Abstract

Marking “Clipped Triangles” as visible triangles for all tiles may be avoided by instead finding an approximate clipping area and marking the triangles as visible only in those tiles in the Position Only Shading Pipe (POSH) pipe. This avoids rendering the triangle in the replay pipe in those tiles where it may not be visible.
