Abstract

Realistic modeling and high-performance rendering of cloth and
clothing is a challenging problem. Often these materials are seen
at distances where individual stitches and knits can be made out
and need to be accounted for. Modeling of the geometry at this
level of detail fails due to sheer complexity, while simple
texture mapping techniques do not produce the desired quality.

In this paper, we describe an efficient and realistic approach
that takes into account view-dependent effects such as small
displacements causing occlusion and shadows, as well as
illumination effects. The method is efficient in terms of memory
consumption, and uses a combination of hardware and software
rendering to achieve high performance. It is conceivable that
future graphics hardware will be flexible enough for full
hardware rendering of the proposed method.
