73b217fb07 Apple contribution for OSX SSE and iOS NEON optimizations unit tests, thanks to Jordan Hubbard, Ian Ollmann and Hristo Hristov. 
For OSX:
cd build
./premake_osx xcode4
for iOS:
cd build
./ios_build.sh
./ios_run.sh

Also integrated the branches/StackAllocation to make it easier to multi-thread collision detection in the near future. It avoids changing the btCollisionObject while performing collision detection.

As this is a large patch, some stuff might be temporarily broken, I'll keep an eye out on issues.

b5b31ce52b added VoronoiFractureDemo, thanks to RBD 
fix in infinite recursion in quickSort, exclude the pivot in each sub partition
disabled constraints don't merge simulation islands, and they don't disable collision between linked rigid bodies either.

a374f8c0d4 remove btOclGetMaxFlopsDev, it was buggy. Just use device 0 in the demos. The OpenCL initialization needs more work/some GUI. 2011-11-11 20:11:03 +00:00

1b305562be Added Pierre Terdiman's 'internal object' optimization to improve performance for separating axis tests. 
Make the winding consistent in btConvexHullComputer (and related fixes in btPolyhedralConvexShape), thanks to Ole!
Some fixes in the btPolyhedralContactClipping implementation (never report a penetration deeper than GJK/EPA found, to avoid issues due to its approximate contact normal directions)
Properly visualize btPolyhedralConvexHullShape that have a  btConvexPolyhedron (by calling initializePolyhedralFeatures() method)

9a9a4394ab fix in btParallelConstraintSolver to support double precision 
fixes in SAT/polyhedral contact clipping, avoid adding GJK contacts (the contact margin causes different contact depths)
add polyhedral convex shape in InternalEdgeDemo as example of the new SAT/polyhedral contact clipping (added reference to Manual/what's new)
avoid glueing objecs with contacts that are positive (no gaps)

ba5012973d Make argument to btDefaultSerializer optional, and use zero by default. This will dynamically allocate data, so there is no need to guess the maximum size anymore. 
Remove some cached data from SoftBodyLinkData, to reduce serialization file size.

6173a30bce Improved BulletSoftBody serialization, added cluster support. Joints and copying data from GPU back to softbody are the main todo. 
Updated the Bullet/Demos/SerializeDemo to load .bullet files with the softbody data.

BulletSoftBody should use getWorldTransform and not getInterpolationWorldTransform
Fix btBulletWorldImporter so that it creates a copy of the index/vertex data, this prevents crashes when deleting the .bullet file with triangle meshes.

032c6bfe2c add initial support for soft body / cloth serialization, and updated SerializeDemo to load soft bodies/cloth. 
Serializes soft body nodes (vertices), links, faces, tetrahedra, materials, anchors with rigid bodies.
Some todo's are serialization of pose, constraints between soft bodies
