Week12 三個ㄌ 的 上課筆記

1.播放音樂mp3檔

使用 CMP3_MCI.h 便可以輕鬆地將 MP3檔播放出來。

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

(2) CMP3_MCI myMP3;///(2) 宣告一個變數,叫 myMP3

在 main()函式裡面

(3) myMP3.Load("C:\\dropbox\\yukai.mp3"); /// "C:/dropbox/yukai.mp3"

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

2.觀察濾鏡

茶壺使用濾鏡

#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);

    //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 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_ambient[]    = { 0.7f, 0.7f, 0.7f, 1.0f };

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;

}
