This Book focuses on DirectX applications. if you ever tried writting your own vertices , planes ,....etc. this is the book you need to use the already built in features of Direct-X , even if you are an OPEN_GL programmer. i mixed the structures and data types in DirectX with the existing Open GL programs to reduce the code. i feel sorry i did not read this book before, it is like reading the mind of a graphics programmer and tell you what you need in the next page. i recommend this book for any one started programming 3D and wants to make a quick advance or wants to modify the macaroni codes he created and wants to simplify it extreamly and get a better performance (both Direct3D or Open GL).
