Abstract:
Systems and methods of geometry processing, for rasterization and ray tracing processes provide for pre-processing of source geometry, such as by tessellating or other procedural modification of source geometry, to produce final geometry on which a rendering will be based. An acceleration structure (or portion thereof) for use during ray tracing is defined based on the final geometry. Only coarse-grained elements of the acceleration structure may be produced or retained, and a fine-grained structure within a particular coarse-grained element may be Produced in response to a collection of rays being ready for traversal within the coarse grained element. Final geometry can be recreated in response to demand from a rasterization engine, and from ray intersection units that require such geometry for intersection testing with primitives. Geometry at different resolutions can be generated to respond to demands from different rendering components.

Claim (Index 9):
A graphics rendering system for geometry processing for 3-D rendering, the system configured to:\n produce geometric primitives located in a 3-D scene from source geometry data; define a set of tile object lists, wherein each tile object list contains data indicating which source geometry from the set of source geometry results in geometric primitives that are within a boundary of a respective tile of pixels of a 2-D image; produce an acceleration structure comprising a graph of elements, each defining a respective volume in the 3-D scene; and render the 2-D image from the scene by:\n using the tile object lists to identify a visible surface at each pixel of the 2-D image, and \n tracing rays in the 3-D scene, using the acceleration structure, from the identified visible surfaces to identify a primitive intersected by each of the rays, if any, producing information contributing to a final shade for the visible surface at each pixel.
