Han Week13

 ##Week13

#week13-1_glm_gundam_keyboard_angleID_mouse_motion_angle

0.freeglut安裝

1.OpenCV2.1安裝

2.重開CodeBlocks,設定Complier-Setting的3個設定

###CodeBlocks:Setting-Complier裡,要加入Opencv相關的3個設定

###=>C:\OpenCV2.1\include

###=>C:\OpenCV2.1\lib

###=>cv210 cxcore210 highgui210

再把上周的week12-3_glm_gundam_keyboard_angleID_mouse_motion_angle程式碼拿來用

0.改目錄名,改,cbp名,用Notepad++開啟.cbp檔改內容將week12-3都改為week13-1

1.修改程式碼

##week13-2_FILE_fopen_fprintf_fscanf

1.把week13-1複製整個目錄,改目錄名改.cbp檔,Notepad++改裡面的Title

2.要加FILE指標

‵‵‵cpp

#include<stdio.h>

FILE * fin = NULL;

FILE * fout=NULL;

‵‵‵

3.在motion()裡,要加一段程式

```cpp

void motion(int x,int y){

angle[angleID]+=y-oldY;

oldX=x;

oldY=y;

glutPostdisplay();

if(fout==NULL)fout=fopen("angle.txt","w+");

for(int i=0;i<20;i++){

    printf("%.1f "",angle[i]);

    fprintf(fout,"%.1f ",angle[i] );

}

printf("\n");

fprintf(fout,"\n");

}

```

你執行程式時,用mouse motion 一邊改變角度,一邊大量產生角度值小黑關掉後,可在目錄裡,看到angle.txt裡面就是剛剛印的一堆數值小心,angle.txt 裡面要有空格,不然就錯了。printf()及fprintf()要加"%.1f "
