Week12_嗯對,這是賴小沫的

 1_用Console application專案執行mp3播放

先從FB社團裡下載CMP3_MCI.h檔

 

使用老師傳送的檔案

 

 音樂檔&CMP3_MCI.h檔放進同一目錄

 

按下F9即可執行播放音樂

 

試著自己新增一個專案來播放mp3

File－New－Project...

選擇新增一個Console application專案

 

 記得要設定專案名稱及存放的路徑，以免找不到檔案

 

 開啟main.cpp會看到預設程式碼

 

複製FB中老師給的程式碼步驟

 

直接貼上，並修改每行程式碼的位置

   註：要記得將CMP3_MCI.h和mp3檔複製進新創的專案資料夾中

#include <iostream>

#include "CMP3_MCI.h"   //放在同一個程式碼專案的目錄中

CMP3_MCI myMP3;   //宣告一個變數

using namespace std;

int main()

{

    myMP3.Load("yukai.mp3");  //讀入mp3，要放在同一個程式碼專案的目錄中

    myMP3.Play();  //播放讀入的mp3檔

 

    int n;

    cin >> n;  //要卡住，否則程式輸出結果，音樂就會停了

    cout << "Hello world!" << endl;

    return 0;

}

在專案名稱按下滑鼠右鍵，選擇Build options...

在Linker settings的Link libraries中加入winmm，這樣待會才能順利執行

 

按下F9(Build&Run) 即可播放出音樂

 

 2_用GLUT專案執行mp3播放

新增一個GLUT專案：File－New－Project...

選擇GLUT project

記得要設定專案名稱及存放的路徑，以免找不到檔案

從FB社團中下載freeglut，並複製存放路徑

貼上剛剛複製的freeglut資料夾路徑

直接按下Finish即可

複製FB中老師給的程式碼步驟

直接貼上，並修改每行程式碼的位置

   註：要記得將CMP3_MCI.h和mp3檔複製進新創的專案資料夾中

 

按下F9(Build&Run) 即可播放出音樂 

 

 3_執行Projection.exe

從 jsyeh.org/3dcg10 下載windows.zip,data.zip,glut32.dll

將windows.zip解壓縮,將data資料夾與glut32.dll拉進windows資料夾

開啟Projection.exe

調整gluLookAt的數值，並觀察攝影機的運鏡效果

 

 4_gluLookAt攝影機運鏡

使用老師傳送的檔案

 

開啟專案檔

 

控制攝影機運鏡

   gluLookAt(eyeX,eyeY,eyeZ,centerX,centerY,centerZ,upX,upY,upZ);

 

#include <GL/glut.h>
float eyeX=0, eyeY=0, eyeZ=1;
float centerX=0, centerY=0, centerZ=0;
float upX=0, upY=1, upZ=0;

{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glColor3d(1,0,0);

    //攝影機運鏡的設定
    glPushMatrix();
        gluLookAt(eyeX, eyeY, eyeZ,
                  centerX, centerY, centerZ,
                  upX, upY, upZ);
        glutSolidTeapot(0.3);
    glPopMatrix();
    glutSwapBuffers();
}

const GLfloat high_shininess[] = { 100.0f };

/* Program entry point */
int main(int argc, char *argv[])
{
    glutInit(&argc, argv);
    glutInitWindowSize(640,480);
    glutInitWindowPosition(10,10);
    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("GLUT Shapes");

    ///glutReshapeFunc(resize);
    glutDisplayFunc(display);
    ///glutKeyboardFunc(key);
    ///glutIdleFunc(idle);

    glMaterialfv(GL_FRONT, GL_SPECULAR,  mat_specular);
    glMaterialfv(GL_FRONT, GL_SHININESS, high_shininess);

    glutMainLoop();
    return EXIT_SUCCESS;
