Libgdx I can't find glScalef method in GL

So I have little problem here. I know that libgdx allows you to access to low level OpenGL methods or something like. But I can’t find glScalef method. So why I can’t use glScalef? or maybe I just did not noticed the method. ???

LibGDX uses cameras with matrices. Look into using cameras and you should be able to scale, rotate, and translate the camera’s matrix.

Ok, I will try. Thanks for fast answer.

Are those not OpenGL 1.x functions?

I think now you just scale by a matrix yourself.

EDIT: LibGDX only supports OpenGL 3.0 now.
