Obscurance-based Volume Rendering Framework

Marc Ruiz, Imma Boada, Ivan Viola, Stefan Bruckner, Miquel Feixas, Mateu Sbert

INPROCEEDINGS, Proceedings of IEEE/EG International Symposium on Volume and Point-Based Graphics, Aug, 2008

Abstract

Obscurances, from which ambient occlusion is a particular case, is a technology that produces natural-looking lighting effects in a faster way than global illumination. Its application in volume visualization is of special interest since it permits us to generate a high quality rendering at a low cost. In this paper, we propose an obscurance-based framework that allows us to obtain realistic and illustrative volume visualizations in an interactive manner. Obscurances can include color bleeding effects without additional cost. Moreover, we obtain a saliency map from the gradient of obscurances and we show its application to enhance volume visualization and to select the most salient views.
