DENSITY DRIVEN VARIABLE RATE SHADING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17816362 titled 'DENSITY DRIVEN VARIABLE RATE SHADING

Simplified Explanation

The abstract describes methods and devices for graphics processing, specifically related to an apparatus such as a GPU or CPU. The apparatus obtains visibility information for a set of primitives in a frame associated with the graphics processing. The frame consists of multiple bins, with each bin containing at least one primitive from the set. The apparatus then configures a density map based on the visibility information, where the density map includes density data representing the amount of primitives in each bin. The density data for each bin is mapped to a shading rate for that bin.

  • The invention relates to graphics processing methods and devices.
  • The apparatus obtains visibility information for a set of primitives in a frame.
  • The frame is divided into multiple bins, each containing at least one primitive.
  • A density map is created based on the visibility information.
  • The density map includes density data representing the amount of primitives in each bin.
  • The density data for each bin is mapped to a shading rate for that bin.

Potential applications of this technology:

  • Real-time rendering in video games and virtual reality applications.
  • Computer-aided design and modeling.
  • Animation and special effects in movies and television.
  • Scientific visualization and data analysis.
  • Augmented reality and mixed reality experiences.

Problems solved by this technology:

  • Efficiently processing and rendering complex graphics scenes.
  • Optimizing performance and resource usage in graphics processing.
  • Improving visual quality and realism in graphics rendering.
  • Managing and organizing large amounts of graphics data.
  • Enabling real-time interactivity and responsiveness in graphics applications.

Benefits of this technology:

  • Faster and more efficient graphics processing.
  • Improved visual quality and realism in rendered graphics.
  • Enhanced performance and responsiveness in graphics applications.
  • Better utilization of hardware resources.
  • Enables more immersive and interactive graphics experiences.


Original Abstract Submitted

Aspects presented herein relate to methods and devices for graphics processing including an apparatus, e.g., a GPU or a CPU. The apparatus may obtain visibility information for a set of primitives in at least one frame associated with the graphics processing, where the at least one frame includes a plurality of bins, such that at least one bin of the plurality of bins includes at least one primitive of the set of primitives. The apparatus may also configure a density map based on the visibility information for the set of primitives, where the density map includes density data associated with an amount of the set of primitives in each of the plurality of bins. Further, the apparatus may map the density data for each of the plurality of bins to a shading rate for each of the plurality of bins.
