In order to overcome the limitations of those expensive projector systems,this paper discusses the Seamless Tiling Technology in a Large Scalable Multi-Projector Display System.Based on the open source technology OpenSceneGraph and Direct Show,three main technologies of display system are analyzed: distributed parallel rendering based on a cluster of personal computers using a well-defined synchronization technique,geometry calibration and color and light intensity blending.Further,in combination with specialized applications for large screen displays,the paper introduces a seamless large display system based on low cost personal computers and projectors.The experiment shows that the method is easy to operate and low cost.
