Chapter 54: TorusGeometry

Core Idea

A geometry class for representing an torus.

Key Concepts

Code Examples

const geometry = new THREE.TorusGeometry( 10, 3, 16, 100 );
const material = new THREE.MeshBasicMaterial( { color: 0xffff00 } );
const torus = new THREE.Mesh( geometry, material );
scene.add( torus );

• What it demonstrates: Typical usage of TorusGeometry.

Reference Tables

Constructor

Signature
new TorusGeometry( radius : number, tube : number, radialSegments : number, tubularSegments : number, arc : number, thetaStart : number, thetaLength : number )

Properties

Property	Description
.parameters : Object	Holds the constructor parameters that have been used to generate the geometry. Any modification after instantiation does not change the geometry.

Key Takeaways

1. TorusGeometry extends: EventDispatcher → BufferGeometry
2. Most relevant properties: parameters.
