week11太會睡啦~~

1)首先下載3D檔案總管(3d exploration)免費試用版(學校安裝)


2)並在jsyeh.org/3dcg10下載data.zip並解壓縮在桌面

3)使用3d exploration去看data中的3D模型

匯出足球:

1)save as...檔案為.cpp檔

2)並選擇為Sample app type

開啟code blocks
開啟openGL專案

刪掉原本的main.c

在把新的cpp檔放進專案資料夾中

並將他開啟



註解掉那2個讀不了的程式碼

完成

匯出海豚:

依序將海豚匯出成obj檔(要記得選在Visible區域)

FB下載freeglut的檔案

還有老師有給myGLMsample檔案匯入codeblocks

將三隻海豚的檔案放進myGLMsample的data裡

更改檔案讀取部分程式碼就可以秀出模型

要同時做出第二個模型

請複製貼上並更改紅框區域再新增需要的程式碼

2隻完成

再做成3隻

隨意縮放旋轉
