Interactive Dynamic Volume Illumination with Refraction and Caustics

Jens G. Magnus, Stefan Bruckner

JOURNAL ARTICLE: IEEE Transactions on Visualization and Computer Graphics (in press), vol. 24, no. 1, 2018. DOI: 10.1109/TVCG.2017.2744438

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.
