Question: I have some objects on the screen and would like to rotate only one of them. I tried using the glRotatef(...) function but turns out glRotatef(...) rotates all my objects (rotates the camera, maybe?).
How can I rotate only one?

I use openGL ES 1.1

Answer: 
You need the rotation to be in effect only when the geometry you're interested in is being drawn.

```
... draw stuff ...
glPushMatrix();
glRotatef(angle, 0, 1, 0);
... draw rotated stuff ...
glPopMatrix();
... draw more stuff ...

```
[Tutorial #4 from NeHe](http://nehe.gamedev.net/tutorial/rotation/14001/) shows how to do that precisely.
