AUTOMATIC SELECTION OF CENTER OF ROTATION FOR GRAPHICAL SCENES

摘要

A center of rotation may automatically be selected for graphically displayed data. The rotation center may be automatically selected based on what is determined to be of interest to the user, the current display of the data, and other parameters. For example, if a user has selected a portion of data, the center of rotation may be within the center of the selected data. If a user has positioned a cursor within a portion of displayed data, the center of rotation may be the center of the data portion including the cursor. If the data as a whole is approximately centered about the graphical coordinate origin, or within a threshold of the origin, the data may be rotated about the origin. If the data as a whole is approximately centered at least a certain distance away from the graphical coordinate origin, the data may be rotated about the center of the data as a whole.

主权项

1. A method for displaying data, comprising:
providing an image of multi-dimensional data within a graphical portion of an interface; automatically determining a center of rotation for the multi-dimensional data, wherein the center of rotation is determined based on data selected by a user; receiving input to rotate the data about the center of rotation; and displaying the data rotated about the automatically determined center of rotation.
