##week06-1_lighting

1.File-New-Project,GLUT專案

2.貼上11行GLUT程式

3.20行程式拿來用

4.畫出立體茶壺

##看課本範例

jsyeh.org/3dcg10 下載 source windows data，開啟Light Material.exe

##week06-2_lighting_glNormal3f

1.新專案

2.貼上week06-1

3.把茶壺變正方形

4.加上mouse轉動正方形

##week06-3_glm_obj_model

1.File-New-Project, GLUT專案, week06-3_glm_obj_model

2.把11行程式GLUT,先做出來

3.參考 source.zip 裡面的transformation.c

3.1. #include "glm.h"

3.2. GLMmodel*pmodel=NULL;

3.3.讀模型、畫模型 void drawmodel(void)這個函式

4.將檔案準備好:

4.1. glm.h放到week06-3_glm_obj_model目錄裡

4.2.改檔名glm.cpp

4.3.專案,按右鍵,新增檔案,將glm.cpp加入專案

4.4.將data資料夾,複製到 桌面\freeglut\bin執行目錄裡

4.5.把glutSolidTeapot(0.3);換成drawmodel();
