关于Wolfgang Engel：
Wolfgang EngelWolfgang was working for the last fouryears in Rockstar's core technology group as the lead graphicsprogrammer. Now he is taking a sabbatical to do some research intonext-gen graphics. He is the editor of the ShaderX books, the author ofseveral other books and loves to talk about graphics programming. He isalso a MVP DirectX since July 2006 and active in several advisoryboards in the industry.
作为一个中国的程序员，我对他的印象是他是游戏程序开发领域的大牛，著有一本很好的学习Direct3D的入门书籍《Beginning Direct3D Game Programming, Second Edition》，同时他也是关于GPU编程的ShaderX系列丛书的主编。

祝他研究出更炫目的图形技术。

可能是受前一阵Szulborski去世的影响吧
干这行就是在奔命
