| 12:48.25 | Azlan | hi.. I'm trying to compile brl-cad on my WinXp computer.. But the problem is.. i looked at the source and there only U*ix scripts.. Any alternative package?? |
| 12:49.29 | Azlan | Should i dl automake for windows to? |
| 12:50.23 | *** join/#brlcad Azlan (~d9d1678f@bz.bzflag.bz) |
| 14:01.57 | brlcad | Azlan: there are studio workspace build files (awefully out of date) in some of the directories that might be helpful |
| 14:02.16 | brlcad | Azlan: more likely, though, the easiest path to getting everything to work is via mingw/cygwin |
| 14:02.49 | brlcad | there are new .net build files being put together, but those will not be likely ready for a while |
| 14:03.40 | brlcad | I'll be glad to help you through any problems you have with the build regardless of the build method, but especially if you choose the mingw route |

| 18:04.47 | brlcad | howdy ho |
| 18:23.21 | narnia | brlcad, you still here? |
| 18:23.53 | narnia | brlcad, sorry i was reading an e-mail list. |
| 18:24.06 | narnia | brlcad, i have some good news. |
| 19:27.55 | brlcad | good news? :) |
| 19:34.34 | narnia | brlcad, you still here? |
| 19:34.56 | narnia | brlcad, yes, good news. ;-) |
| 19:35.50 | brlcad | i'm still here |
| 19:35.52 | brlcad | what's up? |
| 19:36.00 | narnia | brlcad, there you be. ;-) |
| 19:36.07 | brlcad | there I be |
| 19:36.16 | brlcad | and there you be |
| 19:36.31 | narnia | brlcad, i have a pdf copy of 10303-11:2004. express language reference manual edition 2. |
| 19:36.36 | brlcad | heh |
| 19:36.49 | brlcad | I won't ask, but good to hear :) |
| 19:36.59 | narnia | brlcad, it is entirely legal. |
| 19:37.05 | brlcad | ah, even better |
| 19:38.18 | narnia | brlcad, to bring you update to date it may be quicker and easier if you have the time to read the following e-mail list. http://step.nasa.gov/pipermail/step-os/2005-March/date.html |
| 19:38.52 | narnia | brlcad, there are only 16 msgs. |
| 19:38.57 | brlcad | mkay |
| 19:39.27 | narnia | brlcad, the important msg is http://step.nasa.gov/pipermail/step-os/2005-March/000139.html |
| 19:40.00 | narnia | brlcad, perhaps you may obtain a legal copy also. ;-) |
| 19:40.57 | narnia | brlcad, i am comparing the -11:ed2 to nist express lib. |
| 19:42.05 | narnia | brlcad, i figure 5 days to get nist express lib updated. a couple days of testing. then perhaps have the folks on step-os test it. |
| 19:42.22 | narnia | brlcad, the part 21 parser is going okay. |
| 19:44.47 | narnia | brlcad, know anyone knowledgable in step-nc? step-nc is yet another iso standard. in other words obscenely expensive. ;-) |
| 19:46.22 | narnia | brlcad, i am also working on, for my own use, a couple perl scripts to help with the work. |
| 19:49.16 | brlcad | that's pretty cool, hehe |
| 19:49.20 | narnia | brlcad, i am toying with the idea to write a perl script that would take an express file and create an xfig document from it. |
| 19:49.34 | narnia | brlcad, which part is pretty cool? |
| 19:50.18 | narnia | brlcad, i take it you have read the step-os e-mail list. |
| 19:51.11 | narnia | brlcad, any thoughts on the suggestion to implement ap210 since it covers most other aps? |
| 19:54.02 | brlcad | give me a second |
| 19:54.04 | narnia | brlcad, sorry, just re-read that msg. ap203 covers most of the other aps. the person would like the brl-cad to support the gemometry portions of ap210. |
| 19:54.17 | narnia | brlcad, times up. ^_^ |
| 19:55.05 | narnia | brlcad, ;-) i am joking. pulling your chain. pulling your leg. having some fun. etc. |
| 20:27.11 | brlcad | that's about a second, right? :) |
| 20:40.52 | narnia | brlcad, sorry was watching fosset land in kansas. he made it sole around the world non-stop. |
| 20:41.19 | brlcad | not a problem, just reading more of that list |
| 20:41.52 | brlcad | wonder if ap203/214 would similarly qualify as "iso 10303 support activity" :) |
| 20:42.23 | narnia | brlcad, good question. |
| 20:42.56 | brlcad | so the take seems to be that libexpress as received from nist is 1994 compliant but not 2004 |
