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

8b849e0d07 Fixed split impulse SIMD issue in the constraint solver (doesn't affect default behaviour, as split impulse is switched off by default)

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)

Revert a recent change about warnings: %zu doesn't work in printf, %d does

654fe7872a remove btContinuousDynamicsWorld, it is obsolete and was never completed.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

69a932f13e Choose a default 'safe' collision margin for very small convex collision shapes, in particular btBoxShape and btCylinderShape 
and add some documentation in btConvexInternalShape.h

b68c64f2db Disable DX11 cloth bounds update, it is too slow by default. 
Use g_dx11Solver->setEnableUpdateBounds(true); to re-enable it (it enables GPU collision of cloth versus capsule)

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)

251bb4e727 remove the 'exit' calls from the OpenCL soft body solver. Use the solver->checkInitialized() method, after solver->optimize() to see if the kernels build OK. 2011-06-30 00:23:42 +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)
