create a scene with three platonic solids: a tetrahedron, a cube, and an octahedron.

The code I have are two cubes that rotate and have different materials. I am still in need of a camera that you can control in any way you want, either keyboard or mouse or both. You should be able to navigate the scene and look at all the objects from different points of view. two viewports (left and right.) One of the viewports should be fixed and the other should use the camera you control.
