《古今数学思想》是数学史的经典名著，初版以来其影响力一直长盛不衰。著作可谓博大精深，洋洋百万余言，阐述了从古代直到20世纪头几十年中的数学创造和发展，特别着重于主流数学的工作。大量一手资料的旁征博引，非常全面地提及各个历史时期的数学家特别是知名数学家的贡献，是《古今数学思想》的一大特色。《古今数学思想》所关心的还有：对数学本身的看法，不同时期中这种看法的改变，以及数学家对于他们自己成就的理解。本书体现了作者的深厚功力。

If you want to learn about 3D math in order to program games or graphics, then this book is for you. There are many books out there that promise to teach you how to make a game or put cool pictures up on the screen, so why should you read this particular book? This book offers several unique advantages over other books about games or graphics programming:
A unique topic. This book fills a gap that has been left by other books on graphics, linear algebra, simulation, and programming. It is an introductory book, meaning we have focused our efforts on providing thorough coverage on fundamental 3D concepts — topics that are normally glossed over in a few quick pages or relegated to an appendix in other publications (because, after all, you already know all this stuff). Our book is definitely the book you should read first, before buying that “Write a 3DVideoGame in 21Days” book. This book is not only an introductory book, it is also a reference book — a “toolbox” of equations and techniques that you can browse through on a first reading and then revisit when the need for a specific tool arises. 1
A unique approach. We take a three-pronged approach to the subject matter: math, geome- try, and code. The math part is the equations and numbers. This is where most books stop. Of course, the math is important, but to make it powerful, you have to have good intuition about how the math connects with the geometry.We will show you not just one but multiple ways to relate the numbers with the geometry on a variety of subjects, such as orientation in 3D, matrix multiplication, and quaternions. After the intuition comes the implementation; the code part is the practical part.We show real usable code that makes programming 3D math as easy as possible.
Unique authors. Our combined experience brings together academic authority with in-the-trenches practical advice. Fletcher Dunn has six years of professional game program- ming experience and several titles under his belt on a var
