Abstract
An apparatus and method for occlusion data compression. For example, one embodiment of a graphics processing apparatus comprises: vertex generation circuitry/logic to generate vertices of objects in a 3D space including occlusion binary vectors for the vertices, the objects captured by a set of M cameras; sorting circuitry/logic to sort the vertices in accordance with coordinates of the vertices; pre-compression circuitry/logic to transform the occlusion binary vectors of the vertices by logically combining adjacent bit fields in the sorted order to generate converted bit strings having a larger number of binary zero values than the occlusion binary vectors; compression circuitry/logic to compress the converted bit strings using run length encoding (RLE) compression to generate compressed bit fields; and a memory and/or storage device to store the compressed bit fields.
