WGF11 Clipping (WoW64)

This automated test verifies D3D graphics driver/hardware conformance for geometry clipping features that are not specifically tested elsewhere.

Specifically, this test features the following characteristics:

• Quad rendered to render target

• Each RT pixel tested programmatically against expected value

• Clipdist, Culldist values cycled independently for each vertex, to test shaded clipping

• W values manipulated independently for each vertex, to test fixed clipping

• Tests multisample with fixed sample pattern and potential deviation

• Might need some uncertainty epsilon for floating-point precision issues

• Consider non perspective correct attribute interpolation (though this may be better tested in rasterization tests)

• Be particularly aware of guardband and z-clip

• Guardband may hide some clipping problems

• Z-clipping has no guardband protection
