| 12:30.28 | drv_ | Hi :) If I will start to work on raytracing I should use OpenCL branch instead main trunk? I have some problems with it... For example CL kernel have syntax errors (?). Was this branch tested? |

| 13:29.02 | drv_ | Ok. And do you know how to copy mged output? In help is written that "ButtonPress-2" will begin "text operation". It's about copying? I've tried it with C, Ctrl-C, Ctrl+Shift+C... I misunderstand something? |
| 13:48.00 | teepee | drv_: sorry, no idea |
| 13:51.31 | drv_ | So maybe you know how to raytrace a file from command line? |
| 13:52.17 | teepee | not really, I'm hanging around here mostly because of GSoC |

| 19:44.45 | javampire | hi all, anybody knows by heart where I find the BRL-CAD primitive parameters explained on an image ? I'm playing with ASCII-art versions of that, which possibly can be included directly in the source code, like this one: |
| 19:44.51 | javampire | http://codepad.org/QDcJR7J3 |
| 19:52.28 | teepee | javampire: that http://brlcad.org/~gcibhlegm/piwigo/_data/i/galleries/diagrams/primitives-me.png ? |
| 19:53.57 | javampire | teepee: nope, I think there were somewhere images for example with the order of the points of an ARB8 |
| 19:54.10 | javampire | or the meaning of the parameters of a torus |
| 19:54.12 | javampire | and similar |
| 19:56.09 | teepee | ahh, that I don't know |
| 20:20.50 | Notify | 03BRL-CAD:starseeker * 60430 brlcad/trunk/src/tclscripts/tkcon.tcl: trim tkcon down a bit more... |
| 20:44.49 | *** join/#brlcad kesha (~kesha@14.139.122.114) | |
| 21:39.47 | javampire | this the kind of thing I had in mind: |
| 21:39.48 | javampire | http://codepad.org/1lNAzM17 |
| 21:40.23 | javampire | the advantage against images is that it can be pasted directly in the source code too |
| 21:40.46 | javampire | so whoever does anything on the primitive's code, can see what it looks like |
| 21:42.25 | javampire | if it's marked appropriately, the same can be included in any other kind of documentation, ASCII-art is something which can be displayed anywhere a fixed size font is available... |
| 21:48.17 | Notify | 03BRL-CAD:starseeker * 60431 (brlcad/trunk/include/bu/cv.h brlcad/trunk/src/libbu/CMakeLists.txt brlcad/trunk/src/libbu/tests/CMakeLists.txt): Add base64 encoding and decoding to libbu, based on the public domain libb64 implementation at sourceforge. |
| 21:49.05 | starseeker | javampire: nice! |
| 21:49.47 | starseeker | are you doing that by hand? |
| 21:50.03 | javampire | starseeker: I use jave for the basic shape then fix by hand |
| 21:50.29 | ``Erik | I always used the ascii when needing that info... there might be some buried in various reports, but I don't think there's a canonical graphical repo of that :/ |
| 21:50.50 | javampire | well why not including in the code ? |
| 21:50.54 | javampire | in some way |
| 21:51.13 | javampire | so that it can be automatically included in the man page too perhaps |
| 21:51.46 | starseeker | javampire: my first guess as to where to put those would be include/rtgeom.h |
| 21:52.24 | javampire | ok, will have a look |
| 21:54.15 | javampire | hmm, rtgeom.h is indeed a good place, but I would like to do it in a way which allows a man page of all primitives explained |
| 21:54.38 | javampire | and that generated by a script if possible |
| 21:54.46 | starseeker | javampire: you'll want to wrap them so they show up in the doxygen output - see, for example, src/libbrep/libbrep_brep_tools.h |
| 21:55.31 | javampire | yep, that looks good ! |
| 21:56.21 | starseeker | javampire: um. We've looked a little bit a generating such pages from the source code - see the attributes man page in doc/docbook/system/man5/en - but for now we aren't ready with the infrastructure that would let us generate such a page properly |
| 21:57.02 | starseeker | I'd put them in rtgeom.h for now (which *is* where the canonical internal structures live) and we'll figure out how to generate DocBook from it later |
| 21:57.28 | starseeker | in the meantime, the doxygen page for rtgeom.h will be a decent start on a "primitives explanation" page |
| 21:59.54 | javampire | yes, it sounds like a good plan |
| 22:00.50 | javampire | but I would still like to find again the work already done in this area, at least to be consistent with it... |

| 22:01.07 | javampire | anybody remember where those pictures live ? I'm sure I have seen something already |
| 22:01.39 | javampire | but can't find it now on google or brlcad site |
| 22:05.13 | javampire | starseeker: OK, there is one small problem with the rtgeom -> for example the arb4-7 are all mapped to arb8, but they need the most an explanation of how that mapping is done... |
| 22:06.21 | javampire | so basically that would mean that all that info is put to ARB8 in rtgeom.h, I don't think there's any other good solution |
| 22:06.49 | javampire | but the actual code of mapping is in wdb.c |

| 22:41.57 | brlcad | javampire: there's an appendix at the end of the mged tutorial (on the website, under documentation) .. it has most of the common ones |
| 22:42.22 | brlcad | there are also several gci tasks that visually documented the parameters for most primitives, but they're not organized or easily accessible right now |
| 22:42.36 | javampire | brlcad: thanks, will have a look |
| 22:43.03 | javampire | would it be possible to publish those gci results somewhere ? |
| 22:43.21 | brlcad | the source files actually often have a diagram or description too, in src/librt/primitives/[obj]/[obj].c |
| 22:43.38 | javampire | ok, will look there too |
| 22:43.51 | brlcad | yeah, the intent IS to make them part of our docs as a "primitive overview" document |
| 22:44.10 | brlcad | but they're not easily accessible right now |
| 22:44.49 | brlcad | (the gci site won't let us get to our list of completed tasks, so have to do a google site: search) |
