Three.js - Geometries

Geometries are used to create and define shapes in Three.js. Three.js has many types of built-in geometries, both 2D and 3D.

In this chapter, we ll discuss basic built-in geometries. We’ll first look at the 2D geometries, and after that, we’ll explore all the basic 3D geometries that are available.

Sr.No	Geometrys & Description
1	Plane Geometry The THREE.PlaneGeometry creates a simple 2D rectangle.
2	Circle Geometry The THREE.CircleGeometry creates a simple 2D circle.
3	Ring Geometry The THREE.RingGeometry creates a D disc with a hole in the center.
4	Box Geometry The THREE.BoxGeometry creates a simple 3D box with specified dimensions.
5	Sphere Geometry The THREE.SphereGeometry creates 3D sphere geometries.
6	Cypnder Geometry To create a cypnder in Three.js, you can use the Three.CypnderGeometry.
7	Cone Geometry You can use THREE.ConeGeometry to create a cone. It is very similar to CypnderGeometry, except it only allows you to set the radius instead of radiusTop and radiusBottom.
8	Torus Geometry Torus is a tube-pke shape that looks pke a donut. You can use THREE.TorusGeometry to create a torus in Three.js.
9	TorusKnot Geometry A torus knot is a special kind of knot that looks pke a tube that winds around itself a couple of times.
10	Polyhedron Geometry A polyhedron is a geometry that has only flat faces and straight edges.
