abstract     : 

This paper presents an approach to collision detection
and response for dynamically deforming pointbased
objects. Both the volume of an object and its surface
are represented by point sets. In case of a collision, 
response forces are computed for penetrating surface
points and distributed to volume points which are used
for simulating the object dynamics. The decoupling of
collision handling and deformation allows for a very
stable collision response while maintaining interactive
update rates of the dynamic simulation for environments
with moderate complexity. Simulation results are presented
for elastically and plastically deforming objects with
changing topology.
