Procedural Content Generation for Unity Game Development

Chapter 9. Generating a 3D Planet

So far we've tackled 2D content generation and some complex sound generation. You made a 2D Roguelike game that can continually generate game content for as long as the player can survive. However, with our 2D game complete, it's time to add another dimension to our PCG learning and move into 3D.

In this chapter, we will be procedurally generating a 3D planet. You can see an example of a procedurally generated shape in the following figure. Then, just for fun, we'll add the scripts necessary to take a first person view walk on that planet. However, 3D does pose some new considerations when applying PCG. Here's what you can expect to learn in this chapter:

• 2D versus 3D rendering
• Space and time complexity of 3D object ...
