Week 12 彣禎的上課筆記

一.如何撥放MP3檔

(1)先去FB下載CMP3_MCI.h檔
 

(2)在開啟Code Blocks開啟專案

 

(3)把MP3檔放到專案資料夾

 

(4)輸入程式碼

#include <iostream>
#include "CMP3_MCI.h" ///(1) 放在同一個程式碼專案的目錄中哦

CMP3_MCI myMP3; ///(2) 宣告一個變數,叫 myMP3

using namespace std;

int main()
{
    myMP3.Load("yukai.mp3");  /// Load檔案   

    myMP3.Play(); /// (4) Play the file 播放   

    int n;
    cin>>n;
    cout << "Hello world!" << endl;
    return 0;
}

 

 

(5)按執行就會有聲音

 

(6)Google:youtube mp3 可找到轉換器

 

 

二.3D TRT轉動

 

三.矩陣.投影矩陣

(1)開啟GLUT專案

 

(2)開啟後，會出現一個茶壺

#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;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 light_ambient[]  = { 0.0f, 0.0f, 0.0f, 1.0f };
const GLfloat light_diffuse[]  = { 1.0f, 1.0f, 1.0f, 1.0f };
const GLfloat light_specular[] = { 1.0f, 1.0f, 1.0f, 1.0f };
const GLfloat light_position[] = { 2.0f, 5.0f, 5.0f, 0.0f };

const GLfloat mat_diffuse[]    = { 0.8f, 0.8f, 0.8f, 1.0f };
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);
    ///glEnable(GL_CULL_FACE);
    ///glCullFace(GL_BACK);

    glEnable(GL_DEPTH_TEST);
    glDepthFunc(GL_LESS);

    glEnable(GL_LIGHT0);
    glEnable(GL_NORMALIZE);
    glEnable(GL_COLOR_MATERIAL);
    glEnable(GL_LIGHTING);

    glLightfv(GL_LIGHT0, GL_AMBIENT,  light_ambient);
    glLightfv(GL_LIGHT0, GL_DIFFUSE,  light_diffuse);
    glLightfv(GL_LIGHT0, GL_SPECULAR, light_specular);
    glLightfv(GL_LIGHT0, GL_POSITION, light_position);

    glMaterialfv(GL_FRONT, GL_AMBIENT,   mat_ambient);
    glMaterialfv(GL_FRONT, GL_DIFFUSE,   mat_diffuse);
    glMaterialfv(GL_FRONT, GL_SPECULAR,  mat_specular);
    glMaterialfv(GL_FRONT, GL_SHININESS, high_shininess);

    glutMainLoop();

    return EXIT_SUCCESS;
}

(3)會有近大遠小的效果

四.攝影機運鏡

(1)到http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/ 下載三個檔案

 

(2)把Windows.zip解壓縮，並把data資料夾和glut32.dll放到Windows資料夾裡

(3)開啟Windows資料夾裡的Projection.exe

 

(4)開啟後，可以調整數字，觀察有什麼不一樣

 

 

　五.會動的機器人
