Custom OrbitControls are very unusable (bad UX).

The custom OrbitControls uses middle-mouse button (which most touchpad laptops do not have) for panning behavior, and it is not configurable.

I recommend using the OrbitControls from Three.js, and not trying to emulate rviz. Rviz camera controls have very bad UX. Or at least these things should be configurable.
