Global illumination in dynamic participating media is expensive, but in many applications interactivity is required. We use selective photon tracing to compute global illumination, which enables us to update mostly those photon paths that are affected by changes in the media. We enhance this technique by eliminating the need of shooting corrective photons,(More)
Volume rendering has been a relevant topic in scientific visualization for the last decades. However, the exploration of reasonably big volume datasets requires considerable computing power, which has limited this field to the desktop scenario. But the recent advances in mobile graphics hardware have motivated the research community to overcome these(More)
This paper proposes and compares several methods for interactive volume rendering in mobile devices. This kind of devices has several restrictions and limitations both in performance and in storage capacity. The paper reviews the suitability of some existing direct volume rendering methods, and proposes a novel approach that takes advantage of the graphics(More)
