Hovercam is kind of confusing, because it is so different from Camera3D. It has built-in shortcuts to handle a particular type of motion. That is: Point at the center of a spherical area. Translate across the surface of that sphere using intuitive "up down" "left right" controls. The radius of that spherical area is determined by the distance determined by "distance" and the pseudo x and y postions are handled through tiltAngle and Panangle. These shortcut computations are handled for you whenever you call "hover()". I think of all the cameras, hovercamera is the hardest to understand when you come to away3D because it does not behave like any real-world conterpart, and because it uses a simplified interface to solve the complexities of plottiong points and rotations along the surface of a sphere.
Is that description at all helpful?
