Abstract: Translucent volume rendering is a robust and efficient direct volume-rendering technique for capturing optical effects, like\nsubsurface scattering, translucency, and volumetric shadows. However, due to the limited computing and memory resources of\nthe recent consumer graphics hardware, high-resolution volume data can still hardly be interactively visualized by this method.\nIn this paper we present the theoretical aspects and implementation details of a parallelization scheme for translucent volume\nrendering. Our method is a three-pass parallel rendering algorithm with parallel compositing, based on object-space distribution\nof the data among the rendering nodes. In the first pass the 2D shadow maps are computed and sent to the effected nodes. In the\nsecond pass the nodes render their associated subvolumes by sequential translucent volume rendering. The generated framelets\nare then visualized by a dedicated display node in the third pass.
