week10

 week10

下載data 和win32

下載source.zip

把gim.h放到week10_glm目錄裡

glm.c改檔名glm.cpp放到week10_glm

把glm.cpp道專案裡

把模型複製到bin資料夾裡

下載(桌面/葉正聖老師)裝OpenCV2.1

設定Setting_compiler

再重開Codeblocks

複製貼圖程式碼https://gist.github.com/jsyeh/5ed01210559721ec71b659b3ffed2dd7

加一行 myTexture("Diffuse.jpg");

glmDraw(pmodel, GLM_MATERIAL|GLM_TEXTURE);

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

#include <GL/glut.h>
