glm.c改名成glm.cpp

transformation.c的程式碼取代codeblock的main.cpp

加入glm.cpp到專案裡

 #include "glm.h"

GLMmodel* pmodel = NULL;

void drawmodel(void)

{

    if (!pmodel) {

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

if (!pmodel) exit(0);

glmUnitize(pmodel);

glmFacetNormals(pmodel);

glmVertexNormals(pmodel, 90.0);

    }

    glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);

}

void display()

{

    glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    drawmodel();

    glutSwapBuffers();

}

int main(int argc, char** argv)

{

    glutInit( &argc, argv);

    glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH );

    glutCreateWindow("Week11 我的3D模型");

    glutDisplayFunc(display);

    glutMainLoop();

}

幫圖案加打光

程式碼:

#include "glm.h"

GLMmodel *pmodel = NULL;

void

drawmodel(void)

{

    if (!pmodel) {

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

if (!pmodel) exit(0);

glmUnitize(pmodel);

glmFacetNormals(pmodel);

glmVertexNormals(pmodel, 90.0);

    }

    glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glRotatef(180,0,1,0);

        drawmodel();

    glPopMatrix();

    glutSwapBuffers();

}
