Left one has texture 35e5c31af7Sopenharmony_cicoordinates choosed to trigger minification while right one tests 36e5c31af7Sopenharmony_cimagnification. Reference value for depth comparison is uniform. 37e5c31af7Sopenharmony_ci 38e5c31af7Sopenharmony_ciThe rendered image is compared against a reference that is produced by 39e5c31af7Sopenharmony_cireference renderer. A simple threshold-based comparison is used. 40e5c31af7Sopenharmony_ci 41e5c31af7Sopenharmony_ciIn tests where filtering mode is not NEAREST or NEAREST_MIPMAP_NEAREST 42e5c31af7Sopenharmony_ciall r values are accepted if reference image contains r that is not 43e5c31af7Sopenharmony_ciexactly 0 or 1. Reference is computed using executing comparisons 44e5c31af7Sopenharmony_cifor all texels and combining results in same fashion as in regular 45e5c31af7Sopenharmony_citexture lookups. 46
