 Step01-1

從github下載並開啟舊專案Final_Project

相對路徑改成絕對路徑

把freeglut整個資料夾複製到專案內

Step01-2

開啟.gitignore用notepad++修改內部程式，註解掉*.a *.lib並儲存

Step02-1

把glm.h和glm.cpp加入到專案內

程式碼

#include <stdio.h>

#include <GL/glut.h>

#include "glm.h"

GLMmodel * body  =NULL;

        glmUnitize(head);

    glmDraw(head,GLM_MATERIAL);
