睏

 

==================================

• 先下載這些檔案

解壓縮:

windows.zip => 下載 \ windows \ Transformation.exe

data.zip         => 下載 \ windows \ data \ 模型

• 把一些檔案丟進桌面的專案檔
• glm.c 改成 glm.cpp
• transformation  的程式碼複製取代專案裡 main.cpp 的程式碼

• 把 glm.cpp add file 進專案裡

• 把 data.zip 裡的 data資料夾丟進  freegult \ bin

• 完成就可以運作了

=================================================

• 剛剛程式碼中的車子

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);

    drawmodel();

    glutSwapBuffers();

}

int main(int argc, char **argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("08160830 week11");

    glutDisplayFunc(display);

    glutMainLoop();

}

• 加上打光的程式碼和轉180度
• 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();

}
