GPU Cloth Simulation Pipeline in Lightchaser Animation Studio

Abstract

We present the simulation pipeline of character effects in Lightchaser Animation Studio and how we utilize GPU resources to accelerate clothing simulations. Many characters from ancient Chinese tales in our films are in complex costumes.(Figure 1) Such costumes contain five to six layers of fabrics, where several hundred thousand triangles are used to show the delicate folds of different cloth materials. At the same time, there are more than 600 similar shots bringing more than 1000 cloth simulation tasks in a film project. Therefore, the efficiency and accuracy of our cloth simulator is the key to the CFX production pipeline.
