Intermediate Topic 31 of 49 Graphics, Vision & Media

Procedural Generation

Algorithmically creating content like terrain.

How it works

Procedural generation creates content algorithmically instead of by hand, using rules, randomness and parameters. Techniques include noise functions for terrain and textures, L-systems for plants, Wave Function Collapse and grammars for levels and buildings, cellular automata for caves, Voronoi diagrams, random walks, and generative models. A seed makes output reproducible, so large worlds can be generated on demand from few bytes of data.

Where it is used

Games such as Minecraft, No Man's Sky and roguelikes, film visual effects, architecture, texture authoring tools and data augmentation for machine learning use procedural generation.

Common pitfall

Pure randomness gives bland or broken results, so constraints, validation and designer control are needed. Seams between generated chunks and unreachable areas must be handled. Reproducibility requires deterministic random number generators across platforms. Output can feel repetitive without variety. Combine procedural methods with hand-authored elements, expose parameters and test many seeds.

Where it fits in the course
