【03160135_吳亞芳】Week12

課堂一

• 前往老師的網站下載教材：jsyeh.org/3dcg10

下載 glut32.dll、[data][win32][source]四個檔案

windows解壓縮裡面exe檔放到2016CG資料夾




















data壓縮檔裡整個data資料夾(包含obj.mtl檔)放到2016CG資料夾



















glut32.dll也移進

-
開新空白(貝殼)專案

source裡的glm.c、transformation.c、glm.h放進專案資料夾

原本的main.c刪掉

調換成transformation.c、glm.c

解壓縮freeglut在桌面

加咒語、路徑

專案按右鍵

選Build option...

在Searth directories標籤下的
Compiler標籤加入在freeglut資料夾裡面的include資料夾路徑

Linker標簽下加入在freeglut資料夾裡面的lib資料夾路徑

Linker Setting裡加入咒語(有順序)

freeglut

opengl32

gul32

gdi32

winmm

專案資料夾需要freeglut/bin裡的freeglut.dll

專案資料夾裡需要data資料夾

執行

*-

transformation.c改名->myOBJ.cpp
glm.c改名->glm.cpp

rebuild後執行

/*課堂四


main裡加
    glLightfv(GL_LIGHT0, GL_POSITION, pos);
    glEnable(GL_LIGHT0);
    glEnable(GL_LIGHTING);
    glEnable(GL_DEPTH_TEST);

打光的程式碼


glRotatef(90, 0,1,0); //看車頭


GLfloat pos[] = {0.0, 0.0, -1.0, 0.0};// 打光從前面打
