Abstract:
In recent years, significant progress has been made in developing high-quality interactive methods for realistic volume illumination. However, refraction – despite being an important aspect of light propagation in participating media – has so far only received little attention. In this paper, we present a novel approach for refractive volume illumination including caustics capable of interactive frame rates. By interleaving light and viewing ray propagation, our technique avoids memory-intensive storage of illumination information and does not require any precomputation. It is fully dynamic and all parameters such as light position and transfer function can be modified interactively without a performance penalty.
