WebDithering works by taking a grayscale value (from 0 to 1) and matching the value to the corresponding dot pattern. For Ordered Dither it works like: If the value is 1, then the pattern has a lot of white dots. If the value is 0.5, … WebMay 17, 2024 · Here is some GLSL to do that. 1 2 vec3 lightTangent = normalize (cross (c_lightDir, vec3 (0.0f, 1.0f, 0.0f))); vec3 lightBitangent = normalize (cross (lightTangent, c_lightDir)); This code assumes that the light direction is not ever going to point straight up.
