#week09-0_sample
1.安裝 freeglut, lib\libfreeglut.lib 複製成 libglut32.a
2.新增glut專案 week09-0_sample
##程式碼重新再利用
1.下載上週程式碼 安裝github
-在小黑裡指令:
-cd desktop
-git clone https://github.com/你的帳號/2024graphicsb
-cd 2024graphicsb
-start
2.確認環境沒問題
- 安裝openCV 要勾add path, 裝載預設目錄
-setting-compiler裡 把openCV三個設定好
-上方第三個分頁 Search directories 裡
- Compiler TH C: \OpenCv2.1\include - Linker JI C: \OpenCV2.1 Lib
-上方第二個分頁 Linker Setting - cv210 cxcore210 highgui210 24
-重新開啟 CodeBlocks
3.專案設定修改(seting-compiler...)
##開啟上週專案week07-2_obj_gundam_opencv_texture
1.file open, 點選剛剛下載的git 下載的 week07-2_obj_gundam_opencv_texture
-C:\User\adminidtrator\Desktop\2024grapgicsb\week07-2_obj_gundam_opencv_texture
##week09-1_obj_gundam_opencv_texture_lighting
-上週程式專案拿出來
-week07-2目錄打開 更改檔名 cbp檔
-打光的8行陣列 貼在程式上
-打光12+2行函式 貼到glutMaunLoop()
-glmDraw(pmodel, GLM_SMOOTH| GLM_TEXTURE) 刪掉中間
-打光 加入旋轉
