Study of Dynamic Scheduling Strategy for Large-Scale Terrain Visualization in Flight Simulation System

Analyze the characteristic of three-dimensional scene visualization and regulation of scene change in flight simulation system, which is the basis of implementation of terrain reconstruction. Give the related mathematics model of terrain visualization. In order to resolve the problem that three-dimensional scene could not be reconstructed fast because of large-scale terrain data, present a procedure of integrated culling based on state-tree from simplification, and present a terrain data dynamic schedule framework from render optimization. For the suggested optimized procedure and framework, give a experiment and conclusion based on programming, it prove that the suggested dynamic schedule strategy in this paper could fast construct three-dimensional scene in flight simulation, could speed up the three-dimensional visualization, it could meet the practical requirement of engineering in flight simulation.
