9ad17dda22 Add aabbMin/aabbMax to broadphase proxy, and improve rayTest performance.
Todo: use broadphase acceleration structure (btDbvtBroadphase etc) for ray test

2b71784c86 Make getShapeType() a non virtual function.
Add localGetSupportVertexNonVirtual, localGetSupportVertexWithoutMarginNonVirtual, getAabbNonVirtual and getMarginNonVirtual methods to convex shape classes

1c0fa00bc7 + provide access to 'root' collision shape, in case the original collision shape is temporarily replaced by a child collision shape.
+ added MultiMaterialDemo showing how to use the new btTriangleIndexVertexMaterialArray.
Thanks to Alex Silverman for this contribution!

b66e5350d0 rename HasHit method to hasHit

bd97c5e569 Fixed warnings in Bullet/src core library
Thanks Martijn Reuvers from Two Tribes B.V. (www.twotribes.com) for the patch

To make this work more visible, suppress warnings in external libraries in Extras (COLLADA_DOM, libxml and glui contain many warnings)
Added PreprocessorDefinitions: _CRT_SECURE_NO_DEPRECATE;_CRT_NONSTDC_NO_DEPRECATE to vcproj files

b37a37a28e Added initial broadphase support for softbody versus softbody and softbody versus rigidbody (see btSoftSoftCollisionAlgorithm and btSoftRididCollisionAlgorithm)
Added 	SOFTBODY_SHAPE_PROXYTYPE.
Some refactoring for btSoftBody, needs more work.

65bb612598 - added quickSort to btAlignedObjectArray (has generally better performance then heapSort)
- replaced all usage of heapSort by quickSort
- finished btMultiSapBroadphase. Still some work to be done to increase performance (faster add/remove from child broadphases. 
  uses currently AABB tree to locate child broadphase (should use grid), and sorted array takes too much time.

fe5386a5c8 Made the move from sourceforge to googlecode (no svn sync any longer)
Fixed BulletColladaConverter load/save

6303d98844 - use mfc directly, instead of cellDmaSmallGet (allow sizes under 32 bytes, instead of 16)
- align btBroadphaseProxy to 16 bytes

23921729ea adding padding to broadphase proxy, to make it 16 bytes (helps some platforms to run) 2007-10-15 02:35:55 +00:00

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

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)

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

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

1f7646f72a Refactoring to enable multi SAP broadphase.
This was already planned, and Pierre Terdiman recent thread motivated me to decouple the paircache from the sweep and prune.

177b6f5ce2 Added btUniformScalingShape (including support for debug rendering etc)
This allows to re-use a convex shape, while each instance can re-scale it (with a uniform scalar factor)

685138d033 include paths should not be relative starting with "../
It leads to problems with certain compilers, when Bullet/src is located in a long pathname.
Keep include path starting with "LinearMath/, "BulletCollision/, or "BulletDynamics/

054d672592 - removed STL from the Bullet library: replace std::vector by btAlignedObjectArray. Also removed the std::set for overlapping pair set, and turned it into an overlapping pair array. The SAP only adds objects, never removed. Removal is postponed for during traversal of overlapping pairs (duplicates and non-overlapping pairs are removed during that traversal).
- added heap sort and binary search/linear search to btAlignedObjectArray
- fixed wrong cast, thanks Hamstray, http://www.continuousphysics.com/Bullet/phpBB2/viewtopic.php?t=1015

581468ceec Added btCapsuleShape. This could already be simulated by simply adding 2 spheres to the btMultiSphereShape, but this was bad documented/unknown.
For tapered capsules, you can still use btMultiSphereShape, just pass 2 spheres with different radius.

b6d1b4c94e Added btNearCallback. This is similar to Open Dynamics Engine (ODE) dNearCallback, but important differences:
- contact points are persistent (lifetime more then one frame, for warmstarting/incremental contact point management)
- continuous collision detection, time of impact
Added btRigidBody::isInWorld(), returns true if btRigidBody is inside a btCollisionWorld/btDynamicsWorld derived class
Added angularFactor to btRigidbody, this helps some character control (no angular impulse applied)

3fe3b11924 use Dispatcher in ConcaveConvexCollisionAlgorithm (so it uses the registered collision algorithm, not hardcoded convexconcave)
improved performance of constraint solver by precalculating the cross product/impulse arm
added collision comparison code: ODE box-box, also sphere-triangle
added safety check into GJK, and an assert for AABB's that are very large
write partid/triangle index outside of GJK

323a1046fd Cleaned up/simplified construction of a btRigidBody
Fixed memoryleak in btOptimizedBvh (delete []m_contiguousNodes;)
Changed DemoApplication::localCreateRigidBody, so it adds the rigidbody to the btDynamicsWorld.
Added check for duplicate objects in world when adding.
Added assert to prevent setLinearVelocity on static rigidbodies
Added btCollisionFilterGroups to btBroadphaseProxy
removed duplicate 'btBroadphaseProxy*	m_broadphaseProxy;' in btRigidBody

eb23bb5c0c merged most of the changes from the branch into trunk, except for COLLADA, libxml and glut glitches.
Still need to verify to make sure no unwanted renaming is introduced.

0e04cfc806 First stage in refactoring Bullet: moved Bullet Collision and Dynamics and LinearMath into src folder, and all files in Collision Detection and Dynamics have bt prefix.
Made all buildsystems to work again (jam, msvc, cmake)
