APPARATUS AND METHOD FOR VOLUME RENDERING ON MULTIPLE GRAPHICS PROCESSING UNITS (GPUs)

摘要

A method for volume rendering a volumetric dataset with multiple graphics processing units (GPUs) coupled to a computer system, comprises building a block hierarchical structure of blocks for the volumetric dataset, the block hierarchy comprising a block sequence; partitioning the block sequence into a plurality of groups; determining a target work load for each GPU; allocating each group of the plurality to a respective GPU in accordance with the target load; rendering respective intermediate images by the respective GPUs; and compositing for a final image by blending the respective intermediate images.
