Using Particles for Footprints and Body Interactions With Ground


Interactions with sand in "Madagascar" (due to feet or bodies) had to leave impressions. The footprint system semi-automates footprint data generation and saves enough additional information for further variations.

Implementation of Fast Frictional Dynamics for Rigid Bodies


Implementation Sketch


This sketch presents some important details that went into implementation of our Fast Frictional Dynamics algorithm. The goal is fast simulation of large sets of non-convex rigid bodies. This sketch discusses the implementation details underlying the SIGGRAPH 2005 Paper: Fast Frictional Dynamics for Rigid Bodies.
