![]() ![]() Note that I haven’t done much research into efficient implementations of Perlin noise, so it’s quite possible I’ve rediscovered someone else’s technique. But while reading it it occured to me that it might be possible to do Perlin noise using a single texture lookup, rather than the 8 samples it normally uses (for 3D noise), or the 4 samples for simplex. I started by reading this splendid paper on “Simplex Noise”, Perlin’s faster version of his classic noise. ![]() The first step, of course, is implementing Perlin noise. So, I figured I’d leverage those abilities into my hobby programming projects. Those years of using POV have given me a lot of skills with procedurally generated textures & shapes that I seldom get a chance to use in my day job. I’m a POV-Ray fanatic, using it for everything from art to drawing graphs.
