Research On Dynamic Modeling In The 3D Terrain

The terrain of the battlefield is not an inflexible static environment, and it is a dynamic scene changing along with time. The dynamic changes of terrain in battlefield will cause the occurrence of many abrupt affairs and condition , it also immediately bring the huge influence to the command and decision , even more it brings the change of the war situation . The dynamic changes need to be show immediately and truly in Virtual Battlefield, then can support actual combat. Therefore, to depict the dynamic changes of terrain in battlefield imitation is an urgent problem needs to be resolved. This paper mainly studies the dynamic terrain modeling, the main research contents is as follows:1, According to the research of domestic and international, the paper points out the great significance of terrain dynamic modeling . 2, Analyzing the performance method of 3D terrain dynamic modeling and it's characters, and set the point to the terrain dynamic modeling based on the change of space data .3, Introduce methods for terrain dynamic modeling according to Grid and Tin(Triangulated Irregular Network).4, The paper puts forward a kind of method to terrain dynamic modeling based on partial construction of Tin, and study some relevant arithmetic. Based on experimental result, it gets some conclusions about terrain dynamic modeling aim at applications.This paper develops some trial studies about the dynamic terrain model. There are more problems need to be resolved in the future study.
