Modelling by numbers: An introduction to procedural geometry.

Supplementary (Terrain)

A while ago, I posted a tutorial, or rather a series of tutorials, about generating procedural meshes in Unity. It got quite long, and I had to remove a bunch of topics that I had originally intended to cover. The Modelling by numbers tutorial got a very positive response, and also quite a few people asking for extra information, mostly to do with the topics that I had discarded. So I figured I’d revisit them. What follows is one of them.

Part One B: Making planes interesting

OK, we’ve learned to make planes and boxes. Those are basic building blocks. Blocks that can be combined and extended in all kinds of interesting ways. Let’s look at a couple of examples… Continue reading →

Part One A: The plane

Procedural geometry is geometry modelled in code. Instead of building 3D meshes by hand using art software such as Maya, 3DS Max or Blender, the mesh is built using programmed instructions. Continue reading →
