ejcoumans c86fea11dc use btHullShape/btConvexHull to reduce vertices in a convex hull. Perhaps we always use this, to avoid convex objects with too many vertices...? 2008-01-24 01:35:34 +00:00
ejcoumans 03a05c25af removing a lot of unwanted code from btConvexHull (more refactoring will follow) 2008-01-24 01:08:15 +00:00

ejcoumans f12f04fb97 optimization: only call solveGroup if there is some work: avoid virtual function call, its overhead can be excessive 
based on 3000 body benchmark

ejcoumans 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

ejcoumans 60fbf05a57 updated ChangeLog.txt, better to make a quick new release with the important fixes 2007-12-17 04:34:34 +00:00
ejcoumans 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.

ejcoumans 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.
