Abstract

Reality scene is one of the most basic and important technologies in visual system of flight simulators. It includes real terrain, terrain object and physiognomy. Nowadays, it is usually constructed with digital elevation model (DEM) and remote sensing satellite data. In spite of the fast development of computer hardware, it is very difficult to generate large area reality scenes in real-time. Therefore, model simplification, multi-resolution rendering and level of detail (LOD) become the hotspot of recent research. Multi-resolution rendering is the development and extension of the LOD, model simplification is the key in generating a lower resolution model from a complex higher one. Based on the manufacturing practice of some flight simulators, this paper discusses ways of reality scenes' generating and simplification, and dynamic data partition and schedule based on viewpoint.
