🎃6z0的筆記 Week09

 此週程式碼請參閱(Github)

glColor改變顏色

glTexCoord改變貼圖位置 glVertex改變頂點

OpenCV下載安裝

0. 下載 OpenCV 2.1.0 (moodle有上課檔案)

1. PATH 要設定成第二個Add PATH...

2. 安裝在預設位置 C:\OpenCV2.1

-------------------------------------------------------------------------------------------------------------------

城市

0. 安裝好 OpenCV後 重開 CodeBlocks 

1. File-New-EmptyFile 存成 week09_opencv.cpp

2-1.Search directories -> Compiler ->  Add：C:\OpenCV2.1\include

2-2. Search directories -> Linker ->  Add：C:\OpenCV2.1\lib

2-3. Setting-Compiler Setting -> Linker setting  Add：cv210/cxcore210/highgui210

3.輸入程式碼：

#include <opencv/highgui.h>

int main()

{ 

IplImage * img = cvLoadImage("檔名.png"); // ("  ")內放想要秀出的的圖片檔名

cvShowImage("week09", img); //秀出圖片

cvWaitKey(0); //按任意鍵繼續

}

⚠️要注意程式碼的圖片檔名是否正確及路徑 否則會叫不出來⚠️

4.Build and run 秀出圖片

常用10行程式碼

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

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

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week09 texture");

    

    glutDisplayFunc(display);

    glutMainLoop();

}
