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