dcfb23dc13 update build for btConvex2dShape functionality 
use btDbvtBroadphase in HelloWorld demo, it is the recommended broadphase
 2009-09-17 20:17:14 +00:00
erwin.coumans
f65e829ca0 Add support for generic 2d convex shapes, through wrapper class btConvex2dShape. See Bullet/Demos/Box2dDemo for example wrapping a btCylinderShape and 2d btConvexHullShape. 
Add some extra degeneracy debugging check in btGjkPairDetector

3da9c832ae Initialize the world transform to identity for btCollisionObject/btRigidBody. 
Some developers only initialize the world position, and not the orientation -> uninitialized data. 

We should probably add some warning in btTransform, in debug mode. Note we don't initialize btTransform/btQuaternion/btVector3/btMatrix3x3 default constructor, for performance reasons.

49a0b479c6 Switch off an optimization by default, to avoid support burden: update all objects AABBs and not just the active objects. 
Call world->setForceUpdateAllAabbs( false) to re-enable the optimization: it will only update active objects (skipping static geometry)

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

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
