Exploring Advanced Geometries

In Chapter 5, Learning to Work with Geometries, we showed you all the basic geometries provided by Three.js. Besides these basic geometries, Three.js also offers a set of more advanced and specialized objects.

In this chapter, we’ll show you these advanced geometries:

• How to use advanced geometries such as THREE.ConvexGeometry, THREE.LatheGeometry, THREE.BoxLineGeometry, THREE.RoundeBoxGeometry, THREE.TeapotGeometry, and THREE.TubeGeometry.
• How to create 3D shapes from 2D shapes using THREE.ExtrudeGeometry. We’ll create a 3D shape from a 2D SVG image, and we will extrude from 2D Three.js shapes to create novel 3D shapes.
• If you want to create custom shapes yourself, you can continue playing with the ones we’ve discussed in the previous chapters. Three.js, however, also offers a THREE.ParametricGeometry object. With parametric geometry, you can create geometry with parameters you can change to effect the shape of...
