
22:06.19 brlcad like nuts and bolts, hinges, latches, doors, etc
22:06.28 brlcad yeah, okay
22:06.28 pcman yes
22:07.22 pcman I don't know many things about CSG so I am wondering if it's good to model a building with it
22:08.00 brlcad it's definitely a different approach in general than you have with traditional BREP feature-based modeling
22:08.28 pcman maybe it's too accurate for me and I loose speed
22:08.51 brlcad speed is one of the benefits actually, and compactness of the representation
22:09.27 brlcad CSG with primitives is about an order of magnitude smaller than spline surfaced BREPs which in itself is about an order smaller than facetized BREP
22:09.53 brlcad the downside is really the modeling approach that it requires, it's more mathematically rigorous
22:11.10 brlcad both are solid modeling approaches, so you get the same guarantees on topology and valid representations .. but the modeling interface for how you go about associating things is radically different
22:12.03 brlcad as a modeling interface, brl-cad's mged modeler leaves much to be desired -- if you specifically need a solid modeling user tool, you'll probably still end up writing your own interface or at least customize mged for your purposes if you went with brl-cad
22:12.18 brlcad that's changing with new interfaces being developed, but we're not there yet
22:12.38 brlcad the underlying representation, and api for creating/manipulating geometry is where there's a main benefit
22:12.54 pcman this is OK in my case. I only want to use the modeler component.
22:13.32 pcman in fact replace the current moder
22:14.45 pcman currently I persist in the model only parameters and I create (and cache) facetized bodies for display and algortithms
22:15.47 pcman With CSG probably the approach should be different.
22:16.27 CIA-5 BRL-CAD: 03brlcad * 10brlcad/TODO:
22:16.27 CIA-5 BRL-CAD: the script to M-x indent-regions now already exists (indent.sh). just need to
22:16.27 CIA-5 BRL-CAD: run the script on various directories one at a time while making sure
22:16.27 CIA-5 BRL-CAD: indentation isn't confused by replicated braces in preprocessor wrappings
22:16.28 brlcad you could actually do something similar still
22:17.45 brlcad brl-cad has an 'intermediate modeler' interface called archer that sort of does something very similar -- it has a concept of storing models in implicit CSG form as well as parameterized to some known template type (e.g. this is a "tank" with a turret this long and this many wheels) .. with facetized versions stashed for opengl display
22:19.22 pcman interesting. It's different then mged? I thought it's only another GUI
22:20.41 brlcad it is mostly a different gui, wraps what's under mged's hood in different ways, stores things somewhat differently in the .g geometry files
22:21.27 brlcad mention it not as something to use (though you certainly can) but as an example of something that performs a somewhat similar task
22:22.41 pcman Thank you very much. I will study CSG and BRL-CAD and come back other day.
22:23.15 brlcad pcman: sounds good -- if you have any questions, I'm usually here as are several others that should be able to answer questions
22:23.35 brlcad the tutorials/guides on the website cover most of the basic approach and design limitations
22:23.44 pcman thank you very much.
22:24.11 pcman There is available sample code for windows?
22:24.22 ``Erik yeah, I'm pretty retarded when it comes to modelling, but those guides were 'nuff to get me able to test my code mods, heh
22:24.24 brlcad HACKING file in the source distribution if you're interested in becoming part of the actual dev team (it's an open dev environment)
22:24.59 brlcad pcman: most of brl-cad's code, sample or otherwise, works under windows
22:25.25 brlcad there's studio build files in misc/ .. two different projects with different purposes
22:25.32 brlcad example code spread throughout the package
22:25.53 brlcad simple intro on the website: http://brlcad.org/example_app.php
22:26.01 brlcad as well as doxygen docs on the website too
22:27.12 pcman thank you
22:27.38 ``Erik speaking of doxygen; adrt has some doxygen markup, but it's not getting on the webpage... is it ignored on purpose, or is something slipping through the cracks?
22:28.54 brlcad ``Erik: probably because there's no group for that code listed in misc/doxygen_structure to key on, nothing in misc/Doxyfile that says exclude it
22:29.35 brlcad some of the doxygen markup was just me or justin adding a standard header with a @file section
22:30.22 ``Erik there's some function info in there, too
22:30.35 ``Erik and structs *shrug*
22:31.10 brlcad still, probably just because there's no group for it in the doxygen_struture file
22:31.37 ``Erik and try to get some emacs fu, too... heh
22:33.10 brlcad emacs fu?
