One of the first things I like to do when I implement any procedural texture is slap it onto a sphere, and then rotate the sphere. That’s a pretty surefire way to find out whether there are any unwanted patterns, repetitions, or other objectionable visual artifacts.
So I did just that with my latest implementation of 3D noise. Fortunately, it looks as though this particular implementation passes the rotating sphere test.

More tomorrow.
