Exercise – creating a rotated tesseract cube

In this exercise, we will teach you how to create the shape shown (a tesseract cube) in Figure 6.12.

Figure 6.12: Rotated tesseract cube

Figure 6.12: Rotated tesseract cube

Sketching the basic idea

This shape can be made by duplicating a cube while making the duplicate cubes smaller and smaller and rotating each cube by the amount of their unique ID.

We will start by adding a cube. We’ll duplicate this cube, and we’ll scale it in a way that they don’t intersect with the other duplicates. Then, we will rotate the cube in a way that is satisfying to the end user.

To top this exercise off, we will add a wireframe effect to this shape, as seen in Figure 6.12.

Introducing the nodes you’ll need

In Figure 6.13, you’ll see what nodes we will use in this exercise.
