Colored Stochastic Shadow Mapping for Direct Volume Rendering

Abstract

Creating direct volume renderings with shadows can lead to a better perception of the rendered images. Deep shadow maps is an effective and efficient approach to compute shadows at interactive rates. We propose an alternative approach based on colored stochastic shadow maps (CSSM), which can produce higher-quality colored shadows while using less texture memory. CSSM is based on a stochastic generation of the shadow map, which is queried multiple times for denoising during rendering.
