Developing Simulation Techniques for an Interactive Clothing System

In this contribution towards creating interactive environments for garment design and simulation, we present a powerful mechanically based cloth simulation system. It is based on an optimized way to compute elastic forces between vertices of an irregular triangle mesh, which combines the precision of elasticity modelisation with the speed of a simple spring-mass particle system. Efficient numerical integration error management keeps computation speed efficient by allowing high computation timesteps and also maintains very good stability, suitable for interactive applications. Constraints, such as collisions or "elastics", are integrated in a unified way that preserves robustness and computation speed. We illustrate the potentialities of our new system through examples showing its efficiency and interactivity.
