Real-Time Generating and Rendering Technology of Reality Scene

Real-time rendering of reality scene is one of the difficulties for visual system of flight simulator. This paper introduces a technology that large remote sensing satellite image as texture and DEM data are used in generating reality scene and IRIS Performer develop tool is used in real-time rendering reality scene. Scene is divided into cells with the methods of partition range and multi-resolution model. The concept of many layer models in a cell is brought. The dynamic data partition and schedule strategy based on view point is presented. The reality scene of real-time rendering has been used with this method in our flight simulator .The experiment results show that the visual effect is perfect.
