how can i rotate a cube in an efficient way ???!!!!

[Nader El Masry]

i know that many people may see this topic bit strange,but of course the problem is not to rotate a cube actually.

i made an application to rotate a cube and i know that it is very simple one but the problem that when i rotate the cube it rotate the (X,Y,Z) axis with it !!!!
u can see it when i rotate the cube with angle 90 around Y-axis then when i rotate around X-axis it rotate around Z-axis because i rotate the axis with the cube ?!!!
Sample of the Code :
Gl.glPushMatrix();
Gl.glScalef(45, 45, 45);
Gl.glRotatef(cubeAngley, 0, 1, 0);
Gl.glRotatef(cubeAnglex, 1, 0, 0);
DrawCube();
Gl.glPopMatrix();

private void Oglctrl_KeyDown(object sender, KeyEventArgs e)
{
// rotating cube
if (e.KeyCode == Keys.W)
{
cubeAnglex -= 5;
}
else if (e.KeyCode == Keys.S)
{
cubeAnglex += 5;
}
else if (e.KeyCode == Keys.A)
{
cubeAngley -= 5;
}
else if (e.KeyCode == Keys.D)
{
cubeAngley += 5;
}
}

Thinking of rotation as rotation from a programmers point of view is probably not correct. You are not rotating anything, once you grab that its easier to optimize things.

The watcher/observer is percieving things being rotated, but you shouldnt use that term as a programmer. Once you get rid of that term as a programmer it will also open up new ways to do things. You will only limit yourself when you put general terms to your philosophy and code.
