Chapter 6. Advanced Geometries and Binary Operations
In the previous chapter, 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 and cover the following subjects:
- How to use advanced geometries such as
THREE.ConvexGeometry,THREE.LatheGeometry, andTHREE.TubeGeometry. - How to create 3D shapes from 2D shapes using
THREE.ExtrudeGeometry. We'll do this based on a 2D shape drawn using functionality provided by Three.js, and we'll show an example where we create a 3D shape based on an externally loaded SVG image. - If you want to create custom shapes yourself, you can easily amend the ones we've discussed in the previous chapters. Three.js, however, also offers a
THREE.ParamtericGeometryobject. With this object, you can create a geometry based on a set of equations. - Finally, we'll look at how you...
