 2012-12-17 21:29:20 +00:00
erwin.coumans 7e14e79da0 Fix Issue 680, compilation error using Visual Studio 2005, service pack 1, quicksort compare function needs to be in a class.

 2012-12-17 20:38:31 +00:00
erwin.coumans c4548ec746 Add a helper method that creates a btCompoundShape from a btGimpactMeshShape, for more robust collision detection. 
The idea is to create tetrahedra from each surface triangle, by moving its centroid inwards along the collision normal using depth.
If the centroid hits an internal triangle, it will stop there.

The commit also includes part of the gimpact raycast performance improvement, except for the actual btCollisionWorld part
(that file was out-of-date and needs manual patching)
 2012-12-14 23:14:09 +00:00
erwin.coumans 27fd8ea0d7 make it more obvious that btBvhTriangleMeshShape cannot be used for moving objects. 2012-12-14 20:31:03 +00:00
erwin.coumans 1d4a5d950d Usually m_contactNormal2 == -m_contactNormal1, but not always, so 
use a separate contactNormal1/contactNormal2 for each body in btSolverConstraint.

Thanks to Richard McDaniel for the patch.

erwin.coumans c4db79791c Improve the loading of serialized Bullet files, so that 
after 'loadFileFromMemory' you can save the existing memory back to disk converted to native architecture endianness.
Fixed a bug that prevented big endian machines to load cloth data (due to wrong endian swap of pointer array)
Also improved the 'preswap' so that you can swap endianness on big endian machines (to little endian)
