打開GLUT

讓模型旋轉(改變成茶壺)

glPushMatrix();

        glTranslated(-2.4,1.2,-6);

        glRotated(60,1,0,0);

        glRotated(a,0,0,1);

        glutSolidTeapot(1);

    glPopMatrix();

打光 Light Material.exe

CodeBlock. File - New Project - GLUT

3D Model . (glm.h(glm.c改glm.cpp)

放到 :
     (A)#include "glm.h"
     (B)GLMmodel * pmodel = NULL;
     (C)畫模型

陣列 ...[ ] = {...};

                   ...[ ] = {...};
                   ...[ ] = {...};
                   ...[ ] = {...};
                   ...[ ] = {...};
                   ...[ ] = {...};
                   ...[ ] = {...};
                   ...[ ] = {...};
                   ...[ ] = {...};

勾勾要拿掉!
