Abstract: A 3D flight simulation and monitoring platform is established based on the technology of 3D terrain rendering, dynamic model drive and data fusion. The platform is supported by a aviation project. The primary purpose of the platform is to monitor and simulate the flight status in real-time. The development process of the platform is introduced and the method of 3D-Terrain is discussed. The simulating and monitoring results show that the platform is available and satisfied requirements. The 3D flight simulation and monitoring platform is also proved to be feasible and reliable.

Abstract: At present there are diverse algorithms in generating 3d terrain,to further improve the efficiency of the algorithms and fidelity of the 3d terrain,a new method generating 3d terrain by digital geographical topographic map was put forward.First extract the contour lines from the map and thin the contour lines by a improved thinning algorithm based on mathematical morphology[1].In the process of interpolation,the digital elevation map of terrain can be got by interpolation in vertical and horizontal directions,and the method of intra-interpolation and extra-interpolation according to the distribution of contour lines was also used.The terrain got by this method can reflect the details and the tendency of the terrain.The digital geographical topographic map on the network can reflect the change of the terrain timely because of its high updating speed.This method has great practical value

Abstract: The problem that the three-dimensional terrain data of Rendering was studied in Simulation and Game Engine .At first,a new real-time scheduling algorithm was put forward based on determining the simulation vision.in the visible area.the partition area was set up thought Level of Detail(LOD). Then setting up an adaptive node evaluation system was established based on distance and space error function. Through estimate plane of trangle render by layer,and adding the effort of rendering.
