Abstract

New mesh shader graphics pipelines allow fine grained processing of input geometry which is split into small chunks of geometery---so called "meshlets". To match geometry processing efficiency of classical shader stages (from vertex to geometry shaders), an optimized mesh shader implementation is required using the two new tightly-coupled shader stages: task shaders, and mesh shaders. Fine-grained view frustum and backface culling on a per-meshlet basis further improve performance.
