cf2337ed7b - Fixed a bug in btAxisSweep3 (sweep and prune) related to object removal. Only showed up when at least one btStaticPlaneShape was inserted. 
Thanks tbp for more details on reproducing case.
- Fixed issue with full 32bit integers in btAxisSweep3 (define BP_USE_FIXEDPOINT_INT_32), it used only 65536 for quantization, it should use full integer space (0xffffffff)
- Added 'getForwardVector' and getCurrentSpeedKmHour utility functions to btRaycastVehicle
- Fixed local scaling issues (btConvexTriangleMeshShape, btBvhTriangleMeshShape, removed scaling from btMatrix3x3). Thanks Volker for reporting!
- Added second filename search, so that starting BspDemo and ConvexDecompositionDemo from within Visual Studio (without setting the starting path) still works

82c8687881 - initialize m_unusedW to avoid some warnings. 
- added angularFactor to 'cachefriendly' constraint solver

2db8bfa3d6 Fix (needs more testing) in btRigidBody::setCenterOfMassTransform, assign m_interpolationWorldTransform = xform; instead of m_worldTransform; 
Thanks Jay for reporting
Added braking capability to btRaycastVehicle, see Bullet/Demos/VehicleDemo/VehicleDemo.cpp
Added glutKeyboardUpFunc, for vehicle demo (keep accelerating/breaking, until key released/UP). Hope this is compatible with most GLUT implementations.

9546633ade Added 'cache friendly' tree traversal format, and traversal. Array of subtrees with specified maximum size. This is useful to fit tree traversals on SPU. 2007-03-27 21:02:45 +00:00

c1a54d9edc Attempts to improve performance. Not much gain yet, but good to experiment what has effect and what hasn't. 
Added 'DO_BENCHMARK_PYRAMID' to CcdPhysicsDemo.

02e5f2dd8e void btDiscreteDynamicsWorld::solveConstraints(btContactSolverInfo& solverInfo) 
sortedConstraints.heapSort(btAlignedObjectArray<btTypedConstraint*>::less());

should be

sortedConstraints.heapSort(btSortConstraintOnIslandPredicate);
Thanks  	Clemens Unterkofler for pointing this out!

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

b73900bc60 Improved performance of convex collision shapes, cache local AABB instead of recomputation. This fixes issue with very slow performance in larger .bsp levels. 
Moved some asserts into 'btFullAssert', which is disabled by default (see btScalar.h to enable them). This is to speed-up debugging.

4d6ec84630 always update position, even for sleeping objects (is workaround, because sleeping objects never get their motionstate update), needs fixing for optimization 2007-02-14 04:02:14 +00:00

bf68a742cc by default, disable warmstarting, enable random ordering, 
user can override this using solver->setSolverMode(...)

e9b21e21a6 Pathnames between #include files that are intended to be used within application code should not depend on the paths to the subdirectories being known to the compiler because this will not always be the case when an end-user includes your headers. 
Includes of files in the local hierarchy must not use <...> please stick with "..."

208bbe7594 Added a set of empty, classless 'extern "C"' probe functions to allow '.so' loaders and application domain 'autotools' to easily and unambiguously check for the correct installation of the various bullet libraries. 
eg:

  bulletmath_suffix="-lbulletmath"
  bulletcollision_suffix="-lbulletcollision"
  bulletdynamics_suffix="-lbulletdynamics"
  dnl Check bulletmath library
  AC_CHECK_LIB(bulletmath, btBulletMathProbe, true,
  AC_MSG_ERROR([there seems to be a problem with the bulletmath library]))
  LIBS="$bulletmath_suffix $LIBS"
  dnl Check bulletcollision library
  AC_CHECK_LIB(bulletcollision, btBulletCollisionProbe, true,
  AC_MSG_ERROR([there seems to be a problem with the bulletcollision library]))
  LIBS="$bulletcollision_suffix $LIBS"
  dnl Check bulletdynamics library
  AC_CHECK_LIB(bulletdynamics, btBulletDynamicsProbe, true,
  AC_MSG_ERROR([there seems to be a problem with the bulletdynamics library]))
  LIBS="$bulletdynamics_suffix $LIBS"

bf591b44ec Replaced most STL std::vector with btAlignedObjectArray. 
Same interface but less features (push_back, pop_back, clear, size, [] etc).
To prepare for SIMD/SSE code: Added 		#define ATTRIBUTE_ALIGNED16(a) __declspec(align(16)) a

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)

6738ed329d ASSERT -> btAssert

56e135874b added angular limits to the Generic D6 constraint. Works for small angles. Will add a check for different combinations, and use different extraction of ordering of rotation from the diff quaternion. 
Improved vehicle interpolation of wheels, and added Z-up axis option for the Demo
made 'getWorldTransform' const method in btMotionState
added future 'deactivationCallback'(not used yet)
