Using visual particles to solve the collision in textile simulation
采用虚拟粒子解决织物仿真中的碰撞问题

Particle systems that adaptively generate new particles was introduced, wherever this was required to model collisions correctly. When coarse meshes collide with an object they were automatically refined. Therefore this model allows physically accurate simulations that require a much smaller number of particles than regular particle systems. It is also possible for fast simulations with coarse meshes.
