Interactive visualization of multi-layered clothing

We present a non-iterative approach to visually plausible rendering of multi-layered clothes, aimed mainly at human figures dressed in multiple garments. The problems we address are cloth interference and z-fighting. Our approach is based on numbering layers of clothing and then using recursive ray tracing to keep them in order. Instead of developing a new physically based technique, such as collision detection/response schemes or particle systems, we develop a visualization technique to complement existing physically based methods, greatly reducing the required precision and, thus, the computational cost.