22:33.21 brlcad could it be possible?
22:33.25 brlcad is erik seeing the light??
22:33.36 dtidrow_work heh
22:34.10 ``Erik ... 'slime' interests me.
22:34.26 dtidrow_work ouch
22:34.51 ``Erik and I'm always willing to learn new things *shrug* I tried ten years ago, before I tried vi
22:35.32 ``Erik and it just struck me as being incredibly difficult to work with... vi was clean and efficient by comparison *shrug* :) maybe this time around, it'll be a little more interesting to me
22:37.28 brlcad yeah, like "calculus struck me as being incredibly difficult to work with... basic addition and subtraction was clean and efficient by comparison"
22:37.46 ``Erik heh, not exactly the same comparison :)
22:37.52 brlcad close :)
22:38.00 dtidrow_work heh
22:38.10 ``Erik I d'no, vim isn't exactly a slacker editor...
22:38.21 ``Erik now if I were saying 'pico' or 'nano', then yeah, you'd have a valid point...
22:38.22 ``Erik :D
22:38.31 dtidrow_work more gasoline on the vi/emacs flamewar.... :-)
22:38.33 brlcad never implied that.. heck you can build an entire computer out of a basic ALU ;)
22:38.54 ``Erik and if I started jabbering about needing a decent gui ide, I'd hope someone would smack some sense into me
22:39.16 dtidrow_work emacs - the original IDE :-)
22:39.27 dtidrow_work and windowing system...

22:40.55 Twingy twice the finger chopping fun!
22:41.00 Twingy :D
22:41.39 Twingy at least you didn't lose your middle finger
22:42.11 Twingy that little parts box is awesome
22:42.17 Twingy found it at lowes for $15
22:43.02 brlcad shouldn't that fuel resovoir be on the other side to balance it out? :)
22:43.04 Twingy triton charger along with banana to banana, banana to deans, deans to j-type, banana to alligator, and deans to dc all fit up top with the triton charger
22:43.06 ``Erik the field box isn't sufficient?
22:43.13 Twingy heck no
22:43.36 brlcad could use a new paint job
22:43.45 brlcad the Justin 2000
22:43.54 ``Erik 'fuel resevoir'? are we lookin' at the same pic?
22:43.58 Twingy I haven't put any decals in
22:44.05 Twingy I think brlcad went to goatse.cx
22:44.15 ``Erik mebbe lemonparty or hai2u
22:44.21 bjorkBSD heheh
22:44.35 brlcad whatever is got some sort of line into the engine on the left
22:44.44 ``Erik that's the muffler
22:44.54 brlcad so then that
22:45.03 Twingy that weighs like 50 grams
22:45.09 Twingy if that
22:45.20 brlcad it wasn't for practical/weight reasons.. visual asthetic balance :P
22:45.25 Twingy ah
22:45.27 Twingy pfft
22:45.28 ``Erik int he air, ya wouldn't notice
22:45.41 ``Erik if visual asthetic is important, get a ducted fan *shrug* :)
22:45.49 brlcad i would.. it'd annoy me all the way to the ground as I repeatedly crashed it by mistake
22:45.49 ``Erik aesthetic
22:46.02 Twingy so the front nose area can house all of the electronics for my rocket as a testing platform, this plane has about 1.3:1 lift to weight ratio
22:46.22 ``Erik those're .25's or .40's?
22:46.28 Twingy 0.25 FX's
22:46.38 Twingy FX == 18k rpm, regular == 15k rpm
22:46.43 ``Erik not the ones with bearings, though
22:46.48 Twingy 0.46 == 1.2 HP, (2) 0.25 FX = 1.85 HP
22:47.23 Twingy this will do 50-55 mph level
22:47.39 Twingy my last plane (the demon plane) did 40-45 mph level
22:47.42 ``Erik how heavy is the rocket electronics payload? would it be better to dump those at the cg?
22:47.51 Twingy tiny and light
22:47.55 Twingy 100 grams maybe
22:47.56 ``Erik or just run the battery further back?
22:48.08 ``Erik ok, like a watch battery? or a single AAA?
