Real-time simulation of soft-object dynamic deformation

在计算机动画和虚拟现实技术中,基于物理的建模方法是高真实感地模拟物体受力变形和运动的有效途径,用简化的质点-弹簧模型具有物理真实感地动态的模拟柔软物体变形过程。质点的运动满足拉格朗日运动方程,采用了微分方程组来表示质点的运动规律,同时还将一个简单的柔软物体碰撞处理方法应用在质点-弹簧模型中,实验结果表明该方法是简单有效的。

In the computer animation and virtual reality applications, physically based modeling is an effective method for soft object deformation and movement simulation. The physically realistic deformation is simulated by using a simplified mass-spring model. The mass movement meet Lagrange＇dynamics equation. A differential equations is adopted to express the movement of particles, and numerical solution of the system of real time computation is used, which increased efficiency. At the same time a simple soft-objects collision approach is applied to mass-spring model, the experiment shows that the method is simple and effective.
