開啟貝殼專案

#include <stdio.h>
FILE*fout=NULL;
int main(){
    fout=fopen("filename.txt","w+");
    for(int i=0;i<20;i++){
        fprintf(fout,"Hello World\n");
    }
}

這樣就會在資料夾裡面多一個文件檔

#include <stdio.h>
FILE*fout=NULL;
float angle[20];
int main(){
    fout=fopen("motion.txt","w+");
    for(int i=0;i<20;i++){

    }
}

貼圖

先用這個，下載opencv2.1
https://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.1/OpenCV-2.1.0-win32-vs2008.exe/download

建立一個新的project

程式碼

#include <opencv/highgui.h>
int main()
{
    IplImage * img=cvLoadImage("image.jpg");
    cvShowImage("opencv Window",img);
    cvWaitKey(0);

加入一張圖片

完美

在開一個新的project

然後把之前茶壺的程式碼拿出來，再加上剛剛的那些程式碼加在一起

這個一樣要做剛剛那些很麻煩的動作，做完就有了

week06

到這http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/多下載一個新的這個source
，然後跟之前的步驟都一樣再來把source裡面的glm.cpp,glm.h,lightmaterial.c拿出來
把上次的程式碼拿出來加上黃色的部分，再把freeglut的資料夾裡面的lib的資料夾打開，
把data的資料夾丟進去程式碼要讀到#include "glm.h"的話要把glm.h的檔案放到放到codeblock新增的資料夾，再來打開codeblock在這上面點右鍵，點這個然後把glm.c改名成glm.cpp加進去，這樣就好了。
