irclog2html for #brlcad on 20070321

00:10.12 IriX64 got that shuttle dxf to go, pix is on my blog, note its not the acad shuttle, but a dxf is a dxf.
00:21.21 deltazap hmm?
00:28.24 louipc what wm do you use?
00:28.38 louipc or do you use linux?
00:34.43 brlcad there have been several suggestions/discussions about merging some of qcad's capabilities with brl-cad's
00:37.10 brlcad certainly doable, especially given how qcad just uses dxf for their format and we have a fairly comprehensive dxf importer and exporter
00:48.53 IriX64 http://www.pastebin.ca/404451
01:01.23 IriX64 is a release date actually set for 7-10? or is that a vaporeous thing still? :)
01:05.10 brlcad any day now, as soon as these builds stabilize
01:06.57 IriX64 are you *sure I can't have the database to stryker pix :) (ducking)

17:50.50 IriX64 http://www.pastebin.ca/405334 < this should fix that bug I inadvertantly put in (mea culpa)

18:22.09 brlcad off what?
18:22.38 IriX64 not sure what it should be
18:23.05 IriX64 err sorry
18:23.11 brlcad not sure what you're talking about
18:23.49 brlcad /dev/ogll and /dev/ogl are both valid if ogl support is enabled, but mean different things
18:24.12 IriX64 ty thought it should be one or the other
18:24.14 brlcad "ogl" is the device name, anything that follows are settings
18:24.27 brlcad there are a variety of possible settings (brlman libfb)
18:24.40 IriX64 thats what im missingf thanks
18:24.45 brlcad l is one of them, meaning "linger" .. i.e. don't close the window
18:25.06 brlcad same is seen with /dev/X and /dev/Xl
18:25.15 IriX64 got it
18:25.16 brlcad X is the device, l means keep the window open
18:25.26 IriX64 ill learn :)
18:25.30 brlcad there are others for using shared memory, single/double buffering, etc
18:25.39 IriX64 it is complex
18:25.47 brlcad not really, just flexible
18:26.06 IriX64 heh to you yes but im just starting out
18:30.11 IriX64 -msses ;)
19:31.26 Maloeran Do you guys know anything about the potential difficulties and risks of carrying a packed E-ATX computer case by plane?
19:31.35 Maloeran I assume it wouldn't be adviseable
19:32.46 Maloeran I'm just not too inspired to demonstrate raytracing on a crummy Sempron with 256kb of L2 cache when I have a desktop 15 times faster

