Source檔案裡面的glm.h放到專案資料夾glm.c也放進去但要改成cpp

transformation.c複製程式碼內容放到main.cpp裡面

再把glm.c一起匯入到codeblocks裡面

把data資料夾裡面的data資料夾放入freeglut資料夾的bin裡面執行就可以成功

去transfomation找到glm相關的程式碼複製下來

#include "glm.h"//使用glm.cpp的外掛

GLMmodel*pmodel=NULL;//pmodel指標

void drawmodel(void)//使用範例的程式

{

    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();//使用範例的程式

    glutSwapBuffers();

}

int main(int argc,char ** argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week11");

    glutDisplayFunc(display);

    glutMainLoop();

}

就可以把保時捷畫出來

把上次打光的程式碼抓下來

#include "glm.h"//使用glm.cpp的外掛

GLMmodel*pmodel=NULL;//pmodel指標

void drawmodel(void)//使用範例的程式

{

    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();//使用範例的程式

    glPopMatrix();

    glutSwapBuffers();

}
