erwin.coumans 0384562db0 removed bloated reference docs, will add them in a separate package 2008-11-10 22:26:16 +00:00
erwin.coumans 85341fee2a fix more places in btSoftBody that assume btRigidBody (it wasn't designed to support btCollisionObject/btGhostObject). 
Add another 'findActiveObject'
 2008-11-10 21:33:11 +00:00
erwin.coumans 3c0ca0d931 Fix btSoftBody issue, so it can interact with btCollisionObject and btGhostObject (and not just btRigidBody and btSoftBody) 
Thank for the report mi076 http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=2823

remove legacy.c from libxml
removed #include <math.h> from btQuadWord.h , it should be centralized in btScalar.h (to allow easier replacement with fastmath.h etc)

erwin.coumans 463a1b74c1 The SPURS version requires 16-byte alignment at the moment, and Cell SDK doesn't, so keep it like this for 2.73. @todo: Need to figure out better way to deal with those differences. 2008-11-09 23:35:23 +00:00

erwin.coumans 82448a3942 minor IFF.h changes to migrate from .c to .cpp 2008-10-27 00:05:32 +00:00
erwin.coumans 14ba3eaff7 rename from .c to .cpp, and updated 23 year old IFF source code (1985) 2008-10-26 23:47:35 +00:00
erwin.coumans 2a721c7489 Updated original EA-IFF-85 files to read and write Interchange File Format files. 
Plan is to convert COLLADA XML into IFF, for faster, more compact and easier to read and parse files.
Reading/writing code is a few hundred lines of code, instead of COLLADA-DOM and libxml combo.
So it would be suitable as a run-time format for platforms ranging from iPhone to PlayStation 3.
Relevant physics data (and perhaps other data) will be converted from COLLADA -> IFF. 
We could call the resulting files COLLADA binary IFF -> CLIFF.
 2008-10-26 23:04:43 +00:00
erwin.coumans 92c69ddefa added missing files to build systems for CMake and Automake (Makefile.am still needs to add additional include directory for BulletMultiThreaded, for vectormath) 2008-10-21 19:06:29 +00:00
erwin.coumans a05ae6e715 added src/BulletMultiThreaded/vectormath/scalar/cpp to include path for BulletMultiThreaded module 2008-10-21 19:05:50 +00:00
erwin.coumans 0d911a6c06 added missing vectormath <-> Bullet conversion file 2008-10-21 18:32:21 +00:00
erwin.coumans c508711108 remove GIMPACT and added new dNailConstraint files to Dynamica Maya plugin projectfile 2008-10-21 04:35:30 +00:00
erwin.coumans e6202f58ad 1)Added SCE Physics Effects boxBoxDistance 
BulletMultiThreaded/NarrowPhaseCollision makes use of this boxBoxDistance.
Cache some values in src/BulletMultiThreaded/SpuContactManifoldCollisionAlgorithm.cpp, to avoid DMA transfers

2) Added btConvexSeparatingDistanceUtil: this allows caching of separating distance/vector as early-out to avoid convex-convex collision detection.
btConvexSeparatingDistanceUtil is used in src/BulletCollision/CollisionDispatch/btConvexConvexAlgorithm.cpp and can be controlled by btDispatcherInfo.m_useConvexConservativeDistanceUtil/m_convexConservativeDistanceThreshold

3) Use BulletMultiThreaded/vectormath/scalar/cpp/vectormath/scalar/cpp/vectormath_aos.h as fallback for non-PlayStation 3 Cell SPU/PPU platforms (used by boxBoxDistance).
Note there are other implementations in Extras/vectormath folder, that are potentially faster for IBM Cell SDK 3.0 SPU (libspe2)
 2008-10-20 20:12:39 +00:00
erwin.coumans 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.
 2008-10-18 05:29:31 +00:00
erwin.coumans 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.
 2008-10-18 01:33:23 +00:00
erwin.coumans b48d05d52a Preliminary adding btGhostObject. 
It can be useful for collision sensors, explosion objects, character controller etc.

Similar to Havok phantom object.

erwin.coumans b32a0e3491 Removed ray-AABB slopes code again, we are not using it and it is archived in Subversion repo now. 2008-10-16 20:19:01 +00:00
erwin.coumans 947a44452d Removed ray-AABB slopes code again, we are not using it and it is archived in Subversion repo now. 2008-10-16 20:18:41 +00:00

erwin.coumans 6fcd824524 Applied filtering flags for CCD Motion Clamping, thanks to Bbilz, see http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=2736 2008-10-16 20:17:56 +00:00
erwin.coumans 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...
 2008-10-16 20:01:02 +00:00
