*glm_obj_model

step1GLUT專案 命名 week06-3_glm_obj_model

step2把11行程式GLUT貼上

step3.參考 source.zip 裡面的transformation.c (jsyeh....的網頁內

step3-1. 新增 #include "glm.h"

step3-2. GLMmodel*pmodel=NULL;

step3-3.製作模型函式- void drawmodel

(void)

step4. glm.h放到week06-3_glm_obj_model目錄裡

step4-1.改檔名glm.cpp

step4-3.右鍵新增檔案 add "glm.cpp"

step4-4.將data資料夾,複製到 桌面"freeglut bin"執行目錄裡

step4-5.glutSolidTeapot->drawmodel();
