In this chapter, we covered many different parts of Three.js to create the maze with a walking cube. We started by adapting a standard JavaScript library since Three.js didn't provide us with a geometry we could use out of the box. As you've seen, it is pretty easy to adapt these kinds of libraries and use them as input for creating Three.js geometries.

In this chapter, we've also spent a lot of time on rotation. By default, Three.js rotates objects around their center point. For many use cases, this is enough, but for more advanced animations or rotations, you need to approach this differently by moving its rotation point (also called pivot point). If you want to change its rotation point, you first need to translate a geometry and change this pivot point before applying the rotation.

Another aspect of rotation that you need to understand is the difference between the rotation property of a mesh, and applying rotations through a matrix transformation. When you set the rotation property...
