| 05:56.02 | CIA-8 | BRL-CAD: 03brlcad * 10brlcad/configure.ac: some systems (e.g. solaris) use /usr/X11 instead of /usr/X11R6, so be sure to go there too |
| 06:14.27 | CIA-8 | BRL-CAD: 03brlcad * 10brlcad/configure.ac: add checks for sys/sched.h sys/sysmp.h sys/wait.h ulocks.h headers as well as prtcl() and sysmp() functions |
| 06:14.44 | narnia | brlcad, would you happen to have any preliminary write-ups about the database plug-ins? |
| 06:16.27 | CIA-8 | BRL-CAD: 03brlcad * 10brlcad/src/libbu/parallel.c: ugh, so much to do in this file.. -- use some of the new header and function checks |
| 06:18.18 | narnia | brlcad, also in your copious amounts of free time ( ;-) ) have you had a chance to test the diesel engine step file with pro/e? |
| 06:18.55 | narnia | brlcad, any thoughts on getting the 10k pages scan into pdfs? |

| 15:53.56 | CIA-8 | BRL-CAD: 03lbutler * 10brlcad/include/bu.h: changes to suport Jim Hunt's fast memory debugging |
| 15:56.37 | CIA-8 | BRL-CAD: 03lbutler * 10brlcad/src/libbu/malloc.c: Changes to support Jim Hunt's fast memory debugging |
| 16:17.03 | narnia | brlcad, on a serious note. i think it may be wise to rethink how to implement express/step file in general. i have a good understanding now of how the nist step class library works and while it does work there are, in my opinion, other ways it can be done better. |
| 16:21.08 | brlcad | the other comments weren't on a serious note? :) good to know ;) |
| 16:21.40 | narnia | brlcad, the best analogy i can come up with is perl. the express language is the basis for all other 10303 parts. it appears to me that despite iso stating that the express language is not a programming language there is nothing to prevent us from treating express language as a programming language. |
| 16:22.07 | brlcad | there are writeups on the database plugins, but they are not electronic -- have to scan them in or something |
| 16:22.33 | brlcad | i'm sometimes old-fashioned in that respect when it comes to architecting.. pen and paper, big whiteboards |
| 16:22.48 | narnia | brlcad, just as perl has modules which extend perl the parts of 10303 extend express. |
| 16:23.28 | narnia | brlcad, i have a large easel with a large paper pad mounted on it. color markers. ;-) |
| 16:24.16 | narnia | brlcad, i than tape the paper up to walls, patio doors, nearly any vertical flat surface. |
| 16:25.24 | brlcad | I find index cards extremely helpful/portable along with a small notebook |
| 16:28.38 | narnia | brlcad, paper placemates also work well for notes and drawings. ;-) |
| 16:35.50 | narnia | brlcad, on a side note: a metal working friend who i recommended brl-cad to asked me about auto-dimensioning in brl-cad. i look briefly and did not find any references to auto-dimensioning. it auto-dimensioning currently supported in brl-cad? |
| 16:38.24 | narnia | brlcad, as the awareness of brl-cad increases the requests for 'features' is also growing. is there an official 'wish list'? |
| 16:41.12 | narnia | brlcad, would you happen to have a list of who is working on what? |
| 17:38.02 | brlcad | narnia: auto-dimensioning is not presently supported.. would be nice ;) |
| 17:39.44 | brlcad | narnia: if they are things that you plan on doing, feel free to add them to the TODO in cvs, if they are bigger plans that you intend on doing, there's the sf Task manager. if they are "wish list" items, they belong in the sf RFE section (request for enhancement). |
| 17:41.26 | brlcad | narnia: there isn't a list of who's working on what beyond what people have assigned to them on the bugs and feature request trackers and the task manager .. a couple of the devs don't have sf.net accounts yet either |
| 19:29.46 | CIA-8 | BRL-CAD: 03bob1961 * 10brlcad/src/libbu/malloc.c: *- removed duplicate lines of code (this wouldn't compile on Windows) |
| 19:41.47 | narnia | brlcad, auto-dimensioning, i have to think on this. a couple friends who i have recommended brl-cad to would really like this. two of those friends are also wanting the step support. i really think i have enough on my plate at the moment. |
| 19:47.13 | narnia | brlcad, i recall a past discussion concerning layout nesting. i do not recall what was decided concerning layout nesting. |
| 21:23.01 | brlcad | narnia: in the new modeler, auto-dimensioning and full constraint system will be included -- it'll take more thought to do it in mged.. how would you forsee the interface to auto-dimensioning being? |
| 21:25.12 | brlcad | narnia: as for layout nesting from the linux cad mailing list comment, I researched that for a couple days last week. It'd be really simple to write up a small application or library to do the task in brl-cad for 2d or 3d. the bigger question is what the real need is for as that'll drive what sort of flexibility is needed |
| 21:26.21 | brlcad | example, are we solving the knapsack problem where we have to pick how many N objects fit into a M space or is it merely the best/good fit across an unbounded area? |
