空客A320计算机三维模型的构建

摘要我们国家各大航空公司喜欢用A320型号的飞机进行中短途飞行，因此本次对该型号飞机模型的建立具有较强的现实意义，这是因为可以将模拟出的结果科学合理的应用到现实的多个领域中。与二维的模型相比，三维模型的精确度、还原现实的程度比较高，在各行业的实用性也会比较强，比如：医学中常用的器官模型都是三维立体模型：建筑中为了将构想出的中的风景、建筑设计出来。就需要利用模拟图形：在游戏中可以利用三维模型，将游戏的精美程度提高程度。本次研究则是将该项技术与现实环境相结合，从而拓宽三维模型技术的使用渠道。本次研究的实现需要利用一个技术支持软件-Multigen Crestor.该软件的优点在于即使在规模很大的场景中使用也不会出现卡顿的情况，这是因为该软件可以通过压缩精度的方式将模型的数量控制在一个比较小的范围，并且该技术为了将模型的逼真程度提高方法市通过对阴影、光照等因素的调整。并且该软件还拥有DOF技术，该技能可以通过将模型从静态调整为动态将模型维持在比较高的范围，因此，在设计规模较大的虚拟环境时一般利用该软件进行绘制。关键词：虚拟现实：A320:三维模型：逼真度AbstractMajor airlines in our country like to use A320 aircraft for medium and short haulflights.Therefore,the establishment of this aircraft model has strong practical significance,because the simulated results can be scientifically and reasonably applied to many practicalfields.The accuracy of the 3D model is higher than that of the 3D model,which iscommonly used in the medical industry;In order to design the landscape and architecturein architecture.We need to use simulation graphics;In the game,three-dimensional modelscan be used to improve the beauty of the game.This research is to combine this technologywith the real environment,so as to broaden the use channels of 3D model technology.Theimplementation of this research needs to use a technical support software--MultiGenCrestor The advantage of the software is that even in large-scale scenes,there will be nojamming,because the software can control the number of models in a relatively smallrange by means of compression accuracy,and the technology can improve the fidelity ofthe model by adjusting the factors such as shadow and light.Moreover,the software alsohas DOF technology,which can maintain the model in a relatively high range by adjustingthe model from static to dynamic.Therefore,the software is generally used to draw whendesigning large-scale virtual environment.Key words:virtual reality;A320;3D model;fidelity目录第1章绪论11.1研究背景及意义…1.2国内外研究现状1.2.1国外研究现状1.2.2国内研究现状..21.3三维模型在民航中的应用及前景..31.4研究方法31.5研究框架及内容.….3第2章空客A320计算机三维模型的构建42.1建模工具及方案….52.1.1建模工具的对比与选择2.1.2 Multigen Creator简介..52.1.3总体建模方案设计….62.2飞机整体外部模型构建..62.2.1机身建模.…62.2.2其他零部件的建模..92.2.3多个模型的合并.….102.3模型数据库的支持与优化.…。112.4光照、材质、纹理贴图的使用132.5小结.….13第3章飞机起落架动画的制作.143.1D0F技术的介绍..153.2使起落架可以收放的具体操作.153.3小结….16第4章总结.17参考文献.…18致谢.19附录：外文翻译资料.20
