基于openGL的三阶魔方程序代码.docx

/*Magic2D.cpp文件：可以播放爱你一万年歌曲，需要在工程文件夹中新建文件夹“sound”并存放“爱你一万年.wav”文件需要在Data文件夹中上传y2.bmp到y7.bmp的图片，当然也可以在程序中相应部分自己修改该程序有两个文件，Magic2D.cpp和MoFang.cpp，可以实现三阶魔方任意层面的旋转并能使魔方在界面来回移动反弹，具体的建工程的步骤就不说了，祝大家好运*/#include MoFang.h#include /提供与多媒体有关的接口#pragma comment(lib, WINMM.LIB) /导入winmm.lib库,实现对多媒体编程的支持HDChDC=NULL;/ Private GDI Device ContextHGLRChRC=NULL;/ Permanent Rendering ContextHWNDhWnd=NULL;/ Holds Our Window Handleboolkeys256;/ Array Used For The Keyboard RoutineHINSTANCEhInstance;/ Holds The Instance Of The Applicationboolactive=TRUE;/ Window Active Flag Set To TRUE By Defaultboolfullscreen=TRUE;/ Fullscreen Flag Set To Fullscreen Mode By DefaultGLfloatxrot;/ X Rotation ( NEW )GLfloatyrot;/ Y Rotation ( NEW )GLfloatzrot;/ Z Rotation ( NEW )GLfloat RX=0;GLfloat RY=0;GLuinttexture7;/ Storage For One Texture ( NEW )GLboolean b_RX,b_RY;GLfloat turn_x=1,turn_y=1;LRESULTCALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);/ CALLBACK代表回调函数 Declaration For WndProc,函数声明，监听windowsAUX_RGBImageRec *LoadBMP(char *Filename)/ Loads A Bitmap ImageFILE *File=NULL;/ File Handleif (!Filename)/ Make Sure A Filename Was Givenreturn NULL;/ If Not Return NULLFile=fopen(Filename,r);/ Check To See If The File Existsif (File)/ Does The File Exist?fclose(File);/ Close The Handlereturn auxDIBImageLoad(Filename);/ Load The Bitmap And Return A Pointerreturn NULL;/ If Load Failed Return NULLvoid loadsound()PlaySound(sound爱你一万年.wav,NULL,SND_LOOP|SND_ASYNC|SND_FILENAME);int LoadGLTextures()/ Load Bitmaps And Convert To Texturesint Status=FALSE;/ Status IndicatorAUX_RGBImageRec *TextureImage1;/ Create Storage Space For The Texturememset(TextureImage,0,sizeof(void *)*1);
