摘要： A system for rendering graphical data utilizes a plurality of graphics pipelines, a first process, and a second process. Each of the plurality of graphics pipelines is configured to render graphical data. The first process is configured to receive three-dimensional (3D) graphics commands from a graphics application and to receive input commands from a user input device. The first process is configured to buffer the received 3D graphics commands and to execute the received input commands, and the first process, for each of the buffered 3D graphics commands, is configured to begin processing a newly received command upon buffering the 3D graphics command. The second process is configured to interface the buffered graphics commands with each of the plurality of pipelines, wherein execution of the user input command affects an object defined by the graphics application.