19:34.51 IriX64 Maloeran, buy a seat for it.
19:35.50 IriX64 like viola players do
19:36.18 Maloeran Ouch, is that the only safe way? I'm not sure they would really let someone carry a big computer case in the plane, they tend to be paranoid enough
19:36.37 IriX64 say its a viola :)
19:39.11 *** join/#brlcad dli (n=dli@wireless-230-163.uchicago.edu)
19:40.25 IriX64 mmm maybe a pet cage then?
19:41.20 dli I made some drawings, but forgot the set units to "in". It's "mm" now, how could I fix this?
20:02.16 IriX64 mc
20:02.20 IriX64 sorry
20:14.25 CIA-21 BRL-CAD: 03brlcad * 10brlcad/TODO: Use NSIS instead of InstallShield/MSI for Windows binary releases and Generate plain .zip files too (suggestion by f_noel and others via irc and myself, msi is crap)
21:00.40 IriX64 is there such a thing as a weekly snapshot of brlcad source?
21:18.13 *** join/#brlcad docelic (n=docelic@212.15.172.73)
22:42.10 louipc dli: maybe you can change the setting to inches and scale everything down
22:42.36 dli louipc, not sure about scaling :(
22:42.43 louipc IriX64: you should really check out CVS man
22:43.03 dli louipc, I'm going to edit the binary .g file
22:43.15 louipc what's wrong with scaling?
22:43.37 dli louipc, I see it's easier to go with binary editor
22:43.51 dli louipc, just one step, 1.00 => 2.54
22:44.34 dli louipc, I haven't finished "scaling" in tutorial yet
22:44.41 louipc hehe ok
22:45.45 dli louipc, scaling/matrix messed up
22:46.05 louipc where in the file do you edit the units?
22:46.09 dli louipc, I think the qcad idea is better, numbers can be in any units, so, make the numbers abstract
22:46.15 louipc oh I see
22:46.58 louipc units^@1.
22:47.01 louipc 0000000000000000000000000e+00
22:47.08 louipc that's some crazy accuracy
22:47.14 louipc er precision
22:48.01 louipc dli: yeah the numbers are just interpreted based on what you label the drawing
22:49.07 louipc but imagine importing a drawing that you drew based on metric into a drawing you drew based on imperial
22:49.44 louipc the metric parts would be much bigger... so I guess it's kind of nice to base the units off of a standard
22:50.13 dli louipc, no, doesn't work :(
22:51.18 *** join/#brlcad dli (n=dli@wireless-230-163.uchicago.edu)
22:51.30 dli louipc, no, binary editor doesn't work. now, help to scale
22:52.00 louipc dli: to convert from metric to imperial you should divide by 25.4 actually
22:52.19 louipc base units in metric is MM, not CM
22:53.45 louipc hehe I'd have to go through the tutorial again myself
22:53.59 dli louipc, you do a test, you will see it fails :(
22:55.27 dli tell them to make the number and units independent :(
22:55.31 louipc yeah I usually don't muck around in binary files :/
22:55.47 dli louipc, I don't know how to scale
22:57.20 louipc hmm lets see
23:02.14 dli louipc, this is very nasty :(
23:05.19 louipc hmm ok you can change your settings to inch and load in the file
23:05.30 louipc then you need to scale it down
23:05.47 dli louipc, how to scale?
23:09.19 louipc hehe good question
23:10.31 dli louipc, all I can see it to scale all prim and matrix :( to redraw everything is even easier
23:11.04 dli louipc, I can scale the final combination, but the leaves all prims with funny numbers, not a solution at all
23:12.35 louipc how did you scale it?
23:13.59 dli louipc, go to Edit -> Prim Selection or Matrix selection
23:14.43 dli louipc, then, you can " sca <factor>", or "oscale <factor>"
23:17.19 louipc ok
23:18.53 louipc I'm not sure. I haven't actually used brlcad for a long while. It should be easier though shouldn't it?
23:21.04 louipc I'm really just trying to get brlcad and all the dependencies packaged nicely for my distro for now
23:21.38 dli louipc, I use gentoo, so, easier with a simple ebuild file
23:22.55 louipc dli: yeah I made a basic package that just uses the stuff in src/other but I want to split those into separate packages so I don't need to re-install them every time
23:23.20 louipc plus someone might find them useful for other purposes
23:25.24 dli louipc, I'm going home :( feel stupid now, probably, redraw everything is easier
23:25.45 dli louipc, btw, exporting as ascii doesn't work
23:25.51 louipc yeah but you won't learn how to scale then
23:26.00 dli louipc, otherwise, we can edit the ascii file
23:26.12 louipc yea
23:26.24 dli louipc, I mean it exports, but that ascii file is invalid at importing
23:27.03 louipc oh hmm. I'm not sure how it's formatted so I couldn't say what's wrong
23:27.29 dli louipc, brlcad complains it's wrong
23:27.43 brlcad IriX64: there were snapshots, but they're not on-line atm
23:27.54 louipc I understand
23:28.22 louipc dli: I meant I couldn't specifically say what the problem is
23:29.02 brlcad louipc: units issues?
23:29.21 dli brlcad, yes, how to change units from "mm" to "in"?
23:29.33 brlcad type: units in
23:29.41 dli brlcad, "inch"
23:29.55 dli brlcad, no :( it scales the coordinates
23:30.40 brlcad then sounds like you don't want to just change the units being used, but resize things that are already created?
23:31.10 dli brlcad, no. I forgot to set it to "in", now, how to correct this mistake
23:31.40 louipc created a model basing it on 'in' but actually drawing in 'mm'
23:32.26 dli louipc, yes, because I'm going to import this part into another database, I couldn't just ignore this
23:32.26 brlcad gotya, so basically everything is too small
23:32.49 louipc yea
23:32.54 dli brlcad, yes, also, funny numbers
23:33.23 dli brlcad, I can use oscale to scale the whole combination, but still leaving prim at funny numbers
23:33.50 louipc hmm
23:33.54 brlcad indeed, hmm
23:34.12 brlcad what do you mean by funny?
23:34.46 dli brlcad, because it has been scaled from correct values
23:35.13 louipc so the scale can apply to the combination as a whole and not affect the prims?
23:35.15 brlcad er, huh? :)
23:35.52 brlcad i'm not following .. funny as in "seems wrong" or just undesirable, or something else?
23:35.54 dli brlcad, the geometries are with correct numbers + wrong units. how to correct this
23:36.43 brlcad assuming you don't have other matrices, the easiest is to just apply a matrix edit and push it
23:37.00 brlcad oed, sca, accept done
23:37.24 dli brlcad, okay, I will forget this, just redraw everything. I already knew your solution :( which is not a solution to me at all
23:37.46 brlcad curious, why?
23:38.03 brlcad there are other ways too, but that's one of the faster direct ways
23:38.52 dli brlcad, I have an one inch cube, so I want to see ( -0,5 0.5 ), not ( -0.019, 0.0019)*25.4
23:39.57 dli brlcad, even worse, during editing, I see ( -0.019, 0.019) with cat, and go to matrix selection to see the 25.4
23:40.48 dli brlcad, is there anyway to make ascii database work? I can modify there
23:41.34 brlcad dli: do you have other matrices in your combinations?
23:41.43 brlcad if not, it sounds like the missing step is push
23:41.54 brlcad push will apply the matrix to the primitves
23:41.59 dli brlcad, yes, and this part will be imported to another database
23:42.35 dli brlcad, hold on, I don't know the "push" command
23:42.52 brlcad push gets rid of the matrices, applying them
23:43.45 brlcad so instead of being a sphere centered at 0 0 0 with radius 10, with a pushed matrix, that might reposition, rescale, etc depending on the matrices above it
23:44.07 brlcad if you need to retain the matrices, though, then you don't want to push
23:44.34 dli brlcad, no, that doesn't help with prims
23:44.58 brlcad another alternative, going the ascii route is to do a "keep" or File->Export in mged or g2asc on command-line, then edit direct
23:45.36 brlcad everything is numerically stored in mm, so you'd edit units to say "in" and update the values accordingly
23:45.42 dli brlcad, I tried the ascii database, but can not import the file
23:46.33 brlcad why not?
23:47.04 brlcad it will be sensitive to typos and other errors
23:48.34 dli brlcad, I can import now. let me try to edit it
23:48.48 brlcad i can ask one of the expert modellers what they do tomorrow, there could be a command that does exactly this that I just don't know about
23:50.13 dli brlcad, so I have to change numbers in the ascii file too?
23:50.54 dli brlcad, I feel it's easier to redraw everything manually
23:59.29 IriX64 what other pastebins are there besides pastebin.ca and pastebin.org?
