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 provides allows a user to place a point on a model surface that is used as a focus point for tool operations. The focus point is a geometry sphere that shows orientation and relative position of the view in the scene.

15. A method of placing a 3D geometry sphere in a three dimensional model space as a focus point for actions in the space, comprising:
-
detecting activation of a mouse button; determining whether a cursor controlled by the mouse is over a model in the space; determining an intersection of the cursor with the model and displaying the sphere on a surface of the model at the intersection point when the cursor controlled by the mouse is over the model in the space; determining whether an active tool allows off an model focus point and displaying the sphere a predetermined distance from a view of a scene when the cursor is not over the model; keeping the point at a previous position when the cursor is not over the model and a tool does not allow the point to be displays off the model surface; and making the sphere invisible when the button is deactivated.

17. A computer readable storage for controlling a computer apparatus, comprising:
- a program allowing use of a tool action focus point in a scene including a model and allowing the focus point to be moved when a cursor for controlling the focus point is over the model.
