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
This was harder using default arguments. Thanks Vangelis Kokkevis for pointing this out.
- Fixed memoryleak in the ConstraintDemo and Raytracer demo.
- fixed issue with clearing forces/gravity at the end of the stepSimulation, instead of during internalSingleStepSimulation.
Thanks chunky for pointing this out: http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1780
- Disabled additional damping in rigid body by default, but enable it in most demos. Set btRigidBodyConstructionInfo m_additionalDamping to true to enable this.
- Removed obsolete QUICKPROF BEGIN/END_PROFILE, and enabled BT_PROFILE. Profiling is enabled by default (see Bullet/Demos/OpenGL/DemoApplication.cpp how to use this).
User can switch off profiling by enabling define BT_NO_PROFILE in Bullet/src/btQuickprof.h.
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
Some dynamic memory allocations have been replace by pool allocation or stack allocations.
quantized aabb versus quantized aabb overlap check is made branch-free (helps a lot on consoles PS3/XBox 360)
Collision algorithms are now created through a new btDefaultCollisionConfiguration, to decouple dependency (this is the API change):
Example:
btDefaultCollisionConfiguration* collisionConfiguration = new btDefaultCollisionConfiguration();
m_dispatcher = new btCollisionDispatcher(collisionConfiguration);
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
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)
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'
