Query: Not good at all

This book barely scratches the surface of what a book on DirectX should. It's a shame that this is all we Delphi people have. My advice is toi go buy a book on C++ and a DirectX book (that uses C++) and just convert the examples (Plenty of people online would probably be able to help with that. All of the DirectX units and headers have been translated into Delphi).
