【課堂作業二】
jsyeh/3dcg10/ 如前週操作指示開啟
glTranslatef(x,y,z);
glRotatef(角度,x,y,z);
glScalef(x,y,z);
調整旋轉方向和角度
看右手手指的旋轉方向
【課堂作業三】

glClear(GL_COLOR_BUFFER_BIT);
glTranslatef(0, 0.1, 0);
glColor3f(1,0,0);
glutSolidTeapot(0.3);
glutSwapBuffers();
}
int main(int argc,char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("Hello 3D");
glutDisplayFunc(display);
///glutMouseFunc(mouse);
glutMainLoop();
}
