computer animation, physically-based modeling, single particles
Physically based modeling is a growing trend in computer animation. There are many implementations available for this topic. The most basic of these involves the movement of single particles (without a shape) moving through space. This implementation involves the movement of particles that have a rigid structure, such as a box or ball, known as rigid bodies. It features a simple box comprised of 8 points moving through space according to the laws of physics as it makes contact with a surface.
