f12f04fb97 optimization: only call solveGroup if there is some work: avoid virtual function call, its overhead can be excessive

15cdd9de8e Rename btCollisionWorld::convexTest to btCollisionWorld::convexSweepTest. The new test sweeps the convex shape against all objects in the world taking into account the orientation specified in the from and to transformations. 2008-01-11 20:18:29 +00:00

d051e2eacb First commit of 2008, Happy New Year! 
Add option to compile without btClock and without profiling: comment out USE_BT_CLOCK, and #define BT_NO_PROFILE
Fixed typo/case in #include "LinearMath/btQuickProf.h", in SpuParallelSolver.cpp
Removed unnecessary files from libxml CMakeLists.txt

17a214a2b3 - Added btRigidBodyConstructionInfo, to make it easier to set individual setting (and leave other untouched) during rigid body construction. 
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.

947dc8d33d Moved the 'btRigidBody::clearForce' to the end of the stepSimulation, instead of in each substep. 
Should help with this issue, reported here: http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1601
We can optionally leave out the 'clearForces'.
Thanks everyone for the discussion.

7ef4eab189 use better tolerance, instead of hard-coded 0.0001 inside the btMultiSphereShape supporting vector implementation. 
Thanks to Phil Knight for reporting and fixing this issue (it could lead to failing collisions under certain conditions).
