An example image made with the 3D Perlin noise.


 

A 2D animation with 3D noise.

It's a creative coding animation made with the 'Processing' programming language.

I drew 2D animation with 3D noise as noise(x, y, time). And I think if I increased time value monotonously, the animation would be something boring. So I used another 2D noise to increase the time value. It worked! 👍
