three.js - mesh group example? (THREE.Object3D() advanced)

Question

I\'m attempting to understand how to group / link child meshes to a parent. I want to be able to:

• drag the parent
• rotate child elements relative to t

Answer 1

another way, because a mesh can be a parent too

meshParent.add(meshChild1);
meshParent.add(meshChild2);
scene.add(meshParent);

or

mesh1.add(mesh2);
mesh3.add(mesh1);
scene.add(mesh3);

mesh3 manipulates all meshes, mesh1 manipulates itself and mesh2, mesh2 manipulates itself
