The Three-dimensional Display System In Launch Field

Base on the application requirements of Informationization Construction, Thisarticle design the Three-dimensional display and terrain visualization system by the3DS Max and OpenGL graphics software.The command-and-control site is the center of Milford Proving Ground, publicdisplay system is an important part of the center. It is the base of domestically andabroad, window, is a platform to show the level and strength of the base, richingdisplay content, improving command ways and the methods, acting key function forplatform show, have great significance to improve base image and influence. In viewof the current public display drab, content poor, intuitive is not strong shortcomings,this project through3d technology intuitive an accurate reflection of the aircraftreal-time situation, including feature points, injection, Satellite on board, navigatingzone3d display. Have strengthened mission real time display accuracy, perceptionvivid, offer the important basis for chief fast and accurate command decision.This paper first analyzes the system’s present situation in a shooting rangedomestic, this paper introduces the model three dimensional display and terrainvisualization related theory, and then on the basis of the3d model display andcontrol and terrain visualization of the key technology on the analysis, the studymainly includes the following four aspects:(1) Build aircraft model and import OpenGL platform to display, through thecoordinate transformation, vertex vector calculation and texture mapping technologyrepresent the realistic3d model.(2) Display control. Based on the track ball technology to achieve the scene tothe manual control.(3) For the quadtree LOD simplified algorithm analysis research, Mainlyincludes the quadtree stratified and storage, node evaluation standard, dynamic gridgeneration of crack eliminate and cutting technology, etc(4) In the aboving research,wo design and realized the3d display system, thesystem can be intuitive performance of aircraft flight movements and state.