22:48.24 Twingy I have a nicad pack that consts of 4 AAA batteries @ 7.2V
22:48.55 ``Erik also; is the plane vibration going to be different from rocket vibration? remebering the x10 camera...
22:48.56 Twingy smaller than AAA's iirc
22:49.11 Twingy yep
22:49.21 Twingy that's not going to do anything
22:49.47 ``Erik <-- looks forward to hearing about the telementry data :D
22:50.09 Twingy haven't built the new circuit (or rocket) yet
22:50.28 Twingy this plane will likely get flown once or twice then get grounded while new rocket is under construction
22:51.37 ``Erik one of these days, I'll finish that ultrasport 40
22:51.49 bjorkBSD why don't you build something you can fly in?
22:52.31 ``Erik bjork: that'd be really expensive... not just in parts, but in certification as well...
22:52.32 Twingy it'd be alot cheaper to just buy a phillipino kid to start your plane for you
22:52.45 ``Erik heh
22:53.07 Twingy they used to be rampant on ebay...
22:53.54 Twingy "Look boss Zee plane boss, Zee plane!"
22:53.54 ``Erik looks like it quit snowing
22:54.25 ``Erik locked cage in the back of the cave? :)

22:54.45 bjorkBSD certification? parts?
22:54.54 bjorkBSD you don't need either for a paramotor or an ultralight!
22:55.09 Twingy bjorkBSD, you couldn't fly those here, it's too developed
22:55.16 bjorkBSD where's 'here'?
22:55.21 ``Erik ultralights have pretty strict guidelines on altitude, weight, horse power, etc...
22:55.29 ``Erik baltimore
22:55.44 bjorkBSD yeah it's still ME flying vs squinting at a fly
22:55.45 ``Erik in the city, the gang bangers would shoot at you... away from the city, the rednecks would shoot at you...
22:55.47 bjorkBSD ah.
22:55.51 bjorkBSD hehehe
22:55.57 bjorkBSD i live in f'vlle, AR
22:56.15 ``Erik I would've guessed kansas city
22:56.16 bjorkBSD there's plenny of country to go around.
22:56.16 Twingy so you'd have rednecks shooting at you
22:56.26 bjorkBSD no. worse. hill billys!
22:56.33 bjorkBSD 'cause you'll be close enough to their homes.
22:56.37 ``Erik <-- used to live in springfield, missoura
22:57.34 ``Erik hillbillies are amusing :)
22:57.51 bjorkBSD yeah. they go hun'n for 'coons a lot.
22:57.59 bjorkBSD and they're liable to miss every now and then.
22:58.21 dtidrow_work heh
22:58.29 Twingy once I get gerber junk in gcam I'll make the boards
22:58.42 ``Erik twingy: for your interesting stuff, are you using an OS (like centos or qnx or something), or coding on the metal?
22:59.28 Twingy I have alot of interesting stuff, is this work or home related?
22:59.32 bjorkBSD 'interesting stuff'?
23:00.39 ``Erik (also; sorry to poop on the party, but if I understand correct... tie_push() takes a blind pointer that you can associate to anything and retrieve in the hit function?)
23:00.43 ``Erik work... are you actually coding embedded stuff (other than pic) at home? heh :)
23:01.15 Twingy a pointer to an array of pointers with a stride, the stride is the index to each pointer
23:01.22 Twingy typically 4 for 32-bit, 8 for 64-bit
23:01.54 ``Erik ok, is that per triangle, or is that a set associated with each triangle?
23:02.45 Twingy per triangle
23:02.56 Twingy feel tree to make a version more apropos to your application
23:03.04 ``Erik (or if you'd rather, where's the best place to start reading code to figure it out... I'm trying to build something akin to a greatly simplified librt partition list)
23:03.43 Twingy well, the one day you looked at libtie and said all this pointer junk is obfuscated I started adding comments galore
23:03.53 Twingy there should be almost 1:1 ratio between comments and code
23:04.09 ``Erik heh, I've already been changing conventions to make it feel more 'normal' to me... all the defined symbols got changed to uppercase, for example :) I'm operating under the notion that you don't give a rats ass anymore and rf will supercede it
23:04.38 ``Erik but I'm on the hook to prove that rf meets or misses the arbitrary 5x factor
23:04.44 Twingy it's there as an off the shelf 'thing' for you to take and twist/warp to your application
23:05.26 Twingy it's so small that it's really easy to go in and change the API all around
23:06.09 ``Erik ok, other stupid question; tie_work() processes just to the next hit? so to shoot all the way through, I'd have to keep calling it until it says it missed?
