ab8f16961e Code-style consistency improvement:
Apply clang-format-all.sh using the _clang-format file through all the cpp/.h files.
make sure not to apply it to certain serialization structures, since some parser expects the * as part of the name, instead of type.
This commit contains no other changes aside from adding and applying clang-format-all.sh

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.

385933b5ed Expose the multi-point perturbation algorithm for btConvexPlaneCollisionAlgorithm
Usage:
	m_collisionConfiguration = new btDefaultCollisionConfiguration();
	m_collisionConfiguration->setPlaneConvexMultipointIterations();

It is only enabled for polyhedral convex shapes, because implicit/smooth surfaces such as spheres, cylinders, capsules and cones keep on rolling forever, due to the extra off-center contact points

fe6991822d Use the original code for convex-plane collision in (btConvexPlaneCollisionAlgorithm),
rather than the perturbed rotated version (it is slower and harder to debug)

0754876d77 Calculate multiple contact points (for convex-convex and convex-plane) when less then 3 points exist in the persistent manifold.
Uses the normal pertubation method, described by Gino van den Bergen:  http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=4&t=288&p=888#p888
Made btRigidBody::getInvInertiaDiagLocal const, thanks to abhikp (http://code.google.com/p/bullet/issues/detail?id=183 )

bcbe730471 Perform several rotation pertubations, to create multiple collision contact. works for convex versus plane. todo: convex versus convex.
See issue http://code.google.com/p/bullet/issues/detail?id=20:

Note that the default number of pertubation iterations (10) and pertubation angle (0.05) can be modified through the collisionConfiguration:

	btConvexPlaneCollisionAlgorithm::CreateFunc* func = (btConvexPlaneCollisionAlgorithm::CreateFunc*)collisionConfiguration->getCollisionAlgorithmCreateFunc(BOX_SHAPE_PROXYTYPE,STATIC_PLANE_PROXYTYPE);
	func->m_numPertubationIterations = 0;
	func = (btConvexPlaneCollisionAlgorithm::CreateFunc*)collisionConfiguration->getCollisionAlgorithmCreateFunc(STATIC_PLANE_PROXYTYPE,BOX_SHAPE_PROXYTYPE);
	func->m_numPertubationIterations = 0;

63dc666bf6 fix for static planeshape and spheres, need to use the getSupportingVertex with margin for proper contact point location. 2008-01-23 02:42:14 +00:00
