In this course, you will learn how to take a simple WebGL cube and gradually turn it into a Rubik’s Cube structure. This is a project-based WebGL course designed for learners who already understand the basics of drawing a cube and now want to build something more interesting, visual, and practical. We begin by reviewing how a basic 3D cube is created using vertices, colors, buffers, shaders, and draw calls. From there, we improve the cube by adding rotation so that we can clearly see its 3D shape.
After that, we start transforming the cube into a small cubie. You will learn how scaling makes the cube smaller, how translation moves it into position, and how loops allow us to reuse the same cube multiple times.
Step by step, we build the Rubik’s Cube structure:
- First, we break the front layer into a 3×3 grid of cubies.
- Then, we explain how x and y positions control the rows and columns.
- Next, we add the z direction to create front, middle, and back layers.
- Finally, we rotate the full 3×3×3 structure so students can clearly see the complete 3D object.
