🔴更改設定 讓CBP檔變成不是不明的檔案






🔴更改工作目錄，改成小數點.

🔴再將freeglut.dll放到專案目錄裡


🔴到老師的網站下在[data][source]
然後解壓縮[data]和[source]

🔴再把data的[al.mtl][al.obj][porsche.mtl][porsche.obj]丟到專案目錄裡

🔴再把source的[glm.h][glm.c]丟到專案目錄裡
再將[glm.c]改檔名變[glm.cpp]

🔴到codeblocks的專案上面add files 把[glm.cpp]加進來


🔴秀出超大的領帶

🔴加上汽車模型當作手臂

🔴可以旋轉的右手臂

🔴加上上手臂和下手臂

🔴可以旋轉的上下手臂

🔴做完右手在做左手

🔴兩隻手都有上下手臂，但轉動角度都一樣很奇怪


🔴讓上下手臂能分開轉動 分別按0123
