PlanetGeneration

Procedural generation of planets (or asteroids, etc.) using Unity.

Techniques used:

• 3D fBm using 3D Perlin noise
• Procedural sphere generation from cube normalization for trivial UV mapping
• Vertex displacement using the 3D fBm
• Numerical computation of vertex position's derivates to compute vertex normals
• Multithreaded mesh generation with dynamic LOD using quadtrees
• GPU-based planet texturing using Unity's surface shaders