23:06.46 Twingy the hit callback you pass to tie_work continues to get called until it returns something non-NULL
23:06.56 ``Erik ah, 'k
23:07.00 Twingy very inefficient
23:07.09 ``Erik thanks :) hopefully you'll never hear about libtie again :D
23:07.19 Twingy but brl-cad style and what was suggested to be at the time of implementation
23:07.28 Twingy I don't mind either way
23:08.02 ``Erik (doncha hate when people in mgmt roles make technical decisions? they're never the right ones...)
23:08.03 Twingy I'm not into annexing myself from previous work, I just can't spend all of my time on it anymore
23:08.20 Twingy why do you think I left?
23:08.40 bjorkBSD the plane had to be built!
23:08.42 Twingy I'm honestly surprised more people haven't left yet
23:08.42 brlcad not enough cheese poofs
23:08.43 bjorkBSD j/k :P
23:09.11 Twingy I don't even like visiting that building any more cause of the anxiety it gives me
23:09.18 ``Erik heh
23:09.21 Twingy comparatively speaking
23:09.25 Twingy i didn't realize it until I left
23:09.31 Twingy and then a month later I came back
23:09.40 Twingy and just felt like a wave of stress
23:09.42 ``Erik you still need to give a subset of coworkers a tour of your new digs :D
23:09.55 bjorkBSD wait, is brlcad a secret project to turn aliens into fish? :(
23:09.59 Twingy wendy and I set something up before christmas, but she canceled it
23:10.10 ``Erik have ya talked to bob or paul lately? :D
23:10.16 Twingy I haven't heard anything since
23:10.51 Twingy lately? no, I probably won't interface with them ever again since we are in completely different lines of work now
23:11.12 ``Erik if the opportunity arose, I'd just go check it out, I'm done asking for wendys permission or input
23:11.58 Twingy well, I can tell you that if you stay there for another year things will probably be different, if you can't last that long then I'd suggest moving somewhere else
23:13.10 ``Erik heh, I keep getting requests from google and yahoo, and I'm half interested in doing the 'start a company' thing again. Of course, if I did that route, I'd find someone to play the sales/marketing/business side, I HATED that and was not good at it
23:13.43 ``Erik sucked 'nuff that I just quit once I hit the break-even point
23:13.50 ``Erik and went and got a 'real' job
23:14.53 Twingy the sig rascal is a nice plane too
23:15.03 Twingy if I had the money I might buy that
23:15.35 ``Erik that's a bigger one
23:15.59 Twingy http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXCXT9&P=0
23:16.02 ``Erik damn, $400
23:16.23 Twingy but that would fly so smooth
23:16.30 Twingy even in light winds
23:17.09 ``Erik nothing on the site about lift ratio
23:17.16 Twingy I will probably build my next plane on my cnc mill out of foam and balsa
23:17.28 Twingy the rascal would be a fun fly
23:17.30 ``Erik using someone elses plans? or a complete new work?
23:17.40 bjorkBSD you have a mil?
23:17.48 Twingy a continuation of something I started after I switched over
23:17.52 bjorkBSD *mill.
23:18.01 Twingy bjorkBSD, http://gcam.js.cx
23:18.08 louipc !! you have a CNC mill!?
23:18.15 louipc *envy*
23:18.16 ``Erik <-- always thought it'd be fun to design an r/c plane
23:18.44 bjorkBSD oh shit!
23:18.47 Twingy well, brian and I might design a larger cnc mill in our spare time using the taig
23:18.50 bjorkBSD i just got a <bleep>
23:18.52 bjorkBSD <PROTECTED>
23:19.04 bjorkBSD oh you have a TAIG! ohhh
23:19.11 bjorkBSD that's not terribly cheap.
23:19.13 louipc what's a taig?
23:19.19 bjorkBSD but you can buy it in bits.
23:19.31 bjorkBSD it's a micro-mill/lathe maker.
23:19.35 bjorkBSD do you have a lathe as well?
