Dense geometry format

A method for encoding mesh data comprising a plurality of geometrical primitives, the method comprising:

• generating, by processing circuitry, control values, wherein each control value is indicative of a position of a geometrical primitive relative to one or more previously stored geometrical primitives;
• generating, by the processing circuitry, an index buffer comprising a plurality of index bits, wherein each index bit indicates either a first reference or a non-first reference to a given vertex of the geometrical primitive;
• and
• storing, by the processing circuitry, the encoded mesh data corresponding to the control values and the index buffer in a data block.

A ray tracing system comprising:

• a memory configured to store mesh data comprising a plurality of geometrical primitives;
• and
• encoding circuitry configured to:
• retrieve the mesh data from the memory;
• generate control values, wherein each control value is indicative of a position of a geometrical primitive relative to one or more previously stored geometrical primitives;
• generate a compressed index buffer comprising a plurality of index bits, each index bit indicative of either a first reference or a non-first reference to a given vertex of the geometrical primitive;
• and
• store the control values and the compressed index buffer in a data block.
