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.

[ What is claimed is:] [1.]1. A method for performing 3D graphics operations on a logical screen that comprises composited outputs from multiple computer graphics pipelines, the method comprising the steps of:providing a client process, a master server process and a plurality of slave server processes wherein each slave server process is operable to drive one of the pipelines;in the master server process, dividing the logical screen among the slave server processes by storing a different set of x/y offset information for each of the slave server processes;in the client process, switching to a logical screen mode in which 3D graphics API commands issued by an application are buffered;in the client process, buffering a set of 3D graphics API commands issued by the application;using a network, flushing the same buffered set of 3D graphics API commands to hosts of all of the different slave server processes; andin each of the slave server processes, processing the flushed set of 3D graphics API commands differently responsive to x/y offset information received from the master server process.
