1.學會用timer函式
先利用Timer讓聲音在幾秒鐘出來

去wav網站上下載聲音
要記得把聲音檔放在 in C:\Users\user\Desktop\freeglut\bin 裡



程式碼
#include <GL/glut.h>
#include <mmsystem.h>///NOW (0)發聲音
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSwapBuffers();
}
void timer(int t)///NOW (2)
{
    glutTimerFunc(1000, timer, 0);///NOW2間隔一秒持續撥放
    PlaySoundA("Femaleha.wav", NULL, SND_ASYNC);///NOW (2)
}
int main(int argc, char**argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutInitWindowSize(500,500);///大一點
    glutCreateWindow("week14 timer");

    glutDisplayFunc(display);
    glutTimerFunc(1000, timer, 0);///NOW (1)
1000代表一秒鐘

    glutMainLoop();
}


#include <GL/glut.h>

#include <mmsystem.h>///NOW (0)發聲音
#include <stdio.h>
float angle=0;
void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glPushMatrix();
        glRotatef(angle,0,0,1);
        glutSolidTeapot(0.3);
    glPopMatrix();
    glutSwapBuffers();

}

void timer(int t)///NOW (2)

{

    glutTimerFunc(30, timer, t+1);///NOW2間隔一秒持續撥放
    printf("現在的 timer的T是:%d\n",t);
    ///PlaySoundA("Femaleha.wav", NULL, SND_ASYNC);///NOW (2)
    angle=t;
    glutPostRedisplay();
}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutInitWindowSize(500,500);///大一點

    glutCreateWindow("week14 timer");



    glutDisplayFunc(display);

    glutTimerFunc(1000, timer, 0);///NOW (1)

///1000代表一秒鐘



    glutMainLoop();

}
2.內插公式

程式碼
#include <GL/glut.h>

#include <mmsystem.h>///NOW (0)發聲音
#include <stdio.h>
float angle=0;
float nowX=0;
void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glPushMatrix();
       /// glRotatef(angle,0,0,1);
       glTranslated(nowX,0,0);
        glutSolidTeapot(0.3);
    glPopMatrix();
    glutSwapBuffers();

}

void timer(int t)///NOW (2)

{

    glutTimerFunc(30, timer, t+1);///NOW2間隔一秒持續撥放
    printf("現在的 timer的T是:%d\n",t);
    ///PlaySoundA("Femaleha.wav", NULL, SND_ASYNC);///NOW (2)
   /// angle=t;
   float alpha=(t%30)/30.0;
   nowX = alpha*1.0+(1-alpha)*-1.0;
    glutPostRedisplay();
}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutInitWindowSize(500,500);///大一點

    glutCreateWindow("week14 timer");



    glutDisplayFunc(display);

    glutTimerFunc(1000, timer, 0);///NOW (1)

///1000代表一秒鐘



    glutMainLoop();

}
