00:58.31 Yoshi477 so i redid my impeller, with all the steps laid out, now to tidy up the tutorial and then rerun all the commands and see if i get the same thing!
00:58.37 Yoshi477 Ralith, im close!
00:58.48 brlcad awesome!
00:59.30 Yoshi477 oh and i figured soemthing out, clone -b 12 0 0 390 blade.r
00:59.41 Yoshi477 you have to add the degrees to 360 and then you get the spacing right!
00:59.48 Yoshi477 unless im doing it wrong
01:05.12 brlcad mm, sounds like you were either doing something wrong or expecting something wrong.. could be the starting position/orientation of blade.r
01:05.27 Ralith Yoshi477: yay!
01:05.50 Yoshi477 Tribute for my son!
01:06.28 Yoshi477 He went to Heaven 1 year ago!
01:08.30 brlcad my condolences, presuming his departure was tragic
01:09.54 brlcad sounds like a noble tribute
01:09.54 Yoshi477 He had HLH a rare blood disease and after a year of treatments and fighting it he passed away, considering he had this, we had lots of fun together and there were a lot of good days, got tons of video and he was one of the most happy kids out side the hospital.
01:10.14 Yoshi477 and then 2 months after he dies his sister got the same thing(genetic)
01:10.19 brlcad long live the best of memories
01:10.42 Yoshi477 and then she did a different course of treatment, she got a bonemarrow transplant in Feb, and is recovering very well!
01:10.53 brlcad wow, outstanding
01:11.01 Yoshi477 she is happy most of the time(she on steriods, kinda makes them grumpy!)
01:12.05 Yoshi477 shes a miracle child, she was in the ICL with 4 failed organs and on the oscillator ventilator and was the 4th kid in the 40 year history of the hospital to come off of it and recover, so we are very thankful for that!
01:12.45 Yoshi477 anyways, if you want to know more you can ask, other wise i will get back to work and try to finish more of my Tribute to Hendrik!
01:13.10 brlcad yeah, talk about beating odds, fantastic to hear she's recovering
01:13.26 Yoshi477 maybe i'll post a video of last summer when he was kinda normal then you will see he had somewhat of a happy life!
01:18.23 Yoshi477 its uploading hopefully it works!
01:33.12 Yoshi477 wel lmy cloned failed, it put an extra one in there! guess i start over and see with 11
01:43.34 Yoshi477 brlcad, can you render my new impeller in glass and chrome?
01:45.27 Yoshi477 oh does this movie work for anyone? http://ej.nijenhuis.pixi.me/v/Movies/00025.mpg.html
01:47.31 Yoshi477 i think i might have to resize it
01:50.27 Yoshi477 brlcad, heres a text file with all the steps needed to recreate the impeller, http://ej.nijenhuis.pixi.me/d/2452-1/impeller.txt?g2_GALLERYSID=8d870d26847034d67e6a9b58f984d434
01:50.50 Yoshi477 if you have a chance please render, im off for now,
01:52.09 brlcad looks
01:52.38 brlcad that's a dead movie link, empty gallery
01:53.33 Yoshi477 yep, i just delete convert the huge mpg into a smaller ogg for easier inbrowser viewing, or anotherformat if you have a suggestion?
01:54.17 brlcad ogg is only easier on linux :)
01:54.55 Yoshi477 what video format is fully support by firefox 3.5 now?
01:55.35 brlcad depends on the codecs you install
01:55.55 brlcad mpg (2 or 4) should work I'd hope
01:56.13 Yoshi477 nope ogg, is the only fully support video format for firefox 3.5 with out any other stuff
01:56.17 Yoshi477 HTML 5 standard
01:57.17 brlcad it was removed from html5
01:57.32 brlcad couple years ago..
01:58.00 brlcad yeah, here we go: http://en.wikipedia.org/wiki/Ogg_controversy
01:58.33 Yoshi477 https://developer.mozilla.org/En/Using_audio_and_video_in_Firefox
01:58.40 brlcad ff 3.5 is actually the only browser to support it :)
01:58.53 Yoshi477 yes!
01:58.58 Yoshi477 im goign to convert and upload
01:59.03 brlcad don't get me wrong, I love ogg
01:59.11 Yoshi477 are you going to try the impeller steps?
