week11 上課遲到

1.將老師要求的source 、 windows 、data資料夾解壓縮，將source裏頭的glm.c改成glm.cpp。

2.老樣子的開啟glut專案，將glut專案加入

3.將glm.cpp和glm.h移至glut專案
資料夾

4.codeblocks add file glm.cpp

5.將剛才解壓縮的data資料夾丟入freeglut的bin資料夾中。

尚未打光的保時捷

(程式碼如下)

#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");

    glutDisplayFunc(display);

    glutMainLoop();

}

幫保時捷打光

(程式碼如下)

#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();

}