| 20:43.30 | narnia | brlcad, yes. |
| 20:44.10 | narnia | brlcad, i figure 5 days to get -11:2004 compliant. |
| 20:47.10 | narnia | brlcad, altering the yacc and lex files to keep express ed1 and add epxress ed2 so both will work is time consuming. |
| 20:47.33 | narnia | brlcad, did you happen to read my intro msg? |
| 20:49.09 | brlcad | yes, I read the whole thread |
| 20:49.50 | brlcad | Craig's name is rather familiar too |
| 20:50.11 | brlcad | probably just from exp-engine though |
| 20:50.44 | narnia | brlcad, any comments on my intro? i think i covered what our goals are. |
| 20:51.10 | brlcad | No, looked good |
| 20:51.13 | brlcad | well put |
| 20:51.52 | narnia | brlcad, basically, the 'kiss' philosophy. ;-) |
| 20:52.19 | narnia | brlcad, as in 'straight c, yacc, and lex' |
| 20:53.08 | narnia | brlcad, at some point we will need to create a 'map' from express/step to brl-cad database. |
| 20:53.39 | brlcad | I'm a bit surprised Steve posted, but no matter.. we're now one step closer |
| 20:53.46 | narnia | brlcad, need to search for some gnu gpl or public domain brep to csg routines. |
| 20:54.12 | narnia | brlcad, no pun intended i am sure. ;-) |
| 20:54.24 | narnia | brlcad, do you know steve? |
| 20:54.32 | brlcad | actually that's one of the primitives that just needs to be added as a full-fledged primitive |
| 20:54.57 | narnia | brlcad, ah. |
| 20:54.58 | brlcad | depending on which implementation of brep you're referring to of course |
| 20:55.16 | brlcad | we already do polygonalized brep |
| 20:55.21 | brlcad | we don't do spline |
| 20:55.57 | brlcad | and that's mainly just because the modeler needs a slew of changes to support them |
| 20:56.08 | brlcad | (like a new modeler) ;) |
| 20:56.39 | narnia | brlcad, you should have that done in a day ro two then. ;-) |
| 20:57.41 | brlcad | heh |
| 20:58.08 | brlcad | knowing exactly what I need to do doesn't make it any easier :) |
| 20:58.33 | narnia | brlcad, on a serious note, at some point in the distant future spline brep will be supported. |
| 21:00.28 | jano | buckyballs! |
| 21:01.00 | brlcad | narnia: most definitely |
| 21:05.57 | brlcad | narnia: adding new primitives is only generally difficult in one aspect -- the ray-intersection test |
| 21:06.31 | brlcad | i've been meaning to write a paper on just how to do that, having written two new primitives myself |
| 21:08.15 | brlcad | i'd have to pull up some research papers on implicitly defined spline computations, but I suspect what will be most problematic is the root solver |
| 21:08.48 | narnia | brlcad, umm. |
| 21:08.52 | brlcad | brl-cad's current root solver is one that favors speed over most other qualities because the primitives that use it are _very_ well behaved |
| 21:09.02 | narnia | jana, stickybuns. |
| 21:09.14 | brlcad | a generic spline primitive would not necessarily be so well behaved |
| 21:09.16 | narnia | jano, as in pastry. |
| 21:09.44 | narnia | brlcad, agreed. |
| 21:10.23 | brlcad | There are lots of readily available quadratic root solvers in abundance though .. just need to test them out |
| 21:10.25 | narnia | my typing sucks today. |
| 21:11.15 | narnia | brlcad, will you be around this evening? |
| 21:11.22 | brlcad | should be |
| 21:12.10 | narnia | narnia, okay. i really need to go soak my left arm. i will be back this evening. |
| 21:13.00 | narnia | brlcad, today has been a good day. |
| 21:13.34 | brlcad | indeed! |
| 21:13.43 | brlcad | nice job on the list |
| 21:13.50 | brlcad | I wasn't even aware of that list until now |
| 21:17.27 | jano | soak your left arm |
| 21:17.34 | narnia | brlcad, thank you. i found it yesterday. figured it was worth a shot. |
| 21:17.44 | jano | that's just the most random goodbye statement I've seen |
| 21:18.10 | jano | :D |
| 21:18.17 | narnia | jano, i would but tom, the new puppy, needs someone to watch him. |
| 21:19.02 | narnia | jano, i am the official puppy watcher. |
| 23:52.58 | Azlan | Then mavy its easyer compileing on linux for windows?? Possible? |
