VARIABLE RATE TESSELLATION - A simplified explanation of the abstract
- This abstract for appeared for patent application number 17658634 Titled 'VARIABLE RATE TESSELLATION'
Simplified Explanation
This disclosure describes a system and method for variable rate tessellation in computer graphics. The system includes a graphics processor that receives data for processing a group of patches in a draw call. The graphics processor adjusts the tessellation factor of each patch based on its specific properties, such as shading rate or number of visible pixels. This adjusted tessellation factor is referred to as TRF. The graphics processor then applies the TRF to each patch and renders them accordingly.
Original Abstract Submitted
This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for variable rate tessellation. A graphics processor may receive data for geometry processing of a plurality of patches in a draw call. The graphics processor may reduce a tessellation factor of each of the plurality of patches based on a property of each of the plurality of patches. The reduced tessellation factor may correspond to a TRF. The property may correspond to a shading rate or a number of visible pixels. The graphics processor may apply the TRF for each of the plurality of patches. The graphics processor may render each of the plurality of patches based on the applied TRF for each of the plurality of patches.
