36e5c31af7Sopenharmony_ciDescription:
37e5c31af7Sopenharmony_ci
38e5c31af7Sopenharmony_ciThis test set compares images rendered by a reference software
39e5c31af7Sopenharmony_cirasterizer to images rendered by the target. Rasterized points, lines
40e5c31af7Sopenharmony_ciand triangles are compared to reference, and a deviation of 1 pixel in
41e5c31af7Sopenharmony_ciposition is allowed.
42e5c31af7Sopenharmony_ci
43e5c31af7Sopenharmony_ciFill rules are tested using additive blend so that pixels on shared
44e5c31af7Sopenharmony_citriangle edges are filled exactly once. Because exact fill rules are
45e5c31af7Sopenharmony_cinot specified, reference rasterizer uses all valid combinations of
46e5c31af7Sopenharmony_ciLEFT, RIGHT, TOP and BOTTOM.
47e5c31af7Sopenharmony_ci
48e5c31af7Sopenharmony_ciValue interpolation is tested for lines and triangles with
49e5c31af7Sopenharmony_civertex-specific colors, small deviation in interpolated color is allowed.
50e5c31af7Sopenharmony_ci
51e5c31af7Sopenharmony_ciMultisample rasterization is tested with points, lines and triangles.
52e5c31af7Sopenharmony_ciBecause sampling pattern is unknown, deviation in produced colors is
53e5c31af7Sopenharmony_ciallowed.
