Claim 9:
10. A system for performing accelerated volume rendering of a scene in a computer system, said system comprising:
a system memory for storing volume data;
a processor device operatively coupled with the system memory configured to:
partition a three-dimensional description of a scene containing volume data into layers, each layer having an associated light field and at least one slab volume, each slab volume having an associated hogel subset such that all rays associated with the hogel subset intersect the slab volume;
volume render the light field associated with each layer using the volume data contained within each layer such that volume rendering calculations are performed for rays in the hogel subset and volume rendering calculations for each hogel subset are synchronized as rays associated with each hogel subset intersect the slab volume to provide rendered light fields;
cache the volumetric light field data intersecting the corresponding slab volume and storing the volumetric light field data in a local store cache memory; and
blend the rendered light fields associated with each layer into a single output light field image.
