three.js - 如何在一个对象中组合两个立方体？

Question

我需要将一组对象的位置作为一个项目来管理。

我有：

tankMesh1 = new THREE.Mesh(geometry, material);
tankMesh2 = new THREE.Mesh(geometry, material);
scene.add(tankMesh1);
scene.add(tankMesh2);

tankMesh2.position = tankMesh2.position + offset * cos ( angle )

我需要：

tankMeshBig = new THREE.Mesh(tankMesh1 , tankMesh2 );

Answer 1

您可以使用新的THREE.Object3D()：

js：

var group=new THREE.Object3D();

tankMesh1 = new THREE.Mesh(geometry, material);
group.add(tankMesh1);

geometry = new THREE.CubeGeometry(3, 2, 5);
tankMesh2 = new THREE.Mesh(geometry, material);
tankMesh2.position.y = 3;
group.add(tankMesh2);

group.rotation.y = 3.141/3;

scene.add(group);
