1.Maya匯出OBJ模型

先到這 http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/

下載: source.zip  & windows.zip & data.zip & glut32.dll

右鍵使用Notepad++開啟 soccerball.obj & soccerball.mtl

2.glm讀模型.畫

先解壓縮 myGLMsample.zip 
然後要把 freeglut 放在桌面才能執行

        if (!pmodel) {
        pmodel = glmReadOBJ("data/soccerball.obj");

        glmUnitize(pmodel);
        glmFacetNormals(pmodel);
        glmVertexNormals(pmodel, 90.0);
        }

        glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);
