- made getHeightFieldValue virtual (allows custom heightfield formats)
- don't use shorts, just full integers (no reason to limit the terrain size to 65536)
- optionally disable collisions between bodies that are linked with constraints
- improved debug rendering with support for compounds, spheres, capsules
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
Original aabb nodes are 44 bytes (with full floating point precision and additional part index)
- added meter-unit scaling support in ColladaConverter.cpp
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"
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
Added btStackAlloc to Bullet (right now only used by btGjkEpa)
removed default constructors of btCollisionWorld/btDiscreteDynamicsWorld, to reduce link-time dependencies
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
CompoundShapes are tricky to manage with respect to persistent contact points and swapped order of btCollisionObjects,
During dispatch, finding an algorith etc. order can be swapped.
fixed several other issues, related to SimpleBroadphase (removing a proxy was not working)
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
removed two cached optimizations, type in btTransform and cached inverse transform (todo: test performance impact)
committed fixes that make the code adhere to 'who creates it, also destroys it'