01:59.27 brlcad just not yet very practical video format for most still yet
01:59.31 brlcad already tried
01:59.41 brlcad you have some globbing in there so I couldn't just source it
02:02.30 Yoshi477 really, i tried it and it worked
02:02.33 Yoshi477 umm what lines?
02:02.59 CIA-28 BRL-CAD: 03brlcad * r35865 10/brlcad/trunk/TODO: a db_glob expression that doesn't match anything should not return the expression.
02:03.39 brlcad you can type it
02:03.41 brlcad you can't source it
02:03.58 brlcad globbing is not available via source command
02:04.07 Yoshi477 globbing?
02:04.08 brlcad well it is, but not the same way
02:04.10 Yoshi477 im lost
02:04.15 brlcad don't worry about it :)
02:04.25 Yoshi477 oh
02:04.31 brlcad I got it to work with a one-line tweak
02:04.36 Yoshi477 lol
02:04.40 Yoshi477 i figured you would
02:05.12 Yoshi477 how detail should i make the tutorial, for total newbies or someone who know how to use the interface?
02:06.50 brlcad there is a typo somewhere in your script though
02:06.52 brlcad the clone line
02:07.01 brlcad there's a kill embedded
02:08.08 Yoshi477 yep got it, thanks
02:09.19 *** join/#brlcad KingofCSU (n=king@222.247.155.229)
02:10.49 brlcad also it doesn't make an impeller for me :)
02:10.59 brlcad the booleans don't seem right
02:11.00 Yoshi477 huh?
02:11.08 Yoshi477 i tried it 2 times on this side
02:14.11 Yoshi477 the clone should also be 13!
02:14.34 brlcad try this, comment out the kill line, then run:
02:14.40 brlcad mged -c impeller.g "source impeller.mged ; e impeller.c ; rt"
02:14.50 brlcad where impeller.mged is your script
02:15.02 brlcad and impeller.g doesn't exist yet
02:15.35 Yoshi477 if i changed clone to 13
02:15.44 Yoshi477 or not i have a impeller
02:16.53 Yoshi477 can i just leave my text file as is and rename to impeller.mged
02:17.18 brlcad you an just put the name of your test file
02:17.43 brlcad mged -c blah.g "source whatever ; e impeller.c ; rt"
02:18.09 Yoshi477 ouch
02:18.28 Yoshi477 your right, but if i do it line by line it works?
02:18.29 Yoshi477 wierd
02:19.12 Yoshi477 does it follow the script in order and line by line?
02:19.24 brlcad yeah
02:19.54 brlcad g_diff your.g blah.g
02:20.01 brlcad will compare to .g files and report the differences
02:21.35 Yoshi477 why does kill *1300 work in mged and not in the script?
02:22.03 Yoshi477 Segmentation fault
02:22.06 Yoshi477 when g_diff
02:22.56 brlcad via the source command, it has to do with globbing
02:23.23 Yoshi477 ah, ok well i got to get to bed,
02:23.23 brlcad huh, would be interested in seeing the stack trace for the segfault
02:23.32 Yoshi477 command?
02:23.45 brlcad globbing is a detail you probably don't really want to think about just yet :)
02:23.55 Yoshi477 at least not tonight
02:23.58 brlcad right
02:24.16 Yoshi477 so how do i get the stack trace? strace?
02:24.21 brlcad no
02:24.33 brlcad gdb --args g_diff your.g blah.g
02:24.35 brlcad run
02:24.37 brlcad bt
02:24.43 Yoshi477 bt?
02:24.51 brlcad you type those two into gdb
02:24.55 brlcad run
02:24.56 brlcad bt
02:25.12 brlcad it's the short-hand for backtrace

03:10.51 starseeker snorts. Yeah, a default video codec in all browsers is currently impossible.
03:11.21 starseeker The commercial guys want something where they can buy rights to patents/license codecs so they know they're in the clear, and the open source guys won't touch anything like that
03:12.50 starseeker two opinions on that topic - one is that only something untaintable by patents is workable (ogg crowd) and the school that says such a beast is legally impossible under the current system (commercial folk, afraid a patent will appear of of nowhere to make trouble)
03:20.33 starseeker wonders if a container format could be tweaked to query the player for a list of supported codecs and then submit a load request to the server for a supported format...
