Design And Implementation Of The Aircraft Of Visual Simulation Platform Based On Unity 3D

In recent years,the domestic and international military institutions and institutes and universities in the world have carried out in-depth research on the aircraft,and the research on the simulation of the aircraft comes to a new stage.This thesis according to the demand of hypersonic aircraft,fixed wing UAV,rigid liquid coupling of complex spacecraft aircraft such as visual simulation tasks(focusing on marine aircraft and fixed wing UAV scene,and at the same time)the status of today’s virtual scene simulation software combined,puts forward the design architecture of the Unity 3D aircraft scene based on Simulation platform.The visual simulation platform based on modular idea visual simulation software is divided into the aircraft flight scene database,model base,database,man-machine interaction action module library,based on the idea of design,improve a variety of aircraft models,set up suitable for all kinds of aircraft flying scenes,interactive operation to perform various flight demonstration action by computer.To sum up,the thesis mainly completed the following work:1.The research status of visual simulation at home and abroad is investigated and analyzed,including the analysis of the current mainstream game engine for visual simulation.In this thesis,the advantages and characteristics of Unity 3D game engine are described in detail,and through comparison,it is concluded that the Unity 3D game engine is used to develop the aircraft visual simulation platform.2.On the basis of modular design idea,the aircraft model library and the flight scene library are constructed firstly.The aircraft model library combines the 3DS MAX with Google SketchUp,and improves the model through the Unity 3D particle system,and gets the visualization model of the aircraft with higher degree of reduction.At the same time,terrain rendering technology and shader technology are used to construct flight scenarios suitable for different aircrafts.3.The design of the primary way of action to the scripting library module,can realize the flight scenario demonstrates a variety of scenarios,including different aircraft loading different flight scene,formation transformation,animation design,target tracking and target etc.4.As a part of the visual display software,people can directly operate,and the design of rich human-computer interaction can provide a good user experience.In addition to the basic user interface operation,human-computer interaction can also be realized by the mouse,keyboard,mobile touch and voice operation.In this thesis,a variety of human-computer interaction operations are realized through the corresponding technology,which enriches the interactive design module library.
