摘要： A technique for compressing an original image is disclosed. According to the technique, an original image is obtained and a delta-encoded image is generated based on the original image. Next, a segregated image is generated based on the delta-encoded image and then the segregated image is compressed to produce a compressed image. The segregated image is generated because the segregated image may be compressed more efficiently than the original image and the delta image.

摘要： A technique for performing ray tracing operations is provided. The technique includes traversing through a bounding volume hierarchy to an instance node; performing an instance node transform using common circuitry; traversing to a leaf node of the bounding volume hierarchy; and performing an intersection test for the leaf node using the common circuitry.

摘要： A technique for performing a ray intersection test, the method comprising: receiving a request for an early termination ray intersection test for a ray; testing the ray against one or more early termination box nodes and one or more normal box nodes of a bounding volume hierarchy; and based on the test of the ray against the one or more early termination box nodes, determining whether to end traversal of the bounding volume hierarchy and determine whether the ray intersects geometry for the purpose of the ray intersection test.

摘要： A technique for performing ray tracing operations is provided. The technique includes receiving a ray for an intersection test, testing the ray against boxes specified in a bounding volume hierarchy to eliminate one or more boxes or triangles from consideration, unpacking a triangle from a compressed triangle block of the bounding volume hierarchy, the compressed triangle block including two or more triangles that share at least one vertex, and testing the ray for intersection against at least one of the unpacked triangles.

摘要： Techniques for performing shader operations are provided. The techniques include, performing pixel shading at a shading rate defined by pixel shader variable rate shading (“VRS”) data, and updating the pixel VRS data that indicates one or more shading rates for one or more tiles based on whether the tiles of the one or more tiles include triangle edges or do not include triangle edges, to generate updated VRS data.

摘要： A technique for performing ray tracing operations is provided. The technique includes reading descendant-shared type metadata for a non-leaf node of a bounding volume hierarchy; identifying one or more culling types for a ray-intersection test for a ray; and determining whether to treat the non-leaf node as not intersected based on whether the one or more culling types includes at least one type specified by the descendant-shared type metadata.
