Chapter 592: SceneOptimizer

Core Idea

This class can be used to optimized scenes by converting individual meshes into BatchedMesh. This component is an experimental attempt to implement auto-batching in three.js.

Code Examples

import { SceneOptimizer } from 'three/addons/utils/SceneOptimizer.js';

What it demonstrates: Typical usage of SceneOptimizer.

Methods

Method	Description
`.disposeMeshes( meshesToRemove : Set.<Mesh> )`	Removes the given array of meshes from the scene.
`.removeEmptyNodes( object : Object3D )`	Removes empty nodes from all descendants of the given 3D object.
`.toBatchedMesh() : Scene`	Performs the auto-baching by identifying groups of meshes in the scene that can be represented as a single BatchedMesh. The method modifies the scene by adding instances of `Batch…
