Minor fixes (#ifndef SPU_COLLISION_OBJECT_WRAPPER_H block etc)
Only update 'setNumTasks' when necessary
Revert vectormath.h include (can't resolve conflicts with PS3 SDK, need additional #include path)

2d1777c899 Avoid collision detection/response between anchored (static) soft body cluster and a static/kinematic rigid body 2009-08-31 04:35:06 +00:00
erwin.coumans
2ef7c1a457 Fixes / improvements in soft body: 
avoid blow-up due to improper mass calculation for fixed nodes (happened when using clusters)
allow to create collision clusters for each tetrahedron or triangle, when using btSoftBody::generateClusters(0)
tweak soft body demos a bit, only draw debug wireframe if necessary

aef97d6015 Share btGjkPairDetector, btGjkEpa2, btVoronoiSimplexSolver with SPU/Multithreaded implementation (remove duplicate code) 
Make btTypedConstraint and btPersistentManifold both derive from btTypedObject to make SPU-side generic constraint solver easier.

Note: all build systems need to be updated: remove SpuVoronoiSimplexSolver.cpp, SpuGjkPairDetector.cpp, SpuEpaPenetrationDepthSolver.cpp, SpuGjkEpa2.cpp

3e2529fcb5 Minor constraint refactoring, to allow SPU-side processing for PLAYSTATION 3 (added non-virtual methods) 
Also comment-out some code for __SPU__ to reduce code size
Added btContactConstraint (only used on PS3 SPU right now, better to use btPersistentManifold directly for contact constraints)
Improved readblend utility library (see also usage in http://gamekit.googlecode.com with Irrlicht)

Fix for btConvexConvexAlgorithm, potential division by zero

40c73f327c + CMake build system fix under Windows: don't define _WINDOWS to allow Glut console demo to build properly 
+ Allow user to enable useConvexConservativeDistanceUtil . Use dynamicsWorld->getDispatchInfo().m_useConvexConservativeDistanceUtil = true;
(see Demos/Benchmarks/Benchmark4 (convex objects falling down)
+ Fix for plane drawing (just wire-frame)
+ Gimpact: use collision margin of 0.07 for demo (because BULLET_TRIANGLE_COLLISION is used)
+ replace dot,cross,distance,angle,triple in btVector3 by btDot, btCross,btDistance,btAngle,btDistance to avoid naming conflicts
+ Some fixes in GJK penetration depth normal direction (broken in a previous commit)
+ fix in calculateDiffAxisAngleQuaternion to make ConvexConservativeDistanceUtil work properly
+ allow debug drawing to debug btContinuousConvexCollision
+ add comment/warning that btTriangleMesh::findOrAddVertex is an internal method, users should use addTriangle instead

f552a1dbbf Remove first argument from btMultiSphereShape, calculate local inertia approximation from aabb. 
If user wants more accurate inertia tensor for multi-sphere shape, use btCompoundShape instead 
(amd btCompoundShape::calculatePrincipalAxisTransform)

6c80353556 Minor fix in friction: calculate second friction direction based on un-scaling first friction direction (issue if it was scaled to zero) 
Force activation state of static objects to be ISLAND_SLEEPING, once they are added to the world
Add backwards compatibility option btDiscreteDynamicsWorld::setSynchronizeAllMotionStates, just in case only updating active objects broke someones code

258ef6e25a + Added joint feedback for constraints, needs testing/demo before 2.75 release. 
See also http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=2677
and http://code.google.com/p/bullet/issues/detail?id=227

To enable, use constraint->enableFeedback(true);
And then either use
constraint->getAppliedImpulse() for an estimated applied impulse,
or constraint-> getAppliedLinearImpulse(), or constraint->getAppliedAngularImpulseA() or constraint->getAppliedAngularImpulseB().

+removed a few warnings.
