Strong Constraint Dynamic Simulation Method for 3D Garment Models

Abstract

With the continuous improvement on quality of 3D games and virtual fitting, the trend of garment simulation has changed from the cloth simulation to the dynamic simulation. Garment simulation is of significantly theoretical and practical value, because it is authentic, real-time, universal and interactive. To solve the problems commonly existing in present algorisms on timeliness, universality and over-stretching, a real-time simulation method for all 3D garment models was proposed. In this method, the triangle faces were mapped to the mass-spring model, which overcame the restriction effect of the traditional solver on cloth regular grid. The Verlet integrator is easy to improve the computation efficiency. And the authors put compensation on confrontation of deformation constraint, which prevented the over-stretching and improved the stability of the system. The efficiency and reliability of the proposed algorithm was verified by experiments. The experiment results show that this algorithm is simple and easy to operate, and it can be easily integrated in the form of plug-in components and modules with other software.
