Lisa的電腦圖學 - week13

➤ Week13_匯出模型

1 - 開啟Maya，將al.obj模型拉進場景，分別選取頭、身、手、腳
2 - 點選File ➝ Export Selection ➝ Desktop ➝ Cancel

➤ Week13_綜合練習

1 - 下載git-2.30.0.2-64-bit.exe，將2023graphicsa叫到桌面

        cd desktop 進入桌面

        git clone https://github.com/happylisaya/2023graphicsa把雲端複製下來

        2023graphicsa

        start .

2 - 將freeglut複製進Final_Project，把lib裡的libfreeglut.a複製貼上，重新命名為libglut32.a

3 - Project ➝ Properties ➝ Project's build options ➝ Search directories ➝ Compiler 將路進改成freeglut\include，Linker 將路進改成freeglut\include，最後File ➝ Save Everything

4 - 右鍵notepad++開啟.gitignore檔案，在.a、.lib前加入#，就可以註解掉

5 - 將模型拉進新建的model資料夾

➤ Week13_模型匯入、組合

1 - 將week10_glm_gundam裡的glm.cpp、glm.h複製進Final_Project專案裡

2 - 右鍵Add files ➝ glm.cpp，最後File ➝ Save Everything

3 - 修改main.cpp程式碼
