| 15:16.20 | tandoorichick_ | would it be useful to have a macro in vmath.h for the area of a triangle (say ABC) that can be computed as half the magnitude of the cross product of AB and AC? |

| 16:26.03 | Notify | 03BRL-CAD:d_rossberg * 67094 brlcad/trunk/include/bu/defines.h: regarding rev. 66674: added empty fallback definitions in case of the compiler test variables aren't set |

| 16:54.25 | Notify | 03BRL-CAD:brlcad * 67095 brlcad/trunk/src/librt/bundle.c: make rt_shootrays() fire rays in parallel automatically. this is implemented using the new bu_parallel feature that runs as many threads of execution as can usefully be run, up to the number of available cores, but respecting other bu_parallel threads so the machine is never oversubscribed. it means it'll run as fast as it can cooperatively. currently |
| 16:54.27 | Notify | individual ray dispatching is done one at a time per thread with simple semaphore bookkeeping though we'll eventually want to dispatch bundles coherently for even greater performance. |
| 16:54.29 | Notify | ... |
| 17:06.17 | tandoorichick_ | brlcad: could you tell me where i could find that? i saw that the surface area function for an 'ars' doesn't exit and so decided to work on that. |
| 17:08.31 | tandoorichick_ | would it be right to divide the area between two successive waterlines into triangles and find their area? (i had a confusion because in the case of the 1/8th turn twist shown in the wiki the triangles can be seen only in the raytraced figure.. |
