Add per-triangle collision information for physical properties lookup (friction, restitution etc) #3

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 

Feature information / callback mechanism will be added, and per-contact 
point friction/restitution too.

Some functionality in the BVH tree is already prepared for this.

Per-triangle friction/restitution requires a callback implementation. This 
callback 
can store the friction and/or restitution in the contact point.

Each CollisionObject that needs this material-callback has to set the 
collisionFlag 
to ccdObjectCi.m_collisionFlags = CollisionObject::customMaterialCallback;

See ConcaveDemo for an example, in particular CustomMaterialCombinerCallback.
