week05 合併倒數第二個好開心之圖學

 week05

今天教open cv的使用

1.OPENCV 前置設定

Install opencv2.1

安裝第三步 Add OpenCV to system PATH (中間的)

1.Setting-Compiler,目錄compiler->include 

2.Setting-Compiler,目錄linker->lib

3.Setting-Compiler,linker setting add cv210 cxcore210 highgui210

*貼圖程式碼

#include <opencv/highgui.h> ///Open的內建外掛
int main()
{
    IplImage * img = cvLoadImage("c:/micky.jpg");
    cvShowImage("img",img);
    cvWaitKey(0);
}

https://jsyeh.org/3dcg10/下載:1.data 2.win32->解壓縮win32 , 把data資料夾->windows資料夾

*茶杯和貼圖整合一起放出

#include <GL/glut.h>

#include <opencv/highgui.h>

void display()

{

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc, char *argv[])

{

    IplImage * img = cvLoadImage("c:/micky.jpg");

    cvShowImage("img",img);

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week05-1 Texture");

    glutDisplayFunc(display);

    glutMainLoop();

}

*地球茶杯

#include <opencv/highgui.h> ///使用 OpenCV 2.1 比較簡單, 只要用 High GUI 即可

#include <opencv/cv.h>

#include <GL/glut.h>
