I’ve been attempting to convert an HLSL Pixel Shader from the VVVV website, into a GLSL Fragment Shader, with what could be termed ‘mixed success’.
I’ve managed to convert all the variables, and was hoping that the underlying algorithms, which I left exactly as they were, would produce a usable result. I haven’t managed to get anything like the screenshot on the website. I don’t understand the mathematics, so I have no idea where to start debugging it.
A useful exercise, maybe, but not entirely a successful one.