03:37.01 starseeker brlcad: so what do you want to do about converting clines to brep?
03:37.21 starseeker can go cline->pipe->brep or implement two brep routines
03:44.19 brlcad cline is a lot like old bspline/nurbs
03:44.55 brlcad it should be easy enough to write a cline_to_pipe routine that goes from one internal to the other, so you can call the pipe routines
03:45.18 brlcad wouldn't implement it twice, not worth it
03:46.39 brlcad should be officially gutted for v6 and put on the chopping block, make fast4-g bring in pipes instead and make cline go away when v5 disappears (having it call pipe routines in the meantime)
03:47.41 brlcad an entire day to write one fncking paragraph.. this is so bass ackwards

12:49.17 brlcad yeah, there are a few
12:49.56 brlcad mafm's shots are at http://brlcad.org/~mafm/g3d-screenshots/
12:51.57 brlcad there's at least one at http://brlcad.org/wiki/User:Ralith of the qt-integration
12:54.09 starseeker http://bzflag.bz/~starseeker/g3d_latest.png
12:58.38 Yoshi47 whats G3D?
12:59.08 ``Erik experimental gui replacement for MGED
12:59.29 Yoshi47 but not being worked on anymore, cause of archer?
12:59.41 ``Erik well, it's kinda the follow-on to archer...
12:59.49 Yoshi47 ah?
13:00.18 Yoshi47 should i be using it? can i?
13:00.26 ``Erik it's mostly being worked on in the summers by students (usually under the GSoC banner)
13:01.18 ``Erik nah, you should just be happy that some day, there'll be a more 'modern' and 'user friendly' gui :)
13:01.43 Yoshi47 ok
13:01.50 Yoshi47 i'll wiat patiently
13:02.16 d-lo thanks for the linkage!
13:03.45 Yoshi47 brlcad, get anywhere with those errors?
13:13.52 brlcad Yoshi47: not yet, I had to z too eventually :)
13:14.00 brlcad hopefully some progress later today/tonight
13:14.05 Yoshi47 ah
13:14.12 brlcad you can still manually compare the two

13:14.18 brlcad speak of th edevil
13:14.21 brlcad hi Ralith
13:14.42 Yoshi47 what is he responsible for this!
13:15.04 brlcad Yoshi47: and no, you shouldn't/can't try out the new gui just .. a bit premature for at least a few more months until something can be posted
13:15.22 Yoshi47 sob
13:18.36 brlcad user feedback is always good, but don't really want to get side-tracked with demos until we can do something in response, which won't be for a while
13:18.57 brlcad archer needs to be shored up and an alpha pushed out first, get feedback from that, iterate
13:20.57 Yoshi47 yep i understand
13:24.30 ``Erik huh, wsj thinks nukes might make a comeback
13:27.24 d-lo wsj?
13:28.37 d-lo wall street journal?
13:28.40 ``Erik wall street journal
13:28.43 ``Erik there's a link on /.
13:29.20 Yoshi47 comeback? they were never gone, they just hid them really well
13:29.56 d-lo Well we haven't built a new one in decades. meanwhile France's electrical power is nearly all nuclear :/
13:31.24 d-lo Nuclear power -> Electric cars/trains -> significantly less petrol dependency.
13:31.29 d-lo makes sense to me :)
13:31.40 Yoshi47 yep me too
13:32.31 louipc more solar and wind would be nice though
13:33.24 d-lo Agreed. Much more research needs to be put into thermovoltaic and photovoltaic techs.
13:33.53 ``Erik the issue with nuke+electriccar is how to quickly recharge it I think... X hours to recharge is unacceptable for anything but local commute, and the batteries are wayyyy too heavy to swap out for fresh ones
13:34.12 d-lo righto. Battery tech needs some love.
13:34.42 d-lo But the only real hurdles are battery tech and electrical generation capacity.
