Determination of data availability in memory and identification of data not needed for rendering

A determination is made as to whether data needed for processing is already available in memory, and if not, the required data is generated ready for use. Specifically, when a fragment reaches a texturing stage, it is determined whether the texture to be applied is a static or dynamic texture (Step 24). If it is determined that the required texels relate to a dynamic texture, then the system first tries to fetch those texels from a dynamic texture memory (Step 25). If it is found that the texels are not available in the dynamic texture memory, then the relevant texels are generated in an "on-demand" fashion (Step 27) and stored in the dynamic texture memory (Step 28), so that they can be applied to the fragment. Also disclosed is the identification of unnecessary dynamic graphics data not required for rendering a scene prior to the rendering.

Systems and methods of geometry processing, for rasterization and ray tracing processes provide for pre-processing of source geometry, such as by tessellating or other procedural modification of source geometry, to produce final geometry on which a rendering will be based. An acceleration structure (or portion thereof) for use during ray tracing is defined based on the final geometry. Only coarse-grained elements of the acceleration structure may be produced or retained, and a fine-grained structure within a particular coarse-grained element may be Produced in response to a collection of rays being ready for traversal within the coarse grained element.
