Sean的電腦圖學日誌 week15

 week15

架環境

'''cpp

#include <windows.h>

#include <GL/glut.h>

int main()

{

    PlaySound("filename.wav", NULL, SND_SYNC);

    //等待播完音樂,才結束

}

'''

使用wav.，NO mp3!!

音檔放在C:\Users\Administrator\Desktop\freeglut\bin

改工作目錄

複製音檔和freeglut.dll到專案資料夾

改工作目錄:右鍵專案properties>Build targets>Excecution working dir(改成.)

#week15-2_CMP3_MCI

1.File-New-Project, GLUT專案, 15-2_CMP3_MCI

2.老師準備了 CMP3_MCI.h 傳給你了, 請放在桌面上的week15-2_CMP3_MCI目錄裡

'''

#include <stdio.h> //為了scanf()

#include "CMP3_MCI.h" //記得要用雙引號,不能用角括號

CMP3_MCI myMP3; //宣告一個變數,名字叫 myMP3

int main()

{

    myMP3.Load("filename.mp3");

    myMP3.Play();

    int a;//幫忙卡住, 程式不要快速結束

    scanf("%d",&a);

}

'''

##week15-2_CMP3_MCI_sample

1.File-New-Project,GLUT專案,week15-2_CMP3_MCI_sample

2.把CMP3_MCI.h 放在同一個目錄 week15-2_CMP3_MCI_sample

3.不要刪177行的範例

'''cpp

#include "CMP3_MCI.h"

CMP3_MCI myMP3;

'''

再插入

'''cpp

    myMP3.Load("檔名.mp3");

    myMP3.Play();

'''

##week15-3_mouse_motion_glTranslatef_glRotatef

1.File-New-Project, GLUT專案

2.貼上11行GLUT簡單版本

'''cpp

#include <GL/glut.h>

float angleX[15]={}, angleY[15]={};

void display(){

    ///glClearColor(1,1,0,1);///黃色背景

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glTranslatef(angleX[14]/150.0,-angleY[14]/150.0,0);///移動速度

        glRotatef(angleX[0],1,0,0);

        glRotatef(angleY[0],0,1,0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

}

int angleID=0,oldX=0,oldY=0;

void mouse(int button,int state,int x,int y){

    oldX=x;

    oldY=y;

}

void motion(int x,int y){

    angleX[angleID]+=x-oldX;

    angleY[angleID]+=y-oldY;

    oldX=x;

    oldY=y;

    glutPostRedisplay();

}

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

    if(key=='x')angleID=14;

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week15-3");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);///等一下會有程式放這裡

    glutMouseFunc(mouse);

    glutMotionFunc(motion);

    glutMainLoop();

}
