主題:(1)Maya匯出obj模型(2)glm讀模型、畫(3)wav音效、mp3音樂(4)小遊戲(回家作業)

(1) 

用右鍵Notepad++開啟soccerball.obj

                                      soccerball.mtl

}

改變

pmodel = glmReadOBJ("data/porsche.obj"); ➡ pmodel = glmReadOBJ("data/soccerball.obj");

改變

pmodel = glmReadOBJ("data/porsche.obj"); ➡ pmodel = glmReadOBJ("data/al.obj");

在Lesson.cpp找sound

PlaySound("檔名.wav",NULL,SND_ASYNC)

(5)

1.#include <mmsystem.h>

2.void mouse(int button ,int state, int x, int y)

    {

        PlaySound("檔名.wav",NULL,SND_ASYNC)

    }

3.在main()裡面 glutCreateWindow()之後

 glutMouseFunc(Mouse);

        if (!pmodel) exit(0);

        glmUnitize(pmodel);

        glmFacetNormals(pmodel);

        glmVertexNormals(pmodel, 90.0);

    glPopMatrix();

    glutSwapBuffers();

}
