WGF11 Clipping

  • Article

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

This topic applies to the following test jobs:

  • WGF11 Clipping

  • WGF11 Clipping (WoW64)
