懶嵐\(。∀ ° )/ Week11

 Part1.

到Moodle的上課用軟體下載

windows.zip , source.zip , data.zip

然後解壓縮

把source資料夾裡的glm.c , glm.h , transformation.c

複製到glut專案資料夾裡

glm.c直接改成glm.cpp

transformation.c用notepad++打開

複製貼到專案的main.cpp

把glm.cpp加進專案

把data.zip資料夾裡的檔案放進freeglut資料夾的bin

就可以解決閃退的問題了

Part2.

程式碼全部刪掉

換成

#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);///清空

    drawmodel();///glutSolidTeapot(0.3)

    glutSwapBuffers();

}

int main(int argc, char *argv[])///main()函式

{

    glutInit(&argc, argv);///(1)Init初始化GLUT

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);///(2)Init初始化 Display 的功能

    glutCreateWindow("Week11 3D模型");///(3)建立GLUT視窗

    glutDisplayFunc(display);///(4)準備display()函式

    glutMainLoop();///(5)主要程式

}

得到一個白色的東東

Part3.

加上前幾個禮拜教的打光

#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);///清空

    glPushMatrix();

        glRotatef(180,0,1,0);

        drawmodel();

    glPopMatrix();

    glutSwapBuffers();

}
