ABSTRACT:
A method for generalized flipping of pixmaps and other arrays of image data in a software display device interface for computer generated graphics applications. The display device interface enables application programs to create flipping surface structures representing on and offscreen pixmaps, textures, sprites, overlays, etc. The display device interface includes a flip function to control the flipping of these flipping structures. It also includes functions to synchronize access to the surfaces represented by the flipping structure. Applications and other processes can use these access synchronization functions to manipulate surfaces represented by the flipping structure without conflicting with a client's use of the surface. Clients other than the display controller can act as clients of the flipping operation. For instance, flipping structures can be used to implement video texture mapping, where the client of a texture flipping structure is a 3D rendering system.
