Chapter 21: BoxGeometry

Core Idea

A geometry class for a rectangular cuboid with a given width, height, and depth. On creation, the cuboid is centred on the origin, with each edge parallel to one of the axes.

Key Concepts

Code Examples

const geometry = new THREE.BoxGeometry( 1, 1, 1 );
const material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
const cube = new THREE.Mesh( geometry, material );
scene.add( cube );

• What it demonstrates: Typical usage of BoxGeometry.

Constructor

Signature
new BoxGeometry( width : number, height : number, depth : number, widthSegments : number, heightSegments : number, depthSegments : 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. BoxGeometry extends: EventDispatcher → BufferGeometry
2. Most relevant properties: parameters.
