Procedural Content Generation

Unity 6000.2.9f1 project that turns Perlin, Simplex, and Value noise into terrain meshes with adjustable height curves, vertex colouring, and water planes.

Repository Structure

• PCG/Assets/Scripts/PerlinNoise.cs, SimplexNoise.cs, and ValueNoise.cs hold the seeded generators, all inheriting from NoiseGeneratorBase for fractal (octave) sampling.
• ProceduralTerrain builds the mesh at runtime, applies biome colours, and exposes inspector fields for octaves, persistence, height multipliers, and a Noise Type toggle between the three generators.
• Tweaking the single AnimationCurve heightCurve remaps the sampled noise. Flattening the curve produces gentle plains while steepening it exaggerates cliffs (see the Perlin variants below).

Getting started

1. Open the PCG folder in Unity 6000.2.9f1.
2. Load Assets/Scenes/SampleScene.unity or add the ProceduralTerrain component to an empty GameObject in any scene.
3. (Optional) Adjust the ProceduralTerrain inspector away from its default values. Pick Noise Type, seed, frequency, and curve shape, then enter Play mode to regenerate the mesh.
