这个代码不算成熟，但是可以读取一般的3DS文件了，还有重现时物体材质没有精心设计，这里请阅读的朋友自行设计吧。这个例子的目的是给刚学的朋友提供一个例子，代码如下： 3dsId.h #ifndef _3DS_ID_H_
#define _3DS_ID_H_ const GLsizei PRIMARY = 0x4D4D;
const GLsizei MAINOBJECT = 0x3D3D; // 网格对象的版本号
const GLsizei EDITKEYFRAME = 0xB000; // 所有关键帧信息的头部
const GLsizei MATERIAL = 0xAFFF; // 保存纹理信息
const GLsizei OBJECT = 0x4000; // 保存对象的面、顶点等信息
const GLsizei MATNAME = 0xA000; // 保存材质名称
const GLsizei OBJECT_MESH = 0x4100; // 新的网格对象
const GLsizei OBJECT_VERTICES = 0x4110; // 对象顶点
const GLsizei OBJECT_FACES = 0x4120; // 对象的面
const GLsizei OBJECT_MATERIAL = 0x4130; // 对象的材质
const GLsizei MAT_AMBIENT = 0xa010;
const GLsizei MAT_DIFFUSE = 0xa020;
const GLsizei MAT_SPECULAR = 0xa030;
const GLsizei MAT_SHININESS = 0xa040;
const GLsizei MAT_TRANSPARENCY = 0xa050;
const GLsizei INT_PERCENTAGE = 0x0030;
const GLsizei FLOAT_PERCENTAGE = 0x0031;
const GLsizei COLOR_F = 0x0010;
const GLsizei COLOR_24 = 0x0011; #endif MyModel.h #ifndef __MY_MODEL_H__
