聲音 (音效、音樂)

!!注意!!音檔記得要放在freeglut的bin資料夾內!!

1.撥放單個音檔

#include <windows.h>

#include <stdio.h>//標準輸出輸入

int main()

{

   PlaySound("so.wav",NULL,SND_SYNC);//等待音檔播完再撥下一個

}

2.撥放多個音檔

char a;

 while(1){

        a=getchar();//讀入字串

        if(a=='1')PlaySound("do.wav",NULL,SND_ASYNC);

        if(a=='2')PlaySound("re.wav",NULL,SND_ASYNC);

        if(a=='3')PlaySound("mi.wav",NULL,SND_ASYNC);

        if(a=='4')PlaySound("fa.wav",NULL,SND_ASYNC);

        if(a=='5')PlaySound("so.wav",NULL,SND_ASYNC);

    }

if(a=='1')PlaySound("do.wav",NULL,SND_ASYNC);

如果a等於1播放do其他以此類推

SND_SYNC//等待音檔播完再撥下一個

SND_ASYNC//直接撥放

2-1結合圖形

#include <windows.h>

#include <GL/glut.h>

static void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

(使用鍵盤撥放聲音)

void KEYBOARD(unsigned char key, int x, int y)

{

        if(key=='1')PlaySound("do.wav",NULL,SND_ASYNC);

        if(key=='2')PlaySound("re.wav",NULL,SND_ASYNC);

        if(key=='3')PlaySound("mi.wav",NULL,SND_ASYNC);

        if(key=='4')PlaySound("fa.wav",NULL,SND_ASYNC);

        if(key=='5')PlaySound("so.wav",NULL,SND_ASYNC);

}

(使用滑鼠撥放聲音)

void Mouse(int button,int state,int x,int y){

    if (state==GLUT_DOWN)PlaySound("shot.wav",NULL,SND_ASYNC);

}

(呼叫函式)

int main(int argc, char *argv[])

{

   glutInit(&argc, argv);

   glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

   glutCreateWindow("GLUT10");//視窗名

   glutDisplayFunc(display);//顯示

   glutKeyboardFunc(KEYBOARD);//鍵盤

   glutMouseFunc(Mouse);//滑鼠

   glutMainLoop();//讓他一直呼叫

}

3.使用CMP3_MCI mp3在背景播放mp3檔

打光 Lighting

#include <windows.h>

#include <stdio.h>

int main()

{

    char c;

    while(1)

    {

        c=getchar();

        if(c=='1') PlaySound("do.wav",NULL,SND_ASYNC);

        if(c=='2') PlaySound("re.wav",NULL,SND_ASYNC);

        if(c=='3') PlaySound("mi.wav",NULL,SND_ASYNC);

        if(c=='4') PlaySound("fa.wav",NULL,SND_ASYNC);

        if(c=='5') PlaySound("so.wav",NULL,SND_ASYNC);

        if(c=='6') PlaySound("la.wav",NULL,SND_ASYNC);

        if(c=='7') PlaySound("si.wav",NULL,SND_ASYNC);

        if(c=='8') PlaySound("do2.wav",NULL,SND_ASYNC);

        if(c=='9') PlaySound("star.wav",NULL,SND_ASYNC);

    }

}

#include <GL/glut.h>

static int slices = 16;

static int stacks = 16;

static void display(void)

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

const GLfloat light_ambient[]  = { 0.0f, 0.0f, 0.0f, 1.0f };

const GLfloat light_diffuse[]  = { 1.0f, 1.0f, 1.0f, 1.0f };

const GLfloat light_specular[] = { 1.0f, 1.0f, 1.0f, 1.0f };

const GLfloat light_position[] = { 2.0f, 5.0f, 5.0f, 0.0f };

const GLfloat mat_ambient[]    = { 0.7f, 0.7f, 0.7f, 1.0f };

const GLfloat mat_diffuse[]    = { 0.8f, 0.8f, 0.8f, 1.0f };

const GLfloat mat_specular[]   = { 1.0f, 1.0f, 1.0f, 1.0f };

const GLfloat high_shininess[] = { 100.0f };

int main(int argc, char **argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("GLUT Shapes");

    glEnable(GL_DEPTH_TEST);

    glDepthFunc(GL_LESS);

    glEnable(GL_LIGHT0);

    glEnable(GL_NORMALIZE);

    glEnable(GL_COLOR_MATERIAL);

    glEnable(GL_LIGHTING);

    glLightfv(GL_LIGHT0, GL_AMBIENT,  light_ambient);

    glLightfv(GL_LIGHT0, GL_DIFFUSE,  light_diffuse);

    glLightfv(GL_LIGHT0, GL_SPECULAR, light_specular);

    glLightfv(GL_LIGHT0, GL_POSITION, light_position);

    glMaterialfv(GL_FRONT, GL_AMBIENT,   mat_ambient);

    glMaterialfv(GL_FRONT, GL_DIFFUSE,   mat_diffuse);

    glMaterialfv(GL_FRONT, GL_SPECULAR,  mat_specular);

    glMaterialfv(GL_FRONT, GL_SHININESS, high_shininess);

    glutDisplayFunc(display);

    glutMainLoop();

}

再改一下數值就可以改變打光的位置了!
