The OrbitCameraController class allows controlling the scene camera along orbital path.
The controls are:
|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.|

|Both left and right mouse button||While both the left and the right mouse button are pressed, mouse movement along y-axis zooms the camera in and out without changing the view center.|
|Arrow keys||Move the camera vertically and horizontally relative to camera viewport.|
|Page up and page down keys||Move the camera forwards and backwards.|
|Shift key||Changes the behavior of the up and down arrow keys to zoom the camera in and out without changing the view center. The other movement keys are disabled.|
|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.|
