Abstract
A method renders a volume data set including a plurality of voxels. In the method, a). the volume data set is apportioned into a plurality of sections. Then, b). a first one of the plurality of sections is rendered by sequentially reading groups of voxels from an external memory and rendering the groups of voxels in the section. Then, c). any accumulated data from the rendering of the first one of the plurality of sections is stored in a temporary storage device. Then, a next one of the plurality of sections is rendered by sequentially reading groups of voxels of the next one of the plurality of sections from an external memory and rendering the groups of voxels, the rendering incorporating accumulated data from the temporary storage device, and then any accumulated data from the rendering of the next one of the plurality of sections is stored in the temporary storage device. Steps d and e are repeated until each of the plurality of sections of the volume data set have been rendered.
