19    Rasterization Tests
20
21Tests:
22 + dEQP-GLES2.functional.rasterization.*
23
24Includes:
25 + Primitive rasterization
26   - Points
27   - Lines
28   - Triangles
29 + Individual triangles, triangle strips and triangle fans
30 + Varying interpolation in all primitives
31 + Projected (w != 1) and non-projected (w == 1) coordinates
32 + Fill rule verification
33 + Culling
34 + Multisample rasterization
35
36Description:
37
38This test set compares images rendered by a reference software
39rasterizer to images rendered by the target. Rasterized points, lines
40and triangles are compared to reference, and a deviation of 1 pixel in
41position is allowed.
42
43Fill rules are tested using additive blend so that pixels on shared
44triangle edges are filled exactly once. Because exact fill rules are
45not specified, reference rasterizer uses all valid combinations of
46LEFT, RIGHT, TOP and BOTTOM.
47
48Value interpolation is tested for lines and triangles with
49vertex-specific colors, small deviation in interpolated color is allowed.
50
51Multisample rasterization is tested with points, lines and triangles.
52Because sampling pattern is unknown, deviation in produced colors is
53allowed.
