ww-week13-綜合練習_作業: (你的)模型擺Pose

 1.裁切模型、組模型：

在https://jsyeh.org/3dcg10/中下載[data][win32]兩個檔案 / 在資料夾中開啟後分別解壓縮 / 將data資料夾放到window裡 / 

開啟MAYA/Import/匯入:al.obj / 分別裁切上手臂、下手臂、頭、身體 / file / Export Selection匯出選擇的物件/

小葉老師上課軟體下載git / 將2023graphicsa clone 下來

在codeblocks 開啟2023Grahhicsa 的Final_Project / file / open 開啟.cbp檔

將freeglut加入Final_Project專案裡(為了解決每次都要安裝freeglut的問題)

/並更改freeglut裡的libfreeglut.a複製一個改名為libglut32.a

在專案上面右鍵Properties / Project's build options/

更改兩個工作執行目錄的位置改成相對路徑/compiler和linker都要記得改

修改.gitignore清單，把.lib 和.a註解調解鎖(檢查.dll是否有解鎖)

在第10週用的glm.cpp 和 glm.h 都複製到你的Final_Project專案裡 / 在專案裡Add File把glm.cpp加進去 / save everything / 在FinalProject內新增modle資料夾 / 將剛切好的身體部位複製進去

開始畫出模型 / 先印身體

調整大小並印出頭

用鍵盤控制物件的顯示加入keyboard函式(將之前寫得先註解掉)

加入滑鼠移動功能可以幫助移動到畫面中心，並印出位移量可以幫助之後做TRT時需要的移動

更改gitignore內確認是否有將.obj(3Dmodel檔) .dll(libfreeglut.dll) .a .lib(freegult內的lib目錄)解鎖 / 記得save everything
