摘要： A graphics processing subsystem and method for computing a 3D clipmap. One embodiment of the subsystem includes: (1) a renderer operable to render a primitive surface representable by a 3D clipmap, (2) a geometry shader (GS) configured to select respective major-plane viewports for a plurality of clipmap levels, the major-plane viewports being sized to represent full spatial extents of the 3D clipmap relative to a render target (RT) for the plurality of clipmap levels, (3) a rasterizer configured to employ the respective major-plane viewports and the RT to rasterize a projection of the primitive surface onto a major plane corresponding to the respective major-plane viewports into pixels representing fragments of the primitive surface for each of the plurality of clipmap levels, and (4) a plurality of pixel shader (PS) instances configured to transform the fragments into respective voxels in the plurality of clipmap levels, thereby voxelizing the primitive surface.

摘要： In various embodiments, a parallel processor implements a graphics processing pipeline that generates rendered images via a shading program. In operation, the parallel processor causes a first set of execution threads to execute the shading program on a first portion of the input mesh to generate first geometry stored in an on-chip memory. The parallel processor also causes a second set of execution threads to execute the mesh shading program on a second portion of the input mesh to generate second geometry stored in the on-chip memory. Subsequently, the parallel processor reads the first geometry and the second geometry from the on-chip memory, and performs operations on the first geometry and the second geometry to generate a rendered image derived from the input mesh. Advantageously, unlike conventional graphics processing pipelines, the performance of the graphics processing pipeline is not limited by a primitive distributor.

摘要： In various embodiments, a parallel processor implements a graphics processing pipeline that generates rendered images. In operation, the parallel processor causes execution threads to execute a task shading program on an input mesh to generate a task shader output specifying a mesh shader count. The parallel processor then generates mesh shader identifiers, where the total number of the mesh shader identifiers equals the mesh shader count. For each mesh shader identifier, the parallel processor invokes a mesh shader based on the mesh shader identifier and the task shader output to generate geometry associated with the mesh shader identifier. Subsequently, the parallel processor performs operations on the geometries associated with the mesh shader identifiers to generate a rendered image. Advantageously, unlike conventional graphics processing pipelines, the performance of the graphics processing pipeline is not limited by a primitive distributor.

摘要： In various embodiments, a deduplication application pre-processes index buffers for a graphics processing pipeline that generates rendered images via a shading program. In operation, the deduplication application causes execution threads to identify a set of unique vertices specified in an index buffer based on an instruction. The deduplication application then generates a vertex buffer and an indirect index buffer based on the set of unique vertices. The vertex buffer and the indirect index buffer are associated with a portion of an input mesh. The graphics processing pipeline then renders a first frame and a second frame based on the vertex buffer, the indirect index buffer, and the shading program. Advantageously, the graphics processing pipeline may re-use the vertex buffer and indirect index buffer until the topology of the input mesh changes.
