d3dc7afefd fix in non-SIMD OpenCL cloth demo, kernel names changed. 
Thanks Greg, see http://bulletphysics.org/Bullet/phpBB3/viewtopic.php?f=9&t=7442&p=25422#p25422

0656de3057 premake4 compile/link fixes 2011-09-16 19:56:14 +00:00
erwin.coumans
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

144d24009a CcdPhysicsDemo: fixed the setCcdMotionThreshold value, it was wrong (way too small 2011-09-15 23:24:42 +00:00

654fe7872a remove btContinuousDynamicsWorld, it is obsolete and was never completed.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
Thanks to Simon Lundmark for the suggestion

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

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)
