Procedural Terrain Generation with Unity

Course Preview

The creation of beautiful virtual terrains isn’t just the domain of the artist but also of the programmer. What if you could use your programming skills in C# to manipulate a mesh to create realistic landscapes using algorithms developed by researchers studying landscape formation and erosion?

Learn how to program and work with: Voronoi Tessellation, Midpoint Displacement, Perlin Noise, Splat Maps, Trees and Vegetation, Clouds, Weather, Erosion, and water.
