GLOrtho and scale

Hi there!
I am using GlOrthi projection and for zooming into the model i use glScale. Is there an other possibility, because i don’t like glScale. In Perspective projection i use moving the camera.

I think there isn’t more posibilities.
Why you don’t like glScale?
If you are using a camera you can assign the coordinates to place it with gluPerspective, if you put the camera near of your obsects they’ll be bigger.

You could also change the values you pass to glOrtho in order to get a “zoom” effect.
