本工程包含了使用各种API（Direct3D，OpenGL，GDI，DirectSound，SDL2）播放多媒体例子。 其中音频输入为PCM采样数据。输出至系统的声卡播放出来。 视频输入为YUV/RGB像素数据。输出至显示器上的一个窗口播放出来。 通过本工程的代码初学者可以快速学习使用这几个API播放视频和音频的技术。 一共包括了如下几个子工程： simplest_audio_play_directsound: 使用DirectSound播放PCM音频采样数据。 simplest_audio_play_sdl2: 使用SDL2播放PCM音频采样数据。 simplest_video_play_direct3d: 使用Direct3D的Surface播放RGB/YUV视频像素数据。 simplest_video_play_direct3d_texture:使用Direct3D的Texture播放RGB视频像素数据。 simplest_video_play_gdi: 使用GDI播放RGB/YUV视频像素数据。 simplest_video_play_opengl: 使用OpenGL播放RGB/YUV视频像素数据。 simplest_video_play_opengl_texture: 使用OpenGL的Texture播放YUV视频像素数据。 simplest_video_play_sdl2: 使用SDL2播放RGB/YUV视频像素数据。 1.1版修复了一些问题

会有一个小飞机，可以用键盘操作，用它来消灭敌人，用到了简单的碰撞检测的技术

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
