A new numerical integration method using trapezoid formula for 3D virtual clothes animation

摘要

Dynamics-based 3D virtual clothes animation has a great application prospect in textiles, animation, and E-commerce. However, because of its large amount of calculation in clothes simulation, the current PC is still difficult to achieve real-time requirement, especially the numerical integration is rather time-consuming, leading to clothes animation have not been widely applied in real life. To further accelerate the performance of numerical integration for clothes animation, this paper proposed an improved method based on the Trapezoid formula using the Verlet algorithm. The simulation results show that the proposed method can increase almost two times overall performance for 3D virtual clothes animation.