| 21:27.13 | narnia | brlcad, i have not given auto-dimensioning any addtional thought. |
| 21:27.37 | brlcad | and what is meant by auto-dimensioning? |
| 21:27.58 | brlcad | in a constraint-based system, it's usually a side-effect of fulfilling other constraints |
| 21:28.01 | narnia | brlcad, the context for nesting is sheet metal and woodworking. |
| 21:28.33 | narnia | brlcad, the request i have received are all 2d. |
| 21:29.39 | narnia | brlcad, given a 4x8 sheet how many of item 'a' can be cut from it. |
| 21:29.48 | brlcad | for a solid modeler that means you have to either have a 2d shape (e.g. sketch primitive in brl-cad) or you have a specific cross-section in mind |
| 21:30.48 | narnia | brlcad, or given items a-f place them on the 4x8 sheet to minimize waste. |
| 21:33.25 | narnia | brlcad, concerning auto-dimensioning the request either refer to autocad or turbo-cad or some other cad program. i have nver used autocad, turbo-cad, or other commercial cad programs. |
| 21:33.57 | narnia | brlcad, i would have to ask them what they mean by 'auto-dimensioning'. |
| 21:36.53 | narnia | brlcad, when i started my gnu-cad-cam project i went around to local job shops and talked with them what they needed. it took alot of talking to understand what they really meant. |
| 21:37.52 | brlcad | I understand, that's why I said there are lots of unanswered questions for what that means ;) |
| 21:38.15 | narnia | brlcad, perhaps this summer it when various 'enhancements' are included and stablized it would be worth having a 'dog and pony' show for the local job shops to get their feedback. |
| 21:38.18 | brlcad | if they want to file up RFE's or interactively work out what they'd like to see, that's fine ;) |
| 21:39.07 | brlcad | I have a todo list out the wazoo already so I'm not exactly in search of something else to do .. |
| 21:39.18 | brlcad | it's a great idea to keep in mind, though, as development continues |
| 21:41.10 | brlcad | it's probably not so apparent in the open source community, but brl-cad does have a long established community |
| 21:41.38 | brlcad | most of those users and codes we have to interact with, though, are not public media knowledge (with good reason) |
| 21:41.57 | narnia | brlcad, understand. |
| 21:42.10 | brlcad | doesn't mean we don't have room to expand into -- we do .. huge room and huge potential |
| 21:42.19 | brlcad | especially in the cadd and cam areas |
| 21:43.43 | narnia | brlcad, i agree with todo list. i have enough at the moment. |
| 21:44.35 | brlcad | basically, if someone wants to add some new feature that has anything to do with cad/cadd/cam, they're quite welcome to join in .. |
| 21:46.03 | brlcad | brl-cad gives them a foundation, user community, modeling methodology, user community, docs, and more for free that can usually be easily extended |
| 21:49.46 | narnia | brlcad, i wish more of the people requesting 'features' were programmers. ;-) |
| 21:51.37 | narnia | brlcad, are you still at work? it is 1651 hours on the east coast. |
| 21:58.39 | narnia | argh |
| 21:58.54 | brlcad | yes, still at work |
| 21:59.12 | brlcad | and YES.. I'm really interested in getting more programmers ;) |
| 21:59.34 | brlcad | but that aspect I won't expect until the prototype for either archer or the new modeler are ready |
| 22:00.41 | narnia | brlcad, that is the second time you have mentioned a 'new modeler'. what 'new modeler'? ;-) |
| 22:01.02 | narnia | brlcad, who or what is 'archer'? |
| 22:02.22 | brlcad | archer is effective an mged replacement prototype written for a project called ajem |
| 22:02.41 | narnia | brlcad, of the 10 members listed on sourceforge who are developers (programmers)? |
| 22:02.47 | brlcad | ajem is a joint collaboration across several military services where brl-cad is one of the backend components |
| 22:03.19 | narnia | brlcad, ajem is not written in java is it? |
| 22:03.21 | brlcad | archer was written for ajem with a more "up to date" gui |
| 22:03.29 | brlcad | no, it's not |
| 22:03.36 | brlcad | ajem is not publicly available either |
| 22:03.38 | narnia | brlcad, thank god. ;-) |
| 22:04.11 | narnia | brlcad, that was a concerning java. |
| 22:04.19 | brlcad | archer is being released back to us in part because it pertains directly to brl-cad |
| 22:04.37 | brlcad | and in part because it was written by one of mged's primary authors |
| 22:04.40 | narnia | brlcad, ah |
| 22:04.50 | brlcad | Bob :) |
| 22:05.03 | brlcad | bob will probably make an appearace in here eventually |
| 22:05.36 | brlcad | you're trapped ;) |
| 22:05.52 | narnia | hehe |
| 22:06.35 | brlcad | every single person listed on the members page is a seasoned programmer with some area of expertise |
| 22:07.20 | narnia | brlcad, is that spicy or mild seasoning? ;-) (sorry i could not resist. ;-) ) |
| 22:08.24 | narnia | brlcad, am i the only 'outsider' ? |
| 22:10.49 | narnia | be back in a bit, news is on. |
