I am new to OpenGl. I am making a 3D Graph inside a rectangular widget(ince, I am using QT). What I am not understanding is - What are the OpenGl coordinate units?
I know the width and the height of the dialig box/widget, but the 3D Graph which I am drawing inside it, is using it’s own units, thereby I am not in control of the graph. Actually I am scaling the 3D figure, but since I don’t know the units of opengl, I am not able to do it.
Any help from you guys would be highly esteemed.
Thanks s much
