Adding color to the previous example, we obtain tinted Perlin Clouds; allowing the color values to overflow past 1 gives us Perlin Plasma. A shift in coordinates reveals that the Frocessing implementation of Perlin noise is symmetric about all three axes (not necessarily implying that it’s incorrect if you stay in one octant…), producing Perlin . . . → Read More: Perlin Color

Here are two instances of the same demo, modeled after the one Seb Lee-Delisle showed last fall, built with two different Flash implementations of 3D Perlin noise. The one on the right uses Ron Valstar’s Perlin class (as does Seb’s demo), which appears to be a faithful port of Ken Perlin’s Improved Noise reference implementation . . . → Read More: Perlin Clouds and Frocessing (with an F)
