| 04:20.00 | Stragus | Question, does BRL-CAD use any kind of portable C99-compliant snprintf() and friends? |
| 04:20.46 | Stragus | The one on Windows doesn't understand %lld, it may not terminate with \0 a snprintf() that exceeds the buffer, and a bunch of other "features" |
| 04:20.55 | Stragus | It's causing me a small portability headache |
| 04:46.31 | brlcad | clock: for data visualization? that's one of the primary uses |
| 04:46.46 | brlcad | but not usually graph data |
| 04:49.15 | brlcad | kanzure: I have a pretty diagram somewhere that explains it all, but basically there's two aspects to describing any "Boundary Represenation" (BREP) geometry, namely the geometric entities that comprise an object and the topology (how it all fits together) |
| 04:50.29 | brlcad | kanzuer: they are very much related, but very different conceptually, so pretty much every production system maintains them separately so you can reuse geometry, perform efficient topological queries, and .. much more |
| 04:50.32 | kanzure | i've been wondering about computing the bounding box of an opennurbs surface |
| 04:50.56 | brlcad | so a face is associated with a surface, but also with some number of edge curves and is probably connected to other faces |
| 04:51.47 | brlcad | we have a routine that calculates one somewhere in our extension |
| 04:52.25 | brlcad | to evaluate a bounding box, you have to evaluate the surfaces, which is really tricky (at least to do quickly/efficiently, without blowing out memory) |
| 04:52.28 | kanzure | src/other/openNURBS/opennurbs_surface.cpp GetBoundingBox and GetBBox just sends me on an endless chase |
| 04:52.40 | kanzure | i don't see where it's calling any surface evaluation stuff? |
| 04:53.23 | brlcad | that chase ends up with a non-existent implementation (they intentionally rip that logic out of opennurbs, it's part of their commercial offering) |
| 04:53.30 | brlcad | that's why we had to implement it |
| 04:53.46 | kanzure | hah their bounding box evaluation stuff is ripped out too?? damn |
| 04:53.51 | kanzure | i should have guessed. |
| 04:54.21 | brlcad | some of it |
| 04:54.35 | brlcad | I believe some of the individual pieces, like curves and points and such are all still there |
| 04:54.42 | brlcad | surfaces is where it's hard |
| 04:54.57 | brlcad | but like I said, we implement that now (in libbrep) |
| 04:55.34 | kanzure | thanks, i'll go looking in a bit |
| 04:57.49 | brlcad | we don't back it into a neat routine |
| 04:57.51 | kanzure | it's unfortunate that it was not obvious to me that this piece was missing |
| 04:57.53 | brlcad | but it's there |
| 04:58.03 | kanzure | i thought maybe i was just bad at reading source code |
| 05:00.01 | brlcad | that aspect remains to be seen? ;) |
| 05:00.11 | kanzure | fair enough |
