Abstract

The systems, apparatuses and methods may provide a way to adaptively process and aggressively cull geometry data. Systems, apparatuses and methods may provide for processing, by a positional only shading pipeline (POSH), geometry data including surface triangles for a digital representation of a scene. More particularly, systems, apparatuses and methods may provide a way to identify surface triangles in one or more exclusion zones and non-exclusion zones, and cull surface triangles in one or more exclusion zones.