13:34.45 ``Erik or figure out a better way to hold the energy, fuel cells tend to have expensive and fragile membranes last I heard
13:35.32 ``Erik honda has a fuel cell electric they're putting to general market, I think? but limited areas, hydrogen pumps aren't the most common :D
13:35.53 ``Erik "fcx clarity"
13:36.14 d-lo Right. Didn't they preview that on Top Gear? I think the initial market is California only.
13:36.19 ``Erik yeah
13:36.36 ``Erik (knew it from top gear, googled around for the name :D )
13:38.02 d-lo tidal energy shows promise, but again, more research needed.
13:41.15 d-lo ohshi, didn't know that Toshiba is in the Nuclear bidness. Huh... i see awesome laptop potental here.
13:41.55 louipc hehehe
13:43.05 ``Erik yeah, but, uh, when the laptop 'battery' explodes...
13:43.44 ``Erik (seems most japanese companies we know about have their fingers in everything, we just hear about their cars or electronics division)
13:44.56 d-lo but imagine the uptime......
13:44.57 d-lo ;)
13:48.25 Yoshi47 didn't philips or panasonic develope a methane battery for notebook, and you could just recharge with a pressurized can!
13:49.08 d-lo heh, cow fart powered.... awesome.
13:49.34 ``Erik has never thought of 'uptime' as the time between explosive launch and stuff hitting the ground before O.o
13:50.33 Yoshi47 lol
13:50.46 Yoshi47 cow burb! more lethal i think
13:51.11 ``Erik "hold up, need to charge my laptop" *plunkt" "mooOOOO????"
13:51.56 Yoshi47 Prof "why does it stink like manure in here!)
13:54.57 d-lo Mr Fusion > Cow Battery imho
13:55.47 d-lo oh and Nuclear reactors don't explode :P
13:56.45 Yoshi47 d-lo, only if you have homer working for you!
13:57.46 ``Erik but, wait, isn't the sun a reactor? and it's exploding as speak (oohssss nnnoooeesssss) :D
13:59.17 d-lo no, its a continous, uncontrolled reaction, not a reactor. Plus, its fusion, and our 'tractors are fission :P
14:07.27 Yoshi47 yep all we have to do is figure out fusion and were good to go
14:10.00 d-lo right. Now... where to start...
14:11.14 starseeker has always thought the concept of "desktop fusion" via very small pockets of very high pressure was interesting
14:12.04 starseeker sorta like how they do super-powered lasers that use as much power as the whole USA for a femptosecond...
14:12.54 starseeker so far as I know no system has convincingly produce such a multiplier system, but the idea is interesting
14:13.17 _clock_ that would be good for free space optics
14:13.27 _clock_ big range :)
14:13.53 ``Erik just happens to vaporize the receiver? :D
14:14.16 _clock_ the receiver has to have suitable dynamic range
14:15.36 d-lo is thinking something along the lines of Star Wars!
14:20.17 Yoshi47 Chain Reaction
14:22.22 ``Erik http://farm3.static.flickr.com/2442/3769270225_7e4aee9082.jpg
14:22.55 brlcad looks like the view from my upstairs
14:23.19 starseeker that's not how I remember Endor
14:23.51 starseeker talk about deforestatino
14:23.57 starseeker deforestation rather
14:24.09 _clock_ deforestatio
14:24.13 _clock_ sounds like some sexual practice
14:24.18 starseeker can't type today, fingers sore after hammering on laminate flooring
14:24.20 ``Erik http://www.vimeo.com/2587071 heh
14:24.47 d-lo starseeker: did you get the snap-fit stuff?
14:25.00 starseeker d-lo: yeah
14:25.07 starseeker even that's taken some time we dont' have to spare
14:26.04 d-lo Suckage. Are you done?
14:26.45 starseeker close
14:26.53 starseeker have to cut some holes for floor vents
14:26.59 _clock_ with megalaser
14:27.04 starseeker then do the closet
14:27.17 starseeker so lot of square footage down, but the hard parts remain
14:28.10 starseeker what we do have in looks really nice, expecially after the sucky blue carpet
14:31.35 ``Erik (shoulda had a housewarming party before ya started, so we could get the before/after impression :)
14:32.01 Yoshi47 took video before any renos
14:32.32 d-lo ``Erik: nice video link. :)
14:33.07 d-lo Yeah, I love how new wood flooring looks :)
