4D Noise

4D Noise component by giulio@mcneel.com creates Perlin and Simplex noise. In the Grasshopper scripting on RhinoCommon at McNeel Europe, they teach to program a component that does this, in C# and Vb.Net. Grasshopper contains a 1D Perlin noise function (similar to sines summations), but this functionality cannot be directly extended to more dimensions.

This add-on forms smooth 4D Perlin noise and Simlex noise, two very well-known smooth noise functions investigated by Ken Perlin. Inputs are:   – a point pt: the location to sample – a number (double) t: the “location” in time – a scale (number): a multiplier to change the scale of the values passed by pt and t.