23:19.42 Twingy I had one, but I gave it away
23:19.56 Twingy I am going to buy a real one at some point
23:19.59 bjorkBSD funny. i don't see a lathe on my table :|
23:20.00 louipc ooh they look like conventional machines fitted with power feed har
23:20.02 Twingy I don't need one at the moment
23:20.08 bjorkBSD really?!
23:20.09 Twingy I have one at work
23:20.12 bjorkBSD oh!
23:20.16 louipc and I guess numeric control of course
23:20.17 bjorkBSD ah. but of course.
23:21.03 brlcad Twingy: seem to be doing well in Italy :)
23:21.06 Twingy best $1800 I ever spent
23:21.21 Twingy brlcad, yea, what's all that about?
23:21.36 brlcad dunno, but sounds like a road trip!
23:21.49 Twingy boat trip?
23:21.57 brlcad woot
23:22.02 Twingy or did you imply I should cnc mill a water proof car?
23:22.13 brlcad a submarine
23:22.15 louipc hehe
23:22.15 brlcad a yellow one
23:22.23 Twingy hrm, that might take a while :)
23:22.33 Twingy it'd be about 10,000 parts
23:22.33 ``Erik (someone hittin' the happy juice this evening?)
23:22.35 brlcad build it .. "in bits" :)
23:22.45 louipc you need a mini welder too
23:22.45 bjorkBSD damn. i want a workshop very very badly.
23:23.18 Twingy I haven't tried my new aluminum casting setup yet
23:23.19 ``Erik heh
23:23.24 bjorkBSD yeah i can buy one at harborfreight for relatively little.
23:23.31 Twingy I have some granite slabs and a jig with a metal trashcan filled with 250lbs of sand
23:23.31 bjorkBSD but their lathes/mills are POSs
23:23.52 bjorkBSD ah you're a metal worker and you have a forge and stuff?
23:24.04 Twingy if you call melting aluminum metal working
23:24.07 Twingy then yes
23:24.11 bjorkBSD heheh
23:24.24 bjorkBSD hmmm.
23:24.25 Twingy http://js.cx/~justin/images/alumiforge2/
23:24.40 Twingy http://js.cx/~justin/images/renesis_aluminum2.jpg
23:25.06 Twingy http://js.cx/~justin/images/renesis_block1.jpg
23:25.12 Twingy that's what I do with soda cans
23:25.14 brlcad that's a lot of cans
23:25.20 Twingy and 6061 scrap
23:25.26 brlcad ahh, cheated ;)
23:25.36 Twingy I add 1% zinc
23:25.50 bjorkBSD it sits on a table!
23:25.50 brlcad for that silky smooth feeling?
23:25.54 bjorkBSD i can have one in my kitchen :-?
23:26.14 Twingy I can sell those blocks for $15 - $20
23:26.26 brlcad heh, you're asking the guy that sets off rockets that are just a couple screws short of being a pipe bomb.. ;)
23:26.28 louipc you machined that whole block with that tiny cutter? haha
23:26.32 ``Erik what's the fuel cost to make one? :D
23:26.45 Twingy louipc, yep
23:26.51 ``Erik propane high output burner, right? so a tank is pretty cheap?
23:26.53 Twingy ``Erik, $3 in propane
23:27.04 ``Erik coo'
23:27.13 Twingy 1 tank does about 8 castings
23:27.22 louipc you need to get a facemill methinks
23:27.22 brlcad mm.. tanks
23:27.48 louipc that's pretty cool though
23:27.57 bjorkBSD so Twingy, have you built a tesla coil lately? :D
23:28.07 Twingy no, just a coil gun :)
23:28.16 bjorkBSD <PROTECTED>
23:28.28 bjorkBSD what made you wanna build a forge?
23:28.51 Twingy http://js.cx/~justin/tmp/
23:29.24 Twingy that was my first
23:29.52 Twingy that charging circuit was a kodak disposable camera
23:32.06 Twingy hehe
23:32.08 Twingy http://js.cx/~justin/tmp/rocket1.png
23:32.11 Twingy priceless
23:33.09 bjorkBSD what's nurbana?
23:33.14 brlcad heh
23:33.38 Twingy it's nothing more than a memory :)
23:35.10 brlcad it was the next "rhino", left to rot after lack of feed .. and then carved up for it's meat on the open market, right? ;)
23:35.41 Twingy that pretty much sums it up
23:35.44 bjorkBSD heheh.
