Method and system for providing useable images on a high resolution display when a 2D graphics window is utilized with a 3D graphics window
First Claim
1. A graphics pipeline for use with a high resolution display comprising:
- a frame buffer configuration, the frame buffer configuration including a first mode area and a second mode area; and
a display pipeline for obtaining data from the frame buffer configuration, the display pipeline including a controller, the controller for providing pixels from the first mode area to the display as is and the controller for expanding pixels from the second mode area and providing the expanded pixels to the display,wherein the first mode area comprises an under sampled area that corresponds to a 3D graphics window, and the second mode area comprises a non under sampled area that corresponds to a 2D graphics window on the display.

Abstract
A graphics pipeline for use with a high resolution display is disclosed. The graphics pipeline comprises a frame buffer configuration. The frame buffer configuration includes a first mode area and a second mode area. The graphics pipeline further includes a display pipeline for obtaining data from the frame buffer configuration. The display pipeline includes a controller. The controller provides pixels from the first mode area to the display as is. Finally, the controller expands pixels from the second mode area and provides the expanded pixels to the display. Accordingly, a system and method in accordance with the present invention solves the GUI problem (small icon and small menu text) of high resolution display by allowing the 3D Graphics Window to display fine pitch pictures while being able to display images in the 2D graphics window in a useable form. The system and method in accordance does not depend on the types of drawing objects (line or surface), drawing order, and crossover.

7. A display pipeline comprising:
-
a controller for receiving pixels information from a super sample anti aliasing (SSAA) frame buffer configuration, the controller having a first mode and second mode, the first mode for allowing the controller to operate in a super sampling mode and the second mode for allowing the controller to operate in an under sampling model, wherein in the under sampling mode the controller provides pixels from an under sampled area in the frame buffer configuration to the high resolution display as is and expands the pixels from a non under sampled area in the frame buffer configuration and provides the expanded pixels to the display, and wherein the under sampled area corresponds to 3D graphics window on the display and the non under sampled area corresponds to a 2D graphics window on the display. - View Dependent Claims (8, 9, 10)
