At least one processor may organize a plurality of primitives in a hierarchical data structure. The at least one processor may rasterize a plurality of bounding volumes associated with non-root nodes of the hierarchical data structure to an off-screen render target. The at least one processor may determine a bounding volume that is intersected by a ray out of the plurality of bounding volumes. The at least one processor may determine a non-root node of the hierarchical data structure that is associated with the bounding volume as a start node in the hierarchical data structure to start traversal of the hierarchical data structure. The at least one processor may traverse the hierarchical data structure starting from the start node to determine the primitive that is intersected by the ray.

The invention is system and method to recognize speech vocalizations using context-specific grammars and vocabularies. The system and method allow increased accuracy of recognized utterances by eliminating all language encodings irrelevant to the current context and allowing identification of appropriate context transitions. The system and method creates a context dependent speech recognition system with multiple supported contexts, each with specific grammar and vocabulary, and each identifying the potential context transition allowed. The system and method also include programmatic integration between the context dependent speech recognition system and other systems to make use of the recognized speech.

This disclosure describes a method for performing conservative rasterization in a processor comprising determining vertices of a primitive, defining edges of the primitive by determining a set of edge equations based on the determined vertices, wherein the edge equations are based on an edge shifting parameter plus an offset, determining pixels that touch the edges of the primitive using the determined edge equations, and rasterizing the primitive using the determined pixels.
