Caterpillar To Rockets Training Ground Driving Simulation System Automatic Generation Technology Research

In daily training, computer graphics has played a great applicational role. It is a meaningful task to generate various training grounds automatically thorugh computer graphics.Through combining with the red situation of training of troops,this paper focuses on theoperating system task of driving training simulation of the crawler self-propelled gun.to improve the reality of daily training of officers and soldiers and to decrease the differene.between simulath and a ctual combat to a minimum point,and even to adieve the generating and implemetfatary tech nology of driving training ground.with simnlation operating system,Actually,there are two main key technology existing.in this task,first of all,the object includes envelope grid;second,loval texture.The following use the road and crater traing ground as the main objects of study,to analyze the driving training situation of crawler sef-propelled gun and mabe deep research ofspecific algorithms and the realization of technigues.It mainly contains the following four contents.First,using anew local management algorithm of inregular terrain to inodify the relevant data of any point on the simulational terrain grid.and to whiere the imperovement of the efficiency of the algorithm.Second,concerning the model,the author puts forward the read model based on the framework structure, at the same time proposes the algorithm of construcfion of polygonal envelope grid,and realize the construction and further building of envelope grid of rood and craters.through modeling the contour of objiects,and baseed on the re-editing of the triangular surface.Third,based on the road wheel model,the author decompose rectangle and isosceles trapezoid,so as to realize the gimple algorithm of texture coordinates,and texture mapping of road.Tex ture mapping of intersection is mainly through the method of extracting intersectional point,texture mapping of the main eraters adopts the perinciple of spherical mapping to achieve.Finally,this paper realize the algorithm through Direct X9.0and Visual C++6.0 put info application in real simulational training system,and validate the effeciveness of the algorithm.
