1.
從網站 http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/
下載data、win32、glut32.dll 三檔案
將win32解壓縮然後把glut32.dll 放入window資料夾
data解壓縮後拉進win32資料夾

開啟light material

上格按右鍵可更換模型

下格按右鍵可更換顏色

GL_float light_pos[ ]={ x,y,z,1};
可以調整光的位置 ， 前三個位置分別對應 x y z

2.
網址下載freeglut
https://www.transmissionzero.co.uk/software/freeglut-devel/

選擇freeglut 3.0.0 MinGW Package

freeglut解壓縮至桌面
lib中複製一個libfreeglut.a
並改名為libglut32.a
開啟codeblocks

程式碼 #include <GL/glut.h>

const GLfloat light_diffuse[]  = { 1.0f, 1.0f, 1.0f, 1.0f };
const GLfloat light_specular[] = { 1.0f, 1.0f, 1.0f, 1.0f };

const GLfloat high_shininess[] = { 100.0f };
