Method for navigating in a multi-scale three-dimensional scene
First Claim
1. A method for navigating a three-dimensional scene in a viewing area, comprising:
- associating a point of interest with a reference shape, the reference shape being related to a three-dimensional object; and
displaying a scene according to a user-requested action while keeping the point of interest within the reference shape and within the viewing area.

Abstract
A method for navigating a 3D scene in a viewing area includes associating a point of interest with a reference shape, which is related to the shape of the 3D object, and displaying a scene according to a user-requested action, while keeping the point of interest within the reference shape and within the viewing area. The user-requested action may include translation, rotation, and zooming. The point of interest may include scene information such as a magnification factor, local orientation, and global orientation. The methods for performing a user-requested action in a 2D representation of a 3D object include determining a distance between a point of interest and a viewpoint; determining an amount of movement from a user input; and performing the user-requested action at a rate based on the amount of movement from the user input multiplied by a distance factor based on the distance between the point of interest and the viewpoint. A system for displaying a 3D object includes a 2D display for displaying the 3D object and a computer operatively coupled to the 2D display, the computer having a program to display the 3D object on the 2D display, the program adapted to enable translation, zoom, and rotation of the representation while restricting a point of interest within a reference shape and within a viewing window on the 2D display.

21. A method for performing a user-requested action in a two-dimensional representation of a three dimensional object, comprising:
-
associating a point of interest with a reference shape, the reference shape being related to a three-dimensional object;
determining a distance between the point of interest and a viewpoint;
determining an amount of movement from a user input; and
performing the user-requested action, while keeping the point of interest within the reference shape and within a viewing area, at a rate based on the amount of movement from the user input multiplied by a distance factor based on the distance between the point of interest and the viewpoint. - View Dependent Claims (22, 23)
