1. A volume rendering system for enabling parallel-pipeline processing of perspective rays cast into a volume to be rendered by parallizing perspective rays, comprising:

  • a memory for storing plural voxels, said voxels collectively describing said volume to be rendered;

    a resampling unit for selectively receiving a subset of said voxels from said memory, said subset of said voxels proximate to a sample along a particular ray, and for combining said subset of voxels into said sample;

    a rendering module for receiving said sample and for selectively combining said sample with other samples along said particular ray received from said resampling unit to generate a single pixel centered on said particular ray; and

    a perspective ray control element, in communication with said memory, said resampling unit, and said rendering module, for casting said particular ray through said single pixel.
