    摘要： 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.

    摘要： A centralized resource system comprises a plurality of compute resource units, a plurality of visualization resource units, and a switching fabric coupling the plurality of visualization resource units to the plurality of compute resource units. The switching fabric is operable to couple select one or more visualization resource units to select one or more compute resource units for generating at least one graphical image. A plurality of display devices is coupled to the one or more select visualization resource units operable to display the at least one graphical image.

    摘要： A system for rendering graphical data utilizes a plurality of frame buffers, a plurality of graphics pipelines, a compositor, and logic. The plurality of graphics pipelines are configured to receive graphics commands and to render graphical data to each of the plurality of frame buffers based on the received graphics commands. The compositor is configured to receive a control signal and to interface the graphical data with a display device based on the control signal. The logic is configured to analyze the graphics commands and to make a determination, based on the graphics commands, as to which pixels defined by the graphical data are associated with three-dimensional (3D) regions. The logic is further configured to transmit the control signal to the compositor, wherein the control signal is based on the determination.

    摘要： 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.

    摘要： A modified display list contains a series of n nested bounding volumes. The first bounding volume in the series contains the remaining n-1 bounding volumes the series. The second bounding volume contains the remaining n-2 bounding volumes in the series, and so on. Upon invocation, the graphics display system processes the modified list sequentially and tests the bounding volumes as they are encountered. As soon as a bounding volume is encountered whose coordinates define a region that should not be rendered, further sequential processing of rendering commands in the list may be halted. If any state commands remain in the list, those commands or an equivalent set of state commands may be executed, and then processing of the list is complete. Alternatively, if push/pop state commands exist on either side of the list, then processing of the list may be halted without more.

    摘要翻译： 修改的显示列表包含一系列嵌套的嵌套卷。 系列中的第一个包围卷包含剩余的n-1个界限卷。 第二个界限卷包含系列中剩余的n-2个界限卷，依此类推。 在调用时，图形显示系统按顺序处理修改的列表，并在遇到遇到的范围内测试边界卷。 一旦遇到其坐标定义不应该呈现的区域的边界体积，则可能停止列表中渲染命令的进一步顺序处理。 如果列表中有任何状态命令，则可以执行这些命令或等效的状态命令集，然后完成列表的处理。 或者，如果在列表的任一侧上存在push / pop状态命令，则可以停止列表的处理。

    摘要： A system for providing a graphics tool access to a computer graphics system to evaluate and control a graphics application executing on the computer graphics system. The system includes application program interface (API) event generators for performing predetermined operations relating to a graphics library function call and for generating a hook event containing results of the predetermined operations; dispatch table manger for selecting an active dispatch table from a normal operations dispatch table having function pointer to the graphics library functions and a hooks dispatch table having pointer to the API event generators; and hook event manager for enabling and configuring selected ones of the API event generators in response to a graphics tool event request. The system further includes internal event generators, integrated along various locations of a graphics pipeline managed by the graphics library, for performing predetermined diagnostic operations in the graphics system. In this embodiment the hook event manager also enables and configures selected ones of the internal event generators.
