| 摘 要： | 介绍了通过loft建模方法创建飞机模型、如何由max文件转换成3ds文件、X文件以及X文件加载的全过程。着重介绍了在转换、加载过程中模型的屏幕坐标和物体坐标之间的关系,各种文件转换时的开关量的设置。论述了以四元数法调整模型的屏幕坐标和物体坐标的方法。针对加载过程中飞机各个活动部件与飞机机体出现夹角的问题设计了一种快速有效的解决算法。

| Abstract: | How to create plane model with loft- method ,convert max-files to 3ds-file,X-file and the whole process of X-file loading are introduced. The relationship between screen-coordinate and object-coordinate of plane model during the process of conversion and loading, and the switch's setting during the course of conversion of several files are described especially. The method of adjusting screen-coordinate and object-coordinate of plane model with quaternion is discussed. A fleet and effective arithmetic of solving problem of inclination between kinetic plane parts and the plane body during the course of loading is put forward. |
