Dynamic control of panning operation in computer graphics

摘要

A graphical universe that is larger than a display screen is displayed on a screen using a panning operation. To view portions of the graphical universe, a cursor positioned on the display screen using an input device is utilized to fix a reference location for the panning operation. By moving the cursor on the display screen, a line between the cursor and the reference location is provided. The direction of the line indicates direction of the panning operation, while the length of the line determines speed of the panning operation.
