1..jsyeh.org/3dcg10/ 下載sources,data,windows，執行Light Material.exe
2.windows.zip >> 下載windows >> 解壓縮到 >> Light Material.exe

2. glTranslatef(x,y,z);//移動
3. glRotatef(角度, x,y,z);//轉動
4. glScalef(x,y,z);//縮放
5. glBegin(GL_POLYGON);//開始畫
6. glColor3f(r,g,b);//色彩
7. glTexCoord2f(tx, ty);//貼圖座標
8. glNormal3f( nx,ny,nz);//打光法向量
9. glVertex3f(x,y,z);//頂點
10. glEnd();//結束畫
11. glPopMatrix(); //還原矩陣
