There also could be relavent information here ->
http://cg.cs.tu-berlin.de/~ki/engines.html This is a list of 3D engines
sorted into lots of categories including a "Written in/for & Source" section
with a Delphi entry under it. Maybe someone elses 3D engine written in
Delphi, source provided, does what you want???
Wilfred, what are the "red and blue books"?

This is completely of the top of my head, but I think you want to get a hold
of the transformation matrix used to map the 3D co-ordinates onto the
screen. Use this yourself to transform your own 3d points to test them.
Have you got the red and blue books? They are excellent for learning
OpenGL.
There are a couple of good OpenGL resources for OpenGL on the net too
- Look up the delphi graphics page,
http://www.delphi-jedi.org/DelphiGraphics/jedi-index.htm
- GLScene by Mike Lischke is an excellent delphi object wrapper over OpenGL,
http://www.mind-link.com/glscene/ . I learnt a lot from that.
- And of course, the official home page, http://www.opengl.org
- There's some good tutorials on the MSDN as well.
Enjoy,
Wilfred.

Subject: [DUG]: Open GL question
Hi all,
I am just playing round (a little) with open GL.
One thing that I can't find out how to do is to get a 2D co-ordinate (in
pixels of the window client area) of a point in 3D space.
I want to know this so that I can tell when an object flies off my window.
Anyone have any ideas or pointers??
Regards
Colin Fraser
