 2007-12-07 19:21:16 +00:00
ejcoumans 6f80b98a67 - fix issue with convex cast: results further away (larger hitfraction) could overwrite closer results 
- minor naming convention thing (variables start with lower case)
- renamed MotorDemo
- added ConcaveConvexcastDemo, Thanks John McCutchan (JMC)
 2007-12-06 02:54:29 +00:00
ejcoumans d53f2875e5 minor fixes, only btBvhTriangleMeshShape should provide getShapeType(), add get methods for motor limits in btHingeConstraint. 2007-12-06 01:41:07 +00:00

ejcoumans 7ef4eab189 use better tolerance, instead of hard-coded 0.0001 inside the btMultiSphereShape supporting vector implementation. 
Thanks to Phil Knight for reporting and fixing this issue (it could lead to failing collisions under certain conditions).
 2007-11-07 13:39:05 +00:00
ejcoumans 282cbdcdd9 applied patch contributed by Tim Johansson: adds support for multiple mesh parts in combination with bvh, add short index support for meshes. 2007-11-06 06:47:04 +00:00
ejcoumans e755d1ed4e added some comments, to clarify unit-test/brute force implementations. 2007-11-02 01:14:29 +00:00
ejcoumans 0723448895 disabled btTriangleMeshShape, to avoid usage, it is very slow performing for larger triangle meshes. Please use the derived btBvhTriangleMeshShape instead. 2007-11-01 23:59:22 +00:00
ejcoumans 2aec2a9969 Added some comments about the btPersistentManifold (contact point cache for potential overlapping pairs)

 2007-11-01 23:42:17 +00:00
ejcoumans dc4aacb03b add ability for user pair callback, this can be used to keep track of objects, overlapping a certain AABB/shape. 2007-11-01 18:21:17 +00:00
ejcoumans f3424f491c cleanup memory in CcdPhysicsDemo, RagdollDemo, ConcaveDemo, BspDemo (work in progress) 2007-11-01 05:50:50 +00:00
ejcoumans a146bbc293 more memory leak fixes in demo and btSimpleBroadphase. 
- deleting object (END key) needs to release
- call destructor of pair cache
 2007-10-31 08:17:48 +00:00
ejcoumans a101719687 - removed warnings in GLUI, thanks Jorrit Tyberghein for the patch!

- added memory leak debugging functionality in btAlignedAlloc.h: #define BT_DEBUG_MEMORY_ALLOCATIONS
 2007-10-31 08:00:03 +00:00
ejcoumans d17a8dae0e updated autogenerated msvc projectfiles, moved destructor in CPP file, it was causing some random crash under msvc 6.0 (todo find out why) 2007-10-25 05:11:19 +00:00
ejcoumans ec76f2e0a3 - keep track of all memory allocations (gNumAllignedAllocs/gNumAllignedFree) 
All memory allocations in Bullet go through btAlignedAlloc/btAlignedFree
Fix in hinge constraint constructors, thanks Marcus Hennix!
 2007-10-22 22:23:10 +00:00
ejcoumans c80d1532f6 made access to mesh interface more consistent, so btConvexTriangleMeshShape uses also 'getMeshInterface', similar to btTriangleMeshShape. 
Thanks Et3D for pointing this out here: http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1590
 2007-10-21 21:04:04 +00:00
ejcoumans e7caaa28d3 re-organized memory (stack and pool) allocators. this lets the user pass in their own memory allocators. 2007-10-20 02:23:39 +00:00
ejcoumans 1e4e52306f don't crash when running out of pool memory, just use btAlignedAlloc/btAlignedFree instead 2007-10-19 21:25:58 +00:00
ejcoumans dbe502c5a8 prepare for Box2D style gui demo 2007-10-18 06:37:36 +00:00

