Branches : master
Author : Erwin Coumans (erwin)
----------------------------------------
Hi there, it has been a while, just curious if my SVN account still works :)
This commit is an attempt to improve collisions between moving Bullet rigid bodies using (concave) triangle mesh bounds.
Instead of using Gimpact, this we create a btCompoundShape with child shape tetrahedra derived from the surface triangles.
For each triangle, we add a fourth vertex using the centroid, shifting inwards using the triangle normal.
If the centroid hits an internal triangle, we stop. The default depth could be exposed as 'advanced' setting in the user interface.
This solution will be a slower than the original/gimpact solution, but a bit more reliable.
In the future, it is better to add HACD, convex decomposition to Blender, for moving concave meshes.
See http://kmamou.blogspot.com and the Bullet SDK's Demos/ConvexDecompositionDemo.

Author : Erwin Coumans (erwin)
----------------------------------------
Bugfix for #26795 and #26917, Fix a bug that cause the radar sensor to break
Never memset(&ob, 0,sizeof(class)) when there is a constructor, it overrides all memory.
The problem was that the memset(0) was setting the scaling to (0,0,0), the height of the cone became 'infinity'
so GJK would iterate 'MAX_ITER' without converging due to this #NAN value

Author : Erwin Coumans (erwin)
----------------------------------------
cmake fix for Windows: link OpenCollada <libraryname>_d.lib in debug builds and <libraryname>.lib in release builds
this prevents crashing at startup of Blender in debug builds with cmake.

See bugreport by Andrea in the mailinglist here:
http://www.mail-archive.com/bf-committers@blender.org/msg00668.html

Also enabled WITH_OPENCOLLADA in cmake by default so the feature gets tested. If other devs like to keep OpenCollada it disabled, please revert the ON to OFF again.
