WEEK12  課堂der筆記筆記 

課堂作業1~~~妖怪mp3

1.開啟codeblocks，新增一個Console application專案

2.至圖學FB下載CMP_3檔案，並自行下載一個mp3音樂檔

3.將兩個檔案拉至專案資料夾中

4.程式碼如下:

#include <iostream>

#include "CMP3_MCI.h"

CMP3_MCI myMP3;

using namespace std;

int main()

{

    myMP3.Load("yukai.mp3");

    myMP3.Play();

    int n;

    cin >> n;

    cout << "Hello world!" << endl;

    return 0;

}

5.執行結果(播出音樂)

6.輸入0，結果輸出Hello world!

課堂作業2~~~角度茶壺

1.開啟codeblocks，新增一個GLUT專案

2.程式碼如下:

#include <GL/glut.h>

float eyeX=-0.5, eyeY=0, eyeZ=0;     //調整攝影角度-0.8~0.8

float centerX=0, centerY=0, centerZ=0;

float upX=0, upY=1, upZ=0;

static void display(void)

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glColor3d(1,0,0);

    glPushMatrix();

        gluLookAt(eyeX, eyeY, eyeZ,

                  centerX, centerY, centerZ,

                  upX, upY, upZ);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

}

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

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);

    glClearColor(1,1,1,1);
