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

bb29d15058 create premake4 solutions for the various OpenCL configurations (AMD, NVIDIA, Intel OpenCL SDKs for Windows) 
primarily to distribute project files that work.
CMake is still better supported in general (not all demos/libs have been ported)

654fe7872a remove btContinuousDynamicsWorld, it is obsolete and was never completed. 
If you need tunneling prevention, one option is to use the CCD motion clamping in btDiscreteDynamicsWorld. See also Bullet/Demos/CcdPhysicsDemo.
You can use an embedded sphere that prevents tunneling, using the following settings:

		body->setCcdMotionThreshold(0.5);
		body->setCcdSweptSphereRadius(0.9f);


Add a camera zoom setting for the demos, thanks to ejtttje, fixes Issue 543

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
