A complete answer would depend on what type of projection you wish to accomplish. There are various type of projections including orthogonal (which will not give you a sense of distance, but which is easiest to implement) and various angular algorithms. One start would be to check out

http://www.gamedev.net/reference/list.asp?categoryid=40

but there are many resources available if you search the internet. This site has a few articles on using OpenGL as well.

I would add that cross-posting is by no means a nice practice.

The same thread (http://www.codeguru.com/forum/showthread.php?s=&threadid=215123) has gotten a good answer in the Visual C++ thread.

This is not to say that galathaea's answer is not good though ;)

Sorry:(
