A.期中考
B.複習：移動,旋轉,縮放
C.主題：T-R-T旋轉

1.  一樣到這個網站
https://www.transmissionzero.co.uk/software/freeglut-devel/
下載Download freeglut 3.0.0 for MinGW

2.再到這個
http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/
載 date win32 glut32.dll

3. 三角形可以旋轉的程式

#include <GL/glut.h>
float angle=0;
void display()
{
    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
    glPushMatrix();
        glTranslatef(0,0.5,0);
        glutSolidTeapot(0.3);
    glPopMatrix();
    glPushMatrix();

    glPopMatrix();

    glPushMatrix();
        glTranslatef(0.50,0.625,0);
        glRotatef(angle,0,0,1);
        glTranslatef(0.6,0,0);

        glRotatef(-90,0,1,0);
        glutSolidCone(0.2,0.6,30,30);
    glPopMatrix();
    glutSwapBuffers();
}
void motion(int x,int y)
{
    angle = x;
    display();
}
int main(int argc,char**argv)
{
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
    glutCreateWindow("week10 TRT");

    glutDisplayFunc(display);
    glutMotionFunc(motion);

    glutMainLoop();
}
