Chapter 156: BufferGeometryLoader

Core Idea

Class for loading geometries. The files are internally loaded via FileLoader.

Code Examples

const loader = new THREE.BufferGeometryLoader();
const geometry = await loader.loadAsync( 'models/json/pressure.json' );
const material = new THREE.MeshBasicMaterial( { color: 0xF5F5F5 } );
const object = new THREE.Mesh( geometry, material );
scene.add( object );

• What it demonstrates: Typical usage of BufferGeometryLoader.
