Physically based animation Final Project Proposal

Implementation of multiple point collisions between rigidbodies.

This is an extension of my rigid body dynamics program to include the following:

1)Edge-Edge collisions between 2 objects.

2)Collisions between 2 objects at multiple points of contact.

Possible effects that could be generated using this framework are landslides,pinball,etc.

2)Complementarity Based Multiple Point Collision Resolution. - T.Giang,G.Bradshaw,O.Sullivan

3)Nonconvex Rigid Bodies with Stacking - E.Guendelman,R.Hridson,R.Fedkiw

If time permits possible extensions could be:

1)Implementation of impulse based resting contacts and stacking.

2)Implementation of shadows using the openGL stencil buffer.
