世界上最短的基于DXUT框架的第一人称摄像机例子，d3d的例程中的代码很长， 笔者就只想用其中的第一人称摄像机，花了好几天研究了多个相关例程，抽出 其中的摄像机，改写了最简单的摄像机例子，在学习d3d的坐标变换中晕头的弟兄们 哈哈... -The world s shortest DXUT framework based on first-person camera example, d3d code of the routine is very long, I

个人所写matlab代码，应用三维坐标变换原理在空间中模拟行星运动轨迹。其中涉及3维作图，图形object，矩阵变换等等。-Written by myself, the use of three-dimensional coordinate transformation principle in space simulation of the planet s trajectory. Which involves three-dimensional mapping, graphics objec
