Navigation system for a 3D virtual scene (VI)

Abstract

A navigation system for navigating a three-dimensional (3D) scene that includes a model or object with which a user can interact. The system accommodates and helps both novice and advanced users. To do this, the system allows a user to designate a point on a model and the system moves the view toward that point. A perspective scale is provided that shows the user the relative position of the current view from the starting point of the view to the surface point.
