Virtual Simulation of Dynamic Interaction of Deformable Objects

Abstract. Collision response analysis is one of the most crucial parts in dynamic simulation of deformable objects. In the past, researchers proposed many solutions to this task. Miller presented a position based dynamics framework that handles general constraints, and Shinar developed a full two-way coupling of rigid and deformable bodies. Lenoir and Fonteneau used Lagrange multipliers to model two-way interaction with a limitation to analytical deformable objects. The main purpose of this work is to propose a new algorithm for the collision response analysis, which is accurate in terms of description of collision response, general-purpose in terms of no extra assumptions on geometric constraint formula, nodal connection at contact surface, deformation zones, etc., and yet fast in terms of guaranteed O(n) time cost.

Keywords. Deformable Object, Dynamic Interaction, Virtual Simulation
