Verfahren und Vorrichtung zum Ablegen dreidimensionaler Bilddaten in einem Rahmenpufferspeicher

摘要

The invention relates to a method for filing picture data for 3-D display of imagery on a screen in a frame buffer memory, which has a storage location for each pixel constituting said imagery. The pixel data contains position information on each pixel in relation to the storage location in the frame buffer storage, depth information indicating the physical distance of the pixel to be displayed in relation to a viewer, and at least display information on the respective pixel. A plurality of pixel data can exist for each pixel. For all pixels constituting said imagery, the inventive method provides for initial filing (34, 36, 38, 40) of depth information on all pixel data in the storage location allocated thereto for each pixel in the frame buffer storage, the depth information indicating thereby the shortest physical distance between the pixel to be displayed and the viewer.
