The noise value can be animated by moving through the noise space, as demonstrated in the first example above. What others are saying In this Coding Challenge, I create a procedural terrain using Perlin Noise and the beginShape() function in Processing. the tutorial on Perlin Noise. Perlin Noise was created by Ken Perlin (who won the Academy Award for his achievement) in 1983. They are mostly based on a 3d simplex (perlin) noise function such as texture distortion and tint, in addition to some trippy effects like lerping the hue, saturation, or value. , values increase and decrease in a seemingly natural way. A 3D noise field is set, agents move in a spherical space according to the underlaying field allowing to visualise the characteristics of the 3d noise.
