This is a collection of simple animated shorts I've created demonstrating basic modeling of physical forces and collisions. The modeling software was coded in C++ and each short demonstrates different aspects of the modeling process.
This models rigid bodies composed of individual particles and rigid body rotations.
This models continuous collision detection and hybrid collision response via iterative impulse application and the geometric method using impact zones to prevent tunneling during collisions. Programmed in C++. The clip below displays particle-particle, particle-edge, and particle-halfplane collisions with gravitational and spring forces.
This models basic gravitational forces between particles as well as spring forces between two particles connected by edge.
