1. An apparatus for rendering a volume data set including a plurality of voxels stored in a voxel memory, the apparatus comprising a plurality of pipelines operating in parallel, each pipeline comprising:

  • a buffer storing at least one block of at least two voxels of the volume data set;

    an interpolation stage reading the at least one block of at least two voxels from the buffer;

    a gradient estimation stage receiving an output from the interpolation stage;

    a compositing stage receiving an output from the gradient estimation stage; and

    a plurality of interface devices, each interface device coupling a particular stage only to an adjacent identical stage in a neighboring pipeline, the interfaces coupling identical stages in a ring.
