| 14:20.23 | CIA-68 | BRL-CAD: 03starseeker * r52520 10/brlcad/trunk/src/libnurbs/opennurbs_fit.cpp: Remove some debugging output. |
| 14:21.52 | abhi2011 | hey starseeker, is there anyway to disable the multiconfig_path thing |
| 14:22.10 | abhi2011 | it seems to be throwing up some errors in the windows compile |
| 14:27.08 | elf11__ | It is "normal" for the VS brlcad build to have a few GB on the HDD? |
| 14:33.03 | abhi2011 | so about the raytracing algorithm |
| 14:33.22 | elf11__ | yeah? |
| 14:33.26 | abhi2011 | right now we are using the bullet default cube-cube collision algo |
| 14:33.45 | abhi2011 | in fact bullet has specific algos for specific shape pairs |
| 14:33.54 | abhi2011 | (details in the manual) |
| 14:34.46 | abhi2011 | so we need to uncomment the lines 525 to 552 |
| 14:34.52 | abhi2011 | in simphysics |
| 14:35.10 | abhi2011 | thats for registering a custom algorithm for box-box collisions |
| 14:35.34 | abhi2011 | the algo in its current state will probably need fixing |
| 14:36.01 | abhi2011 | so we can pick up a simple case to use for fixing it first |
| 14:36.02 | elf11__ | hmm okay |
| 14:36.17 | abhi2011 | a box on te ground plane |
| 14:36.36 | abhi2011 | the box should stay in its position |
| 14:36.42 | abhi2011 | for al iterations |
| 14:37.50 | elf11__ | right |
| 14:38.00 | elf11__ | a static object so to speak |
| 14:38.13 | abhi2011 | only the ground plane is static |
| 14:38.21 | abhi2011 | the box is dynamic |
| 14:38.27 | CIA-68 | BRL-CAD: 03Abhi2011 * r52521 10/brlcad/trunk/src/libged/simulate/ (simphysics.cpp simulate.c): Removed all the logging lines. |
| 14:38.45 | abhi2011 | in bullet a dynamic object at rest is still dynamic |
| 14:38.56 | abhi2011 | with all velocities 0 |
| 14:40.09 | abhi2011 | there are 2 phases in bullet's collision detection pipeline |
| 14:40.16 | abhi2011 | broadphase and narrowphase |
| 14:40.40 | abhi2011 | in broadphase AABBs are used to generate pairs of objects which are colliding |
| 14:41.11 | abhi2011 | then the narrowphase is used to generate the exact contact points, penetration distance, normals |
| 14:41.26 | abhi2011 | bullet will calculate the reaction force from this data |
| 14:42.05 | elf11__ | okay |
