Aimed to preview the effect of the creative stage and provide the accurate data to control the stage movement, the simulation and control system of dynamic stage set up a three - dimensional rendering and control engine to establish a three - dimensional and dynamic simulation model for the stereoscopic digital stage, based on the time - space framework. Not only can the system comprehensively present the effect of stage design, but can provide the accurate data including the state of stage and position data in the simulation process to precisely control the stage movement. By way of behavior modeling for the stereoscopic digital stage, the system conducts space analysis and calculation to the tableaux. It realizes the WYSIWYG rendering algorithm of stage design to show and evaluate the effect of the creative stage with high feasibility. According to the mechanical characteristics of the stereoscopic digital stage, the way of video editing method by projection decomposition and the way of parallel and poly - nuclear compu- ting are adopted to realize the recombination of those video data and to produce the video files meeting the needs of stage movement. In practice, the system can effectively improve the availability, reliability and efficiency of stage de- sign.
