Detailed Description

Tests 2D projective texturing (STAGE_2D_PROJECTIVE / PS_TEXTUREMODES_PROJECTIVE2D) with explicit Q coordinate interpolation across quads and triangles.

Constructor & Destructor Documentation

TextureProjective2DTests()

	)

Initializes the test suite and creates test cases.

Remarks

ExplicitQ_MixedCorners_Quad Evaluates projective coordinate division on a quad with mixed corner Q values:

• TL: s=-1, t=0, q=-1 -> s/q = 1.0, t/q = 0.0
• TR: s=1, t=0, q=1 -> s/q = 1.0, t/q = 0.0
• BR: s=1, t=1, q=-0.25 -> s/q = -4.0, t/q = -4.0
• BL: s=-1, t=1, q=0 -> s/q = -inf, t/q = inf Tests hardware division across negative, positive, fractional, and zero Q values.

ExplicitQ_MixedCorners_Bitri Evaluates the mixed corner Q configuration triangulated as two triangles.

ExplicitQ_HorizontalCross_Quad Evaluates projective coordinate division across a horizontal zero-crossing on a quad:

• Left: q = +1.0, Right: q = -1.0.
• Coordinates: TL(0,0,q=1), TR(-1,0,q=-1), BR(-1,-1,q=-1), BL(0,1,q=1). Tests continuous interpolation and sign preservation across the q = 0 singularity.

ExplicitQ_HorizontalCross_Bitri Evaluates the horizontal zero-crossing test triangulated as two triangles.

ExplicitQ_VerticalCross_Quad Evaluates projective coordinate division across a vertical zero-crossing on a quad:

• Top: q = +1.0, Bottom: q = -1.0.
• Coordinates: TL(0,0,q=1), TR(1,0,q=1), BR(-1,-1,q=-1), BL(0,-1,q=-1). Tests vertical interpolation across the q = 0 singularity.

ExplicitQ_VerticalCross_Bitri Evaluates the vertical zero-crossing test triangulated as two triangles.

ExplicitQ_OpposingCorners_Quad Evaluates projective coordinate division on a saddle-shaped Q surface:

• TL(0,0,q=1), TR(-1,0,q=-1), BR(1,1,q=1), BL(0,-1,q=-1). Tests zero-crossings along both diagonals of the quad.

ExplicitQ_OpposingCorners_Bitri Evaluates the saddle-shaped Q surface triangulated as two triangles.

ExplicitQ_PositiveGradient_Quad Evaluates projective division with all-positive Q gradient (q in [0.25, 2.0]):

• TL(0,0,q=0.25), TR(2,0,q=2.0), BR(2,2,q=2.0), BL(0,0.25,q=0.25). Tests non-linear perspective warping purely in the positive Q domain.

ExplicitQ_PositiveGradient_Bitri Evaluates the all-positive Q gradient triangulated as two triangles.

ExplicitQ_NegativeGradient_Quad Evaluates projective division with all-negative Q gradient (q in [-0.25, -2.0]):

• TL(0,0,q=-0.25), TR(-2,0,q=-2.0), BR(-2,-2,q=-2.0), BL(0,-0.25,q=-0.25). Tests projective interpolation purely in the negative Q domain.

ExplicitQ_NegativeGradient_Bitri Evaluates the all-negative Q gradient triangulated as two triangles.

ExplicitQ_ZeroCorner_Quad Evaluates projective division with three corners at q = 1.0 and BL corner at q = 0.0:

• TL(0,0,q=1), TR(1,0,q=1), BR(1,1,q=1), BL(0,1,q=0). Tests interpolation behavior when a single corner is at the singularity.

ExplicitQ_ZeroCorner_Bitri Evaluates the single zero corner configuration triangulated as two triangles.

ExplicitQ_UniformSigns Evaluates constant Q values across 5 quads per wrap mode:

• q = +1.0, q = -1.0, q = +0.5, q = -0.5, q = 0.0. Compares algebraic sign preservation (-s/-q == s/q) and zero divisor handling.
