1. A multi-mode parallel graphics rendering and display system capable of real-time graphics rendering and display operations using a graphics hub device, said multi-mode parallel graphics rendering and display system comprising: CPU memory space for storing one or more graphics-based applications and a graphics library for generating graphics commands and data (GCAD) during the run-time of the graphics-based application; one or more CPUs for executing said graphics-based applications; and a multi-mode parallel graphics rendering system (MPGRS) supporting multiple modes of parallel operation selected from the group consisting of object division, image division, and time division, and said MMPGRS including (i) a plurality of graphic processing pipelines (GPPLs) supporting a parallel graphics rendering process that employs one or more of said object division, image division and/or time division modes of parallel operation in order to execute graphic commands and process graphics data and render pixel images containing graphics for display on a display device during the run-time of said graphics-based application, and wherein each mode of parallel operation includes at least a decomposition stage, a distribution stage and a recomposition stage; (ii) a decomposition module for supporting the decomposition stage of parallel operation; (iii) a distribution module for supporting the distribution stage of parallel operation; (iv) a recomposition module for supporting the recomposition stage of parallel operation; (v) a graphics hub device (GHD) for interconnecting said CPU memory space with said GPPLs, and supporting basic functionalities of said distribution and recomposition modules during the run-time of said graphics-based application; and (vi) an automatic mode controller for automatically controlling the mode of parallel operation of said parallel graphics rendering subsystem during the run-time of said graphics-based application.
