Abstract
A single logical screen computer display uses multiple remote computer systems operable to perform hardware accelerated 3D graphics operations. The display system includes a client process, a first slave host computer coupled to first display hardware, a second slave host computer coupled to second display hardware, and a network broadcast path between the client process and the first and second slave host computers. The client process is operable to broadcast OGL command buffers to the first and second slave host computers using the network broadcast path. The first and second slave host computers are operable to execute OGL commands in the OGL command buffers and to render the results on the first and second display hardware, respectively. First and second X server processes run on the first and second slave hosts, and first and second OGL daemon processes also run on the first and second slave hosts. The network broadcast path bypasses the X server processes, thereby providing greatly enhanced 3D graphics performance over the network.
