A bounce light map for a scene is determined for use in rendering the scene in a graphics processing system. Initial lighting indications representing lighting within the scene are determined. For a texel position of the bounce light map, the initial lighting indications are sampled using an importance sampling technique to identify positions within the scene. Sampling rays are traced between a position in the scene corresponding to the texel position of the bounce light map and the respective identified positions with the scene. A lighting value is determined for the texel position of the bounce light map using results of the tracing of the sampling rays. By using the importance sampling method described herein, the rays which are traced are more likely to be directed towards more important regions of the scene which contribute more to the lighting of a texel.
A computer-implemented method of determining a bounce light map for a scene for use in rendering the scene in a graphics processing system, the method comprising:
A graphics processing unit configured to determine a bounce light map for use in rendering a scene, the graphics processing unit comprising:
A non-transitory computer readable storage medium having stored thereon a computer readable dataset description of an integrated circuit that, when processed in an integrated circuit manufacturing system, causes the integrated circuit manufacturing system to manufacture a graphics processing unit configured to determine a bounce light map for use in rendering a scene, the graphics processing unit comprising:
