a graphics pipeline apparatus comprising;
a positional only shading pipeline to;
position geometry data, the geometry data including surface triangles for a digital representation of a scene;
perform a screen space transformation; and
cull at least one of the surface triangles; and
a render pipe to render the surface triangles remaining following the culling.

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 surface triangles in one or more exclusion zones.
