在将网格添加到three.js中的场景之前，如何设置网格的位置 [英] How can I set the position of a mesh before I add it to the scene in three.js

问题描述

在three.js中，我想在场景中的位置添加网格物体

In three.js, I want to add a mesh to a position in the scene

我尝试过：

// mesh is a THREE.Mesh
scene is a THREE.Scene
scene.add(mesh)
scene.updateMatrixWorld(true)
mesh.matrixWorld.setPosition(new THREE.Vector3(100, 100, 100))
scene.updateMatrix()

但它不会影响任何事情。

BUT it didn't affect anything.

我该怎么办？

推荐答案

我建议你查看这里的文件：
http://threejs.org/docs/#Reference/Objects/Mesh
正如您在文档页面顶部所见，Mesh继承自 Object3D 。这意味着您可以使用Object3D提供的所有方法或属性。因此，单击docu-page上的 Object3D 链接并检查属性列表。你会发现属性 .position 。单击 .position 以查看它是什么数据类型。 Paha..its Vector3 。

i would recommend you to check the documenation over here: http://threejs.org/docs/#Reference/Objects/Mesh As you can see on the top of the docu-page, Mesh inherits from "Object3D". That means that you can use all methods or properties that are provided by Object3D. So click on the "Object3D" link on the docu-page and check the properties list. You will find propertie ".position". Click on ".position" to see what data-type it is. Paha..its Vector3.

因此，请尝试执行以下操作：

So try to do the following:

//scene is a THREE.Scene
scene.add(mesh);
mesh.position.set(100, 100, 100);
