## Detailed Description

The OrbitCameraController class allows controlling the scene camera along orbital path.

--- | ---
Left mouse button | While the left mouse button is pressed, mouse movement along x-axis moves the camera left and right and movement along y-axis moves it up and down.

Alt key | Changes the behovior of the arrow keys to pan and tilt the camera around the view center. Disables the page up and page down keys.
