先安裝OpenCV,然後建立glut專案
再把執行目錄改到你的工作資料夾
改執行目錄不只可以從notepad++改
也可以從CodeBlocks裡面改喔
要把鋼彈的模型(OBJ)丟進去glut專案裡面
首先要把"要匯入的部位"的obj,mtl丟到同一個目錄中
再來要把老師給的網址的source裡面的glm.h, glm.cpp丟進去
最後在glut專案右鍵add file把glm.cpp加進去
就可以執行囉
剛剛在丟OBJ,MTL檔的時候
也有把Diffuse(材質)丟進去
要用到之前第10週教的,把貼圖讀進來
如果縮放都用glmUnitize()/// -1...+1
這樣子身體會跟腳一樣大,不合理
所以我們不用glmUnitsize()而是用glmScale()
