SkeletonUtils - Cloning 3D Model in Three.js
Wonje Jangthreejs • Fri Jul 05 2024 16:20
To clone a model in Three.js we need to use 'SkeletonUtils' module. The 'SkeletonUtils' module in three.js provides utilities for working with skinned meshes and skeletons. These utilities are particularly useful for tasks such as cloning skinned meshes while preserving their skeletons. This can be important when you need to create multiple instances of a character or object with complex animations and deformations.
SkeletonUtils.Clone
The SkeletonUtils.clone function is designed to create a deep copy of a skinned mesh, including its skeleton. This is necessary because a simple .clone on a skinned mesh won't correctly duplicate the skeleton's hierarchical structure and the relationships between the bones.
1. import 'SkeletonUtils'
javascript
1import * as SkeletonUtils from 'three/examples/jsm/utils/SkeletonUtils.js';
2. Load a Model
javascript
1import { GLTFLoader } from 'three/examples/jsm/loaders/GLTFLoader.js';
2
3const loader = new GLTFLoader();
4let originalModel;
5
6loader.load('path/to/your/model.glb', (gltf) => {
7 originalModel = gltf.scene;
8 scene.add(originalModel);
9});
3. Clone Model
javascript
1function cloneModel(model) {
2 const clonedModel = SkeletonUtils.clone(model);
3 scene.add(clonedModel);
4 return clonedModel;
5}
6
7// Example usage
8if (originalModel) {
9 const clonedModel = cloneModel(originalModel);
10 clonedModel.position.set(0, 0, 10); // Move the cloned model to a different position
11}
