In the previous lesson , we explored the concept of geometries and how they form the backbone of any 3D object in Three.js. Today, we’re zooming in on one of the most fundamental and widely used geometries: BoxGeometry . Whether you’re creating a simple cube, a rectangular prism, or even a complex structure made up of multiple boxes, the BoxGeometry is your go-to tool. By the end of this chapter, you’ll know exactly what a BoxGeometry is, how to create one, and how to customize it to fit your needs. Let’s dive in! 🚀
