劉電腦圖學 Week11

week11 鍵盤、音樂、滑鼠、轉動

第一堂課

開一個新GLUT專案week11-1_keyboard

Ctrl+f 找到glutKeyboardFunc(key);

程式碼#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot( 0.3 );

    glutSwapBuffers();

}

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

{

    if( key == 27 ) exit(1234);

}

int main (int argc, char** argv)

{

     glutInit(&argc, argv);

     glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

     glutCreateWindow("week11");

     glutDisplayFunc(display);

     glutKeyboardFunc(keyboard);

     glutMainLoop();

}

開新的GLUT專案week11-2_keyboard_playsound==>按鍵盤可撥放聲音

#include <windows.h>

#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    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();

}

第二堂課

開啟新的空白文件

week11-3_PlaySound.cpp

加入playSound咒語 winmm

#include <windows.h>

#include <stdio.h>

int main()

{

     ///PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\do.wav", NULL, SND_SYNC);

     ///PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\re.wav", NULL, SND_SYNC);

     ///PlaySound("C:\\Users\\Administrator\\Desktop\\do-re-mi\\mi.wav", NULL, SND_SYNC);

     

     ///目錄的斜線可以用 兩個反斜線\\ 或是一個斜線/

     PlaySound("do-re-mi/do.wav" , NULL, SND_SYNC);

     ///相對路徑 Relative path

     printf("Hello World\n");

}

開新專案week11-4

新增幾行程式

#include "CMP3_MCI.h"

CMP3_MCI myMP3;

char filename[] = "C:/Users/Administrator/Desktop/do-re-mi/suzume.mp3";

 myMP3.Load(filename);

 myMP3.Play();

第三堂課

改目錄位置
