古利夏醫生的艾爾迪亞日記 week11

week11明天就要實體上課了

glm模型相關複習

freeglut裝好 lib/bliglut32.工作目錄

opencv2裝好

opencv->Setting-compiler-search directories 目錄 compiler include目錄

opencv->Setting-compiler-search directories 目錄 Linker lib目錄

opencv->Setting-compiler-search directories 目錄 cv210 cxcore2210 highgui210目錄

File-New-Project,GLUT專案 桌面 week11_gundam

放 myGundam.zip的模式檔data 到 freeglut\bon\data..

程式碼

#include <GL/glut.h>

#include <opencv/highgui.h>

int main()
