The Delphi Developers Guide to OpenGL is aimed at the intermediate/advanced Delphi programmer who wishes to extend their programming expertise to the field of 3D graphics. Whilst there many books available on Delphi which give an introduction to graphics programming, few of these attempt to go beyond anything more than a rudimentary level of understanding.
Jacobs, on the other hand, has written a book which provides many of the key ideas that are essential to developing 3D graphics applications. From an introduction that deals with setting up the OpenGL environment, to texture mapping and animation, this book treats the subject with a fluid style, and occasional humour. This is a first class introduction to graphics which every Delphi programmer should own!

As a complete newbie to OpenGl but not to Delphi, I found problems in the first chapter of the book. The first program, although it compiled and ran without error, would not display the dark green colour. Going on to Chapter 2, I found the extra command, glflush; back to the first program and add glflush, the program now works OK. A frustrating start. The viewport explanation is not very clear. It ignores the fact that the Delphi Form comes between the viewport and windows. I hope the rest of the book is better.
I am using Windows XP Home and Delphi 6 & 7 and an ATI 9800 video card. Maybe this combination is too new for the books programs, but OpenGL is supposed to be platform and program independent. I shall persevere - 3 stars because I haven't finished the book, I hope it improves!
