電腦圖學課程week11 叡

 

Week11-1

CodeBlocks開啟,glut專案,命名week11-1_keyboard

 打程式碼出現水壺

#include <GL/glut.h>

void display()

{

    glutSolidTeapot( 0.3 );

    glutSwapBuffers();

}

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

{

    if(key==27) exit(0);

}

int main(int argc, char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week11");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMainLoop();

}

Week11-2

CodeBlocks開啟,glut專案,命名week11-2_keyboard_wav

複製第一個程式碼並修改

#include <windows.h>

#include <GL/glut.h>

void display()

{

    glutSolidTeapot( 0.3 );

    glutSwapBuffers();

}

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

{

    if(key=='1') PlaySound("C:\\Users\\Administrator\\Desktop\\do_re_mi\\do.wav", NULL , SND_ASYNC);

    if(key=='2') PlaySound("C:\\Users\\Administrator\\Desktop\\do_re_mi\\re.wav", NULL , SND_ASYNC);

    if(key=='3') PlaySound("C:\\Users\\Administrator\\Desktop\\do_re_mi\\mi.wav", NULL , SND_ASYNC);

}

int main(int argc, char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week11");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMainLoop();

}

按鍵盤123會出現對應的音高

Week11-3

Ctrl+Shift+s 儲存所有

關掉,然後直接開一個檔案

#include <windows.h>

int main()

{

    PlaySound("C:\\Users\\Administrator\\Desktop\\do_re_mi\\do.wav", NULL , SND_ASYNC);

    PlaySound("C:\\Users\\Administrator\\Desktop\\do_re_mi\\ra.wav", NULL , SND_ASYNC);

    PlaySound("C:\\Users\\Administrator\\Desktop\\do_re_mi\\mi.wav", NULL , SND_ASYNC);

    PlaySound("C:\\Users\\Administrator\\Desktop\\do_re_mi\\fa.wav", NULL , SND_ASYNC);

    PlaySound("C:\\Users\\Administrator\\Desktop\\do_re_mi\\so.wav", NULL , SND_ASYNC);

}

Week11-4

再創一個GLUT專案   命名為week11-4_GLUT_mp3   可播放MP3音樂

#include "CMP3_MCI.h"

CMP3_MCI myMP3;

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

{

    char filename[] = "C:/Users/Administrator/Desktop/do_re_mi/suzumi.mp3";

    myMP3.Load(filename);

    myMP3.Play();///step02-2播放

    glutInit(&argc, argv);

    glutInitWindowSize(640,480);

    glutInitWindowPosition(10,10);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

把week11-4_glut_mp3.cbp改了

把freeglut.dll跟suzumi.mp3放進檔案就可以播放音樂
