OpenGL in Delphi

I’m not sure if it is the right forum so please forgive me if it isn’t
I know the basics of OpenGL and I was working with Delphi for more then 2 years.
I have OpenGL.dcu and OpenGl.pas and I added them to the uses clause and all work perfect. I notise also that including OpenGL in uses, i include wgl librari. I write code and I compile it but nothink is displayed. I can render openGL surface only through the GLScene library. It it posible to draw OpenGL surface to the form without GLScene or any other external Library
Thank You
P.S. I’m using Borland Delphi 6
