This video shows an hybrid rendering method, aimed at providing medical-quality rendering of large medical datasets that do not fit into the graphics memory, in action. The hybrid approach takes advantage of the heterogeneity of the resources available on off-the-shelf computers: the large availability of system memory and the parallel-oriented architecture of modern GPUs. The CPU is used to render in high resolution a region-of-interest of the volume, whereas the GPU renders the context using a downsampled version of the dataset. The rendering method has been implemented as an extension of VTK, a widely used open source library, to promote its use and evolution.
