Detailed Description

btShapeHull implemented by John McCutchan.

The btShapeHull class takes a btConvexShape, builds a simplified convex hull using btConvexHull and provides triangle indices and vertices. It can be useful for to simplify a complex convex object and for visualization of a non-polyhedral convex object. It approximates the convex hull using the supporting vertex of 42 directions.
