VC++ 结合OpenGL 实现.obj mesh文件的读取，并设有摄像机调整等功能-VC++ combine OpenGL implementation obj mesh file read and has a camera adjustment functions

网格简化程序，将标准的obj三维模型文件简化成为包含三角面片较少的三维模型，之后通过opengl显示出来。采用的主要算法为边坍缩算法。-Mesh simplification of procedures, the obj 3D model file standard simplified 3D model contains triangles become less, then through the OpenGL display. The main algorithm uses edge co
