如何在threejs中克隆collada模型？

问题描述

我已经加载了 .dae 模型，我想在我的场景中使用更多次。此代码适用于网格，但 collada.scene 对象不是网格：

I've loaded a .dae model, which I would like to use more times in my scene. This code works with meshes, but the collada.scene object isn't a mesh:

var mesh2 = new THREE.Mesh( loadedMesh.geometry, loadedMesh.material );

如何在一些对象之间共享相同的collada模型？

How is it possible, to share the same collada model between some objects?

推荐答案

dae场景不是网格，但肯定有网格。
您应该在console.log中使用collada对象，或在 load 函数中放置断点，并检查所需的网格在哪里。

The dae scene is not a mesh, but there's certainly a mesh in it. You should console.log the collada object, or put a breakpoint in the load function, and inspect where is the mesh you want.

给定位于的网格collada.scene.children [0]

在 load 函数中，将网格存储在某处，比如 window.referenceModel

In the load function, store the mesh somewhere, say window.referenceModel

window.referenceModel = collada.scene.children[0];

稍后，当您想要克隆此模型时

Later, when you want to clone this model

var refObject = window.referenceModel;
var clone = new THREE.Mesh( refObject.geometry, refObject.material );
// here you can apply transformations, for this clone only
scene.add( clone );
