1. TJHSST Systems Lab Rigid Body Dynamics Simulation
Eugene Paik

2. Introduction What is rigid body dynamics?
In physics, rigid body dynamics is the study of the motion of rigid bodies. (wikipedia)
What is my project about?
My project focuses on accurately graphically simulating these physical interactions between rigid bodies.

3. Applications
