Abstract: Apparatus and method for encoding sub-primitives to improve ray tracing efficiency. For example, one embodiment of an apparatus comprises: a ray generator to generate a plurality of rays in a ray tracing graphics pipeline; a sub-primitive generator to subdivide each primitive of a plurality of primitives into a plurality of sub-primitives; a sub-primitive encoder to identify a first subset of the plurality of sub-primitives as being fully transparent and to identify a second subset of the plurality of sub-primitives as being fully opaque; and wherein the first subset of the plurality of primitives identified as being fully transparent are culled prior to further processing of each respective primitive.

Abstract: Apparatus and method for efficient graphics processing including ray tracing. For example, one embodiment of a graphics processor comprises: execution hardware logic to execute graphics commands and render images; an interface to couple functional units of the execution hardware logic to a tiled resource; and a tiled resource manager to manage access by the functional units to the tiled resource, a functional unit of the execution hardware logic to generate a request with a hash identifier (ID) to request access to a portion of the tiled resource, wherein the tiled resource manager is to determine whether a portion of the tiled resource identified by the hash ID exists, and if not, to allocate a new portion of the tiled resource and associate the new portion with the hash ID.

Abstract: Apparatus and method for more precise level-of-details transitions. For example one embodiment includes a graphics processor comprising: ray traversal hardware logic to traverse a ray through an acceleration structure to determine intersections between the ray and one or more object instances; and a level of detail selector to: set an instance comparison mask associated with an object instance to a first level of detail (LOD), the instance comparison mask comprising an N-bit value and one or more bits to indicate a type of comparison operation, compare a value from a ray mask with the N-bit value in accordance with the type of comparison operation to generate a comparison result, and determine whether to use the first LOD or a second LOD to render one or more pixels in accordance with the comparison result.
