Position based dynamics

Definition

Position based dynamics is a fast, stable, and controllable simulation technique. It directly manipulates the vertex positions of object meshes instead of forces or impulses and can model various dynamic and interactive effects of objects such as rigid body, soft body, cloth, or fluids.

Introduction

Physically based simulation has been an important and active research field in computer graphics. In recent decade, it has become an indispensable component in movies, video games, or interactive applications. In addition, with the rapid growth of the computational capabilities of CPUs and GPUs, there are more and more demands for real-time complicated simulation effects.

The classic simulation method is based on Newton’s law of motion to accumulate internal and external forces acting on an object at the beginning of a time step. Then a numerical integration technique like explicit or implicit Euler integrator is further applied to estimate new...
