Intermediate Topic 32 of 49 Graphics, Vision & Media
Noise Functions
Perlin-style randomness for natural patterns.
How it works
Perlin and simplex noise give smooth pseudo-random gradients; summing octaves (fBm) creates natural detail for terrain, clouds and textures.
Where it is used
Procedural textures.
Common pitfall
Directional artifacts in naive implementations.
Where it fits in the course
Noise Functions is topic 32 of 49 in Graphics, Vision & Media, rated Intermediate. It follows Procedural Generation. The next topic is Image Filtering.
