为什么在不同的视区中显示不一样呢?

void display(void)
{
glClear (GL_COLOR_BUFFER_BIT);
glColor3f (0.9, 0.8, 0.9);



//glMatrixMode(GL_MODELVIEW);
glLoadIdentity (); /* clear the matrix */
/* viewing transformation */

gluLookAt (0.0, 0.0, 5.0, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0);
/* modeling transformation */


//glTranslatef(0.0,0.0,-5.0);
//glRotatef(45.0,0.0,1.0,0.0);
glScalef (1.0, 2.0, 1.0);


glMatrixMode (GL_PROJECTION);
glLoadIdentity ();
//glFrustum (-1.0, 1.0, -1.0, 1.0, 1.5, 20.0);
gluPerspective(75.0,1.0,1.5,20.0);

glViewport(0,0,100,100);
glutWireCube (1.0);


glViewport(100,0,200,100);
glutWireCube(1.0);

glViewport(200,0,300,100);
glutWireCube(1.0);

glFlush ();

}

能把glInit和glResize的代码贴出来吗，不明白你的意思