23:35.51 bjorkBSD what's wrong with brlCad twingy?
23:35.59 bjorkBSD it's like rhino. only ... umm.
23:36.13 Twingy I didn't know about brl-cad in 1999
23:36.22 bjorkBSD that was a long long time ago.
23:36.31 ``Erik also; brl-cad isn't exactly rocking at nurbs...
23:36.39 brlcad nor was it as readily open to use like it is today
23:36.39 bjorkBSD no?
23:37.03 brlcad there's nurbs support, pretty extensive, but incomplete and slow
23:37.06 bjorkBSD hmm it still makes people flee in horror on first contact
23:37.21 brlcad that's a lot of the work going on this year.. to totally reimplement the nurbs support (hence all the opennurbs stuff)
23:37.44 brlcad yeah, mged is a major wart
23:38.04 brlcad one that can actually cure cancer, but a wart nonetheless
23:38.25 ``Erik thermonuclear masochism device?
23:39.31 dtidrow_work lol
23:44.26 Twingy I still vividly remember the day when Lisa announced that Wendy got the branch chief position and everyone frowned at once, haha
23:44.40 dtidrow_work heh
23:46.07 bjorkBSD damn
23:46.11 bjorkBSD how do i get out of jove? :(
23:46.17 bjorkBSD <PROTECTED>
23:46.18 brlcad hah
23:46.19 ``Erik heh
23:46.28 bjorkBSD i didn't even know it was here until you mentioned it.
23:46.28 ``Erik jove--, vi++
23:46.40 brlcad that's the "trick" .. they've been stuck in jove for 20+years ;)
23:47.06 brlcad try ctrl-x-c or ctrl-x ctrl-c
23:47.11 ``Erik (seriosuly, the "search for a real editor; is emacs found? no? build jove" shit is uncool) :D
23:47.35 dtidrow_work Twingy: some things you could build with that mill of yours: http://www.modelengineeringsoc.com/photo2.htm
23:47.41 Twingy if jove00, and vi++, then nano^=1 ?
23:48.03 Twingy yep
23:48.10 Twingy I have a stirling and a steam engine on my lifes todo list
23:48.24 ``Erik what kind of steam engine?
23:48.32 ``Erik ece reciprocal?
23:48.41 dtidrow_work I've been to their expo, back when it and I were both still in Michigan
23:48.42 bjorkBSD i want a machine shop :(
23:48.54 bjorkBSD impossible!
23:48.57 bjorkBSD are you talking about a kettle?
23:49.03 ``Erik teh sterling engine out of soda cans was cool
23:49.12 brlcad nope, it's a real steam engine.. a small one, but real
23:49.19 bjorkBSD wow! how'd you get it?
23:49.36 brlcad long time ago as a kid
23:49.45 brlcad hobby shop had one iirc
23:49.58 ``Erik functional steam engine...
23:50.22 dtidrow_work they run off compressed air, too
23:50.47 brlcad a little bit like this, but actually a little smaller and with front wheels too ;) http://www.modelengineeringsoc.com/01-20L.jpg
23:50.58 ``Erik anything with a pressure differential, actually
23:51.21 ``Erik steam involves a state change, so there's a huge pressure differential from a fairly minor temperature change
23:51.28 ``Erik weee, thermo
23:53.34 brlcad here we go: http://www.ministeam.com/acatalog/wid365big.jpg
23:53.43 brlcad i thought about making a cad model of that at one point
23:53.59 brlcad didn't want to take it apart though..
23:56.08 brlcad good stuff: http://www.toysteam.net/
23:56.08 brlcad heh, this would be cool to mill Twingy: http://www.neatstuff.net/space-robots/Steambot-ST-II.html
23:56.42 brlcad "please feed me water.. *mauuuuwww*"
23:58.15 ``Erik ah, a steam tractor, even
23:58.31 ``Erik the one I saw at the exchange was a stnading engine, not a tractor :) just a boiler and piston
23:58.54 brlcad they have one of those too
23:59.02 brlcad the locomotive is more interesting
23:59.43 ``Erik 8? hah
23:59.47 ``Erik might as well be using a single core
23:59.48 ``Erik :D
