Abstract
The present embodiments relate to presampled photon maps for Monte-Carlo volume renderings. A photon map is generated from scan data of a volume, and the photon map is sampled and stored as an O-buffer or a uniform buffer. The O-buffer is adapted to the scan data and/or the transfer function to optimize the offset of the O-buffer for use in Monte-Carlo volume rendering. A Monte-Carlo volume rendering is generated from the scan data and the sampled photon map.
