WebMay 3, 2024 · 3 Answers Sorted by: 44 What causes branching in GLSL depends on the GPU model and OpenGL driver version. Most GPUs seem to have a form of "select one of two values" operation that has no branching cost: n = (a==b) ? x : y; and sometimes even things like: if (a==b) { n = x; m = y; } else { n = y; m = x; }
WebOne expression might be better than the other. For example: result = 0.5 * (1.0 + variable); result = 0.5 + 0.5 * variable; The first one may be converted into an add followed by a multiply.
