On demand geometry and acceleration structure creation

摘要: Systems and methods of geometry processing, for rasterization ray tracing processes provide pre-processing source geometry, such as by tessellating or other procedural modification to produce final on which a rendering will be based. An acceleration structure (or portion thereof) use during is defined based the geometry. Only coarse-grained elements may produced retained, fine-grained within particular element in response collection rays being ready traversal element. Final can recreated demand from engine, intersection units that require testing with primitives. Geometry at different resolutions generated respond demands components.
