d4698cb3d5 Added SoftBody demo, contribution by Nathanael Presson. Will integrate into Bullet broadphase. 
Added very basic drawTriangle for btIDebugDraw, useful for basic softbody visualization.
Added btGjkEpa2, contribution by Nathanael Presson. Improved version of EPA penetration depth computation, more suitable for multi-core/SPU (less memory usage). Note: btGjkEpa2 is not enabled by default currently.

eeb78b8d45 free memory for btShapeHulls, keep track of it in GL_ShapeDrawer. 
move btShapeHull and btConvexHull into its own library in Extras/ConvexHull (it allocates memory using mem/delete and refactoring into using btAlignedAlloc/Free takes too much time)
fix heightfield / btOptimizedBvh for quantization, so that raycast can use quantized aabb (clamp up for maxima and down for minima)

work-in-progress (update projectfiles etc)

a4e63aed00 - DemoApplication, debug text rendering was broken, glLoadIdentity() missing 
- copy user data over to child shape
- added applied impulse to btManifoldPoint
- add ContactProcessedCallback (needs test/demo)
- didn't copy over m_additionalDampingFactor into btRigidBody.

39ecc2ab7e error C2374: 'i' : redefinition; multiple initialization 
make MSVC 6.0 build again.
This code breaks:

for (int i=0;....
use
int i;
for (i=0;...
for (i=0;...
instead ;-)

dad6667756 Accidently moved gluLookAt in the GL_PROJECTION matrix, instead of GL_MODELVIEW matrix. 
Thanks Wol for reporting the issue.

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

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.
