開啟maya / 裁切模型
去到https://jsyeh.org/3dcg10/
下載 1.[data] 2.[win32] 兩個檔案 並且解壓縮win32
將data丟進解壓縮後的windows 找到al.obj檔案 匯入maya(file / import)
將模型檔案打開後 / 裁切(選取)他的身體 / 分別匯出(file / export selection)
1.head.obj 2.body.obj 3.uparmR.obj 4.lowarmR.obj
下載git指令 開啟git bash
步驟如下：1.cd desktop 2.git clone https://github.com/你的帳號/2023graphicsa3.cd 2023graphicsa 4.start .
去到codeblocks開舊專案 file-open 點選fianl project 的 project.cbp
把freeglut目錄解壓縮在我們fianl project 裡頭
記得要將裡頭lib的libfreeglut.a複製並貼上將複製的改檔名為libglut32.a
File - Open - 檔案.cbp 開啟檔案
開啟檔案 在檔案上按右鍵
點選edit 更改路徑 freeglut\include
點選edit 更改路徑 freeglut\lib
去到2023graphicsa資料夾內找到gitignore檔案 按右鍵 開啟notepad++
找到.a .lib在前方加#
去到Final Project 裡的freeglut / bin 的.dll檔複製
去到第10週 將glm.cpp glm.h檔案複製到Final Project專案裡
點選專案按右鍵 Add File 把glm.cpp加進去
File -Save- everything 才會存檔 不然會備份到(還沒存檔的舊黨內)
把剛剛裁切好的模型複製到Final Project專案裡頭 新增的model資料夾

可以移動右上手臂 可以移動它到中心點 並且可以得知位置
去到gitignore檔案內 用notepad++ 將obj註解掉 因為我們要備份obj模型 並儲存
最後git push上傳雲端
