c986721fb6 Added btGhostObject to projectfiles 
btGhostObject can be used for character control, fast short-ray tests, explosions, collision trigger zones etc
See Demos/CharacterDemo/KinematicCharacterController.* for example use. We add some explosion demo before next release.

4cbb3f2e7b Added btGhostObject and btPairCachingGhostObject functionality. 
It is a fast way to keep track of overlapping objects in an area, and doing rayTest and convexSweepTest for overlapping objects, instead of btCollisionWorld::rayTest/convexSweepTest.

Updated KinematicCharacterController to use btPairCachingGhostObject.

b48d05d52a Preliminary adding btGhostObject. 
It can be useful for collision sensors, explosion objects, character controller etc.

Similar to Havok phantom object.

945b299e56 some rayTest improvements in btDbvt::rayTestInternal, it avoids/reduces memory allocations during stack allocation (by sharing a persistent m_stack) 
and rayTestInternal re-uses precomputed invRayDirection/signs.
also did some performance comparison with different ray-AABB test, from 
http://jgt.akpeters.com/papers/EisemannEtAl07/

In short: it is faster, but it is not clear how to cull ray segments using ray slopes: when rays starts inside the AABB, we get a negative t value, but negatives also get false t-values...

60ce828419 Autoformat selection for soft body, btDbvt related classes (no code change, just layout using Visual Studio) 2008-10-15 18:39:27 +00:00
erwin.coumans
cac172d422 Use consistent rayFrom/rayTo API for rayTest for btDbvt and btSoftBody, instead of rayCast/collideRAY(origin,direction). This means RayFromToCaster has a fraction [0..1] instead of distance [0..INF] 
Renamed collideRay -> rayTest to reflect change to (rayFrom,rayTo) interface.
Re-use btRayAabb2 function from src/LinearMath/btAabbUtil2.h in btDbvt instead of duplicated implementation.

e6c850f13b Fix/improve raycast performance for btBvhTriangleMeshShape (btQuantizedBvh, btOptimizedBvh) 
Add raycast acceleration for btAxisSweep3, using btDbvtBroadphase, providing large speedup. Can be disabled in constructor to safe memory.

fffca75e9f Make raycast benchmark default, to show improved raycasting performance. 
Add rayTest to btBroadphaseInterface, and implement efficient version for btDbvtBroadphase to accelerate raycasting.
btAxisSweep3, btSimpleBroadphase and btMultiSapBroadphase implement brute-force method (as before). For now, it is recommended to use btDbvtBroadphase for fastest world raycast.

2998d2a8f3 Added ReadBlend, a data extraction API for Blender's .blend files 
This can come in handy, to author physics data for Bullet from Blender, and directly get the physics data straight from the .blend file

Thanks a lot to Adam D. Moss, to digg up this code and make it available under the MIT license
It was mentioned several years ago in this thread:
