Abstract
This thesis presents a collision contact modeling method in a virtual reality environment, Virtual Assembly Design Environment (VADE), where the rigid bodies are represented by a great number of triangle meshes. Unlike traditional colliding contact simulations, which need the surface information of rigid bodies for collision detection, the challenge of adoption of triangle meshes representation is the lack of such surface information. RAPIDTM (a collision detection package) is used to obtain the approximate collision contact information. By introducing impulse, the collision contact modeling is integrated into the previous dynamic simulation modules (free motion in space and motion constrained by a fixed axis or a plane) in VADE. An approximated method named threepoint method is used to determine the final resting location of a moving object. An eventdriven modeling is presented to manage the interaction process for dynamic simulation. A series of test cases have been presented and analyzed to prove the usability of the existing dynamic simulation modules with the new collision contact modeling method integrated.
