1. A computer-implemented method of processing rays in a ray bundle in a graphics processing system, the method comprising:
executing a plurality of instances of a shader program, an instance corresponding to a ray of the ray bundle;
wherein the shader program is operable to utilize data determined by the execution of an instance of the shader program corresponding to a first ray of the ray bundle in the execution of an instance of the shader program for a further ray of the ray bundle.
