諺哥的圖學筆記 week02

week02

 1. 下載範例 https://jsyeh.org/3dcg10

   data.zip windows.zip glut32.dll

2. windows.zip =解壓=> 下載\windows\Shapes.exe

   data.zip =解壓=> 下載\windows\data\模型

   glut32.dll =複製=> 下載\windows\glut32.dll

3. 跑 Shapes.exe 看範例, 試試看

   左可按右鍵選單: 大頂點、很多顏色

   右可按右鍵選單: POINT....POLYGON 

1. 上週的安裝 Git for Windows

2. 上週的 Git Bash: cd desktop, git clone 你的網址 cd 2022graphics

3. 上週的安裝 freeglut, 記得改檔名 lib\libglut32.a

4. 在 CodeBlocks File-Open week01_GLUT專案,跑!
