| Abstract: | Analyses a new kind of hardware-implementation architecture based on its C-like hardware developing environment and multi-thread mechanism, and realizes the mathematical image map of geometric distortion correction on the bases of CPU. The experiments, based on different resolutions, show that the algorithm can enhance the interactive rendering velocity and the simulation reality. |
