Abstract:

This paper introduces a practical shading model for cloth that can simulate both anisotropic highlights as well as the complex color shifts seen in cloth made of different colored threads. Our model is based on extensive Bidirectional Reflectance Distribution Function (BRDF) measurements of several cloth samples. We have also measured the scattering profile of several different individual cloth threads. Based on these measurements we have derived an empirical shading model capable of predicting the light scattered by different threads.We model cloth as a collection of threads in a weave pattern, which provides a description about the coverage of the different thread types as well as their tangent directions. Our model accounts for shadowing and masking by the threads. We validate our model by comparing predicted and measured values and we show how it can reproduce the appearance of different cloth samples with complex structure including silk, velvet, linen, and polyester. Our model is robust, easy to use, and it can model cloth types with complex highlights and color shifts that cannot be handled by previous models.
