How can we use mathematical noises to generate heightmaps procedurally and apply them on Unity 3d terrains? Let's discover more in this video/text tutorial: "How to use mathematical noises for procedural heightmap generation in 30 minutes" :)
You can read it in text format on Medium, or watch it on Youtube.
In this 30 minutes-tutorial, I'm discussing the Perlin noise, Unity 2d textures, terrain objects and the Immediate Mode GUI (IMGUI) to create a basic small-sized noise-based heightmap exploration engine!
This Github repo contains additional resources to go further:
- various noise algorithms
- an improved manager to tweak even more parameters
- a basic GLSL shader to show the level curves on the terrain
