Abstract: A hybrid method or apparatus for processing OpenGL display list commands. A deamon intercepts display list commands issued by a client to an OpenGL stack. Responsive to a newList [list commands] endList sequence: the daemon stores a representation of a first subset of the list commands; and creates, in the stack, a display list corresponding to a second subset of the list commands. Responsive to a callList command: the daemon issues to the stack at least one immediate mode command corresponding to the first subset of the list commands and at least one callList command invoking the display list corresponding to the second subset of the list commands. The daemon may also store a representation of an expression or function. Responsive to the callList command, the daemon may evaluate the expression or function and conditionally change the step of invoking the display list based on the outcome.

Abstract: Single Logical Screen and Direct Hardware Access in a 3D environment are combined by passing a single stream of protocol to the X Server, which in turn passes the information to multiple 3D rendering processes for display on individual screens (monitors). Multiple instances of a single daemon implement the rendering processes. The X Server communicates with an instance of the daemon functioning as a master daemon, which in turn controls the remaining instances functioning as slave daemons. All daemons communicate through common shared memory segments. This achieves both efficiency and performance, since duplicated distribution of commands and data is avoided. Each of the daemons is driven by the contents of the shared memory segments. To facilitate this, an X Client, the X Server and the daemons are all interconnected with separate control and data paths.

Abstract translation: 将单一逻辑屏幕和直接硬件访问通过将单个流协议传递到X服务器来进行组合，X服务器又将信息传递到多个3D渲染过程，以便在各个屏幕（监视器）上显示。 单个守护程序的多个实例实现呈现过程。 X服务器与作为主守护进程的守护程序实例进行通信，后者又控制剩余的实例作为从站守护程序。 所有后台程序通过共享内存段进行通信。 这样可以实现效率和性能，因为避免了重复分发命令和数据。 每个守护进程由共享内存段的内容驱动。 为了方便这一点，X客户端，X服务器和守护程序都与单独的控制和数据路径互连。

Abstract: A system rendering graphical data from a graphics application utilizes a plurality of frame buffers, a plurality of graphics pipelines, and logic. Each of the graphics pipelines is configured to render graphical data to a different one of the frame buffers. The logic is configured to determine a mode of operation of the graphics application and to prevent, based on the mode of operation of the graphics application, at least one of the graphics pipelines from rendering the graphical data from the graphics application.

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.

Abstract: A graphical display system utilizes a plurality of graphics pipelines to render data to a display device. More specifically, the graphical display system utilizes a first graphics pipeline, a second graphics pipeline, a compositor, and a display device. The first graphics pipeline renders a first portion of a graphical command, and the second graphics pipeline renders a second portion of a graphical command. The compositor receives the first and second portions of graphical data and interfaces the first and second portions with the display device. The display device then displays an image based on the first and second portions of graphical data respectively rendered by the first and second graphics pipelines. By enabling a plurality of graphics pipelines to render different portions of graphical data to the same display device, the speed and/or image quality associated with the image displayed by the display device can be improved.

Abstract: A graphical display system utilizes a plurality of graphics pipelines to efficiently display a jitter enhanced image. More specifically, the graphical display system utilizes a plurality of graphical pipelines, a compositor, and a display device. Each of the graphical pipelines receives and renders graphical data. In rendering the graphical data, each of the graphical pipelines mathematically combines a different offset to coordinate values included within the graphical data. The compositor receives the graphical data rendered by the plurality of pipelines and blends color values associated with corresponding coordinate values within the graphical data. The compositor also interfaces the blended color values with the display device, which displays an image based on at least the blended color values. As a result, graphical data defining a jitter enhanced image is efficiently rendered to the display device.
