Abstract: A system for storing geometry data for use by a graphics processor when rendering a frame that represents a view of a scene using a ray tracing process. The system comprises a processing circuit that is configured to prepare a ray tracing acceleration data structure for use when rendering a frame that represents a view of a scene using a ray tracing process. Graphics primitives for an end point of the ray tracing acceleration data structure is sorted into groups of contiguous graphics primitives, and fewer instances of vertex data is stored for a graphics primitive that is shared by at least two graphics primitives of the group of contiguous graphics primitives than the number of graphics primitives in the group of contiguous graphics primitives that share the vertex.