ejcoumans b5a498e8bf add get method for persistent manifold 2007-10-16 20:00:34 +00:00
ejcoumans 6303d98844 - use mfc directly, instead of cellDmaSmallGet (allow sizes under 32 bytes, instead of 16) 
- align btBroadphaseProxy to 16 bytes
 2007-10-16 00:52:23 +00:00
ejcoumans 23921729ea adding padding to broadphase proxy, to make it 16 bytes (helps some platforms to run) 2007-10-15 02:35:55 +00:00
ejcoumans ffcdb0f93d BulletMultiThreaded needs to refreshContactPoint for contact manifold (this has been moved to the collision detector, instead of constraint solver) 
BulletMultiThreaded support function for box shouldn't compensate for the collision margin anymore
 2007-10-14 01:51:07 +00:00
ejcoumans 913b141c23 fix some warning, need virtual destructor 2007-10-14 00:12:22 +00:00
ejcoumans 715611060d integrated StressTest into BasicDemo. 2007-10-14 00:03:10 +00:00
ejcoumans ea3dfb4ca3 made 'calculateLocalInertia' const, thanks to cgripeos, see http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1514 
- applied a large patch to remove warnings
Thanks to Enrico, see http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1568
- removed SSE includes, added #incude <string.h> for memset in Extras/quickstep, thanks Eternl Knight
- disabled 16-byte alignement on btQuadWord class, it causes problems under PS3 Linux. Need to check out why.
 2007-10-13 23:41:37 +00:00
ejcoumans 7a1e53935f make MSVC 6 compile, remove 'int i' out of the for loops 2007-10-12 06:34:01 +00:00
ejcoumans 62103c94de fixed growing of hash table, to avoid hard limit on overlapping pairs 2007-10-12 05:53:27 +00:00
ejcoumans eff4fe8ec8 more work on hashed pairmanager. growing doesn't work yet, so need to allocate enough room for the overlapping pairs in advance. 
boxbox reports contact point in B, rather then average point
box, cylinder use halfextents corrected for scaling and margin. made the margin in this halfextents explicit in the 'getHalfExtentsWithMargin' and 'getHalfExtentsWithoutMargin'
integrated changed for ODE quickstep solver
replaced inline with SIMD_FORCE_INLINE
some minor optimizations in the btSequentialImpulseConstraintSolver

added cone drawing (for X,Y,Z cones)
 2007-10-12 02:52:28 +00:00
ejcoumans 1baa61bc8d function isn't inline 2007-10-11 03:39:49 +00:00
ejcoumans 52eb5fa1a4 don't use multisap yet in basic demo. 
fix crash in multi sap (due to new pair manager)
 2007-10-11 03:32:37 +00:00
ejcoumans 0405ce278a use size_t instead of int, for allocator 
added hashtable based PairManager, thanks Pierre Terdiman and Erin Catto
improved friction in 'cachefriendly' solver
moved 'refreshcontactpoints' into collision detection, instead of solver
avoid linear search for contact manifolds, by storing an index
ignore margin for sphere shape (its entire radius is already margin)
avoid alignment checks in BVH serialization, they don't compile on 64-bit architectures
made 'bomb' box more heavy
 2007-10-11 03:17:54 +00:00
ejcoumans 118ac651dd updated IBM Cell SDK makefiles 2007-10-03 00:42:18 +00:00
ejcoumans 23a197b3dc add alignment for broadphase proxy/handle. need to benchmark this, and check it doesn't degrade the performance on other platforms. Otherwise make it conditional only when USE_LIBSPE2 is defined 2007-10-03 00:41:55 +00:00
ejcoumans 1d43b5ebae changed default stack size to 2 MB. This is still overly conservative probably. Need some deeper investigation on default memory sizes... 2007-09-30 04:43:34 +00:00
ejcoumans a98ccc839e enable double precision for triangle indices in BT_USE_DOUBLE_PRECISION mode (need to review this) 2007-09-30 02:28:04 +00:00
ejcoumans a38de566c6 make sure aligned structures/classes use the btAlignedAlloc/btAlignedFree, by overriding the operator new/delete for that struct/class. 
integrated some contributions from IBM Germany for libspe2
