今天內容: 打光、3D模型OBJ、GLM讀入OBJ

/1/ 先下載解壓縮[data][win32] glut32.dll  source
在桌面創一個windows的資料夾，把解壓縮後的data、win32、glut32.dill 、source放進去

/2/到 https://www.transmissionzero.co.uk/software/freeglut-devel/
下載 Download freeglut 3.0.0 for MinGW 並解壓縮

/3/將freeglut資料夾的libfreeglut複製貼上 並改名為 libglut32.a

/4/在codeblocks開啟一個project
並將source裡的glm.c glm.h貼到codeblocks的資料夾內(glm.c改成glm.cpp)

/5/在codeblocks內的專案按右鍵選擇 Add files 選擇glm.cpp
會加入一個程式碼

/6/將data資料夾放進freeglut裡的bin資料夾即可

/7/執行程式碼

**程式碼**
