The present disclosure relates to tile-based rendering systems. In particular comprises a method for encoding primitive metadata into a primitive list in which a primitive metadata command is included into the primitive list that is able to indicate types of primitive metadata from a set of different types of primitive metadata that can be indicated by the primitive metadata command are included into the primitive list in association with the primitive metadata command. The indicated primitive metadata can then be included in the primitive list following the primitive metadata command. Corresponding primitive list formats and graphics processing systems using such primitive metadata command are also disclosed.

Graphics processing methods and systems for encoding primitive metadata

The present disclosure relates to tile-based rendering systems. In particular there is provided a new primitive list format in which a sequence of commands generated for the primitive list includes a number of different respective types of commands including 'primitive' type commands storing primitive data, ‘state’ type commands storing state data and ‘configuration’ type commands for storing configuration data, wherein the primitive, state and configuration data can accordingly be stored separately in the primitive list, using the different respective types of commands. Also disclosed are techniques for encoding the data into the respective different types of commands.

Graphics processing

A method of operating a graphics processor that executes a graphics processing pipeline that can generate a render output using different shading rates is disclosed. First and second input shading rates are combined prior to rasterisation, and a combined shading rate may be propagated through the pipeline instead of the first and second input shading rates. The combined shading rate may then be combined with a third input shading rate at or after the rasterisation stage. This can reduce bandwidth, hardware and energy requirements.
