| 16:04.41 | mycr0ft | hiya |
| 16:05.08 | mycr0ft | was compiling brlcad, had a problem, then figured out it was an nvidia problem. |
| 16:05.27 | mycr0ft | All before asking anything in here. Mind if I lurk for a while? |
| 16:07.57 | brlcad | lurk as long as you like :) |
| 16:40.00 | mycr0ft | anybody contribute a gentoo ebuild for brlcad? |
| 17:20.22 | brlcad | someone was working on it, but they haven't been around in a while |
| 17:21.34 | brlcad | if you do make one, I'd like to try to integrate it into cvs so that the ebuild is automatically updated when we make a release |
| 17:40.04 | brlcad | the biggest problem that we have to address is the fact that with our dozen libraries and hundreds of applications, there's a good chance we'll conflict with something already installed |
| 17:40.49 | brlcad | our traditional solution and preference is an isolated install root (e.g. /usr/brlcad) like X11 does |
| 17:41.52 | brlcad | the packaging systems discourage that for consistency's sake so some changes might be warranted in the build system to put things in different locations |
| 17:42.14 | brlcad | if you know of any other general policy for resolving conflicting names, I'd be glad to hear about them |
| 17:44.21 | mycr0ft | hehe, nope |
| 17:44.43 | mycr0ft | at least having an ebuild for local installs would be useful |
| 17:45.10 | mycr0ft | even if directory placement offends the sensibilities of the powers that be |
| 17:45.27 | mycr0ft | I had no problem installing into my /home |
| 17:45.41 | brlcad | :) |
| 17:45.47 | mycr0ft | So a /usr/local or a /usr/brlcad should be fine too. |

| 19:07.37 | noyb | it seems that all of the mirrors have the wrong size file. I had the file already, and it matches the md5 but the ones on the mirrors do not. strange. |

| 23:00.07 | brlcad | you had better news last time |
| 23:00.15 | narnia | brlcad, i have 30,000+ pages of legal documents on a cdrom. the opposing lawyers now want me to print them out. |
| 23:01.36 | narnia | i figure that is 5 cases of paper and at least two laser jet toners or 12 ink jet cartridges for the hp all-in-one 7100 of my daughter. |
| 23:02.07 | noyb | take the job to Kinko's... get a receipt and slap it on the other lawyers when you win... :-) |
| 23:02.11 | narnia | the legal documents are e-mail messages in mbox format. |

| 23:02.53 | narnia | kinko's want $3000.00 usd to print it. needless to say i do not have $3000.00 usd. |
| 23:03.36 | brlcad | shouldn't your lawyer be dealing with that? |
| 23:04.04 | noyb | print it in *very* small print... ? (they probably didn't specify) :) |
| 23:04.23 | narnia | brlcad, my lawyers fought hard to prevent the opposing lawyers request. |
| 23:04.44 | noyb | 3 points should be fine, and with mpage you could get 9 or 16 "pages" per page... |
| 23:05.44 | narnia | the opposing lawyers won their argument when they produced reams of paper of e-mail messages in mime format ( base64) not human readbale. |
| 23:06.35 | narnia | it is a stalling tactic. |
| 23:06.37 | brlcad | that would usually imply office documents |
| 23:07.52 | narnia | i also have my job search data on the cdrom. 6000+ possible job hits which i sent resumes to. those are in html. |
| 23:08.41 | narnia | there are also pdf and ps (postscript files). |
| 23:08.46 | CIA-3 | BRL-CAD: 03brlcad * 10brlcad/ChangeLog: add the last minute solaris fixes |
| 23:09.43 | narnia | the opposing lawyers also spent nearly an hour questioning me about my never using anything microsoft. |
| 23:10.35 | narnia | i kept telling them i always owned apple macs or ran linux, one of the bsds. |
| 23:11.13 | archivist | sounds good enough for groklaw |
| 23:11.19 | brlcad | let me guess, the requested evidence that you've tried to get a job, you gave them a disc of your e-mail, they printed it out saying "we can't read it", and then got the judge to put the burden back on you |
| 23:11.32 | narnia | yes |
| 23:14.10 | narnia | their request is a two-edge sword. once those 30000+ pages are submitted as evidence for the opposing lawyers to get their copies they have to pay $0.50 us cents per page to the clerk of the court. so they are looking at $15,000.00 usd per copy. |
| 23:15.57 | brlcad | pennies to them in the big scheme of the lawsuit though, I'm sure |
| 23:16.00 | narnia | total court records page count would be close to 100,000 pages. if any side thinks of appealling to higher courts it will cost roughly $50,000.00 usd for a single copy of all court records. |
| 23:19.35 | narnia | i feel sorry for the clerk who has to stamp all those pages with an evidense stamp. |
| 23:20.57 | brlcad | they're either getting paid minimum wage or they have a machine to do it |
| 23:21.35 | narnia | no they hand stamp each page. |

| 23:37.51 | brlcad | ask away silly asking person |
| 23:38.32 | cad285 | I'm interested in hijacking the brlcad raytrace code to make my own optical design software. |
| 23:38.52 | brlcad | that's what it's designed for |
| 23:38.55 | cad285 | In particular, I would like code that finds where ray's intersect geometry. |
| 23:39.02 | cad285 | err.. rays. |
| 23:39.15 | brlcad | okay |
| 23:39.21 | cad285 | I'm confused about the difference between librt and rt |
| 23:39.30 | brlcad | there are at least a dozen examples of that :) |
| 23:39.48 | brlcad | the difference is mostly design and separation |
| 23:40.00 | cad285 | Ok, well, this is great news. |
| 23:40.13 | brlcad | much of what is in rt should be in librt, but for historic reasons it's in the "front end" |
| 23:40.17 | cad285 | Which one provides the lowest level access to geometrical primitives? |
| 23:40.29 | brlcad | "rt" is the actual BRL-CAD raytracer of 20 years age |
| 23:41.12 | brlcad | brl-cad actually includes several different kinds of raytracers, all based on the same back-end and library code |
| 23:41.53 | brlcad | first off, have you read the application programmer's tutorial? |
| 23:42.03 | cad285 | No. |
| 23:42.14 | cad285 | I should start there I suppose :) |

| 23:43.06 | brlcad | along with other kinds of examples |
| 23:43.11 | cad285 | I'll try this out, thank you for your help. |
| 23:43.25 | brlcad | there's a pdf presentation that was given as well on that link that explains most of the interface |
| 23:44.00 | brlcad | the basic idea is that you write hook functions for a hit, a miss, and maybe an overlap as well as a few other possibilities.. most only care about hit/miss |
| 23:44.41 | cad285 | And brlcad has its own language to feed in a geometrical model? |
| 23:45.26 | brlcad | the ray setup is up to you to describe since some fire single rays, some fire grids, some fire volumes, etc -- but the existing raytracers in src/rt/ will give you working code examples |
| 23:45.39 | brlcad | it's own language? there is a brl-cad .g file format |
| 23:46.00 | brlcad | there's also a brl-cad ascii .asc file format |
| 23:46.29 | brlcad | the routines for writing out those geometry files are also talked about in other places |
| 23:46.33 | cad285 | Ok, I should just start reading. |
| 23:46.49 | cad285 | Thank you for your help. |
| 23:46.54 | brlcad | if all you need to do is "write" geometry.. then libwdb (write database library) is where to start |
