謝謝小_week06

今日課程內容

嗚嗚嗚嗚嗚

1.使用老師提供的網站(http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/)

1.先下載win32, data, glut32.dll,source 2.將win32, data解壓縮後將所有資料放入windows資料夾

2.開起每周慣例的茶壺

1.按照老方法開啟glut

2.使用上周打光的茶壺

#include <GL/glut.h>

float x=0,y=0;

float angle=0;//開始角度

 const GLfloat light_ambient[]  = { 0.0f, 0.0f, 0.0f, 1.0f };

    const GLfloat light_diffuse[]  = { 1.0f, 1.0f, 1.0f, 1.0f };

    const GLfloat light_specular[] = { 1.0f, 1.0f, 1.0f, 1.0f };

    const GLfloat light_position[] = { 2.0f, 5.0f, 5.0f, 0.0f };

    const GLfloat mat_ambient[]    = { 0.7f, 0.7f, 0.7f, 1.0f };

    const GLfloat mat_diffuse[]    = { 0.8f, 0.8f, 0.8f, 1.0f };

    const GLfloat mat_specular[]   = { 1.0f, 1.0f, 1.0f, 1.0f };

    const GLfloat high_shininess[] = { 100.0f };

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);//滑鼠移動

    glPushMatrix();

    glRotatef(angle,0,1,0);//以角度決定旋轉

    glColor3f(0.8,0.6,0);

    glutSolidTeapot(0.3);

    glPopMatrix();

    angle++;//角度++，可調整角度以增加速度

    glutSwapBuffers();

}

void motion(int nowx,int nowy)

{

    x=nowx; y=nowy;//滑鼠移動

    display();

}

int main(int argc,char ** argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week05 translate 06160095");

    glutDisplayFunc(display);

    glutIdleFunc(display);//需要，否則不會自動旋轉

        glClearColor(1,1,1,1);

    glEnable(GL_CULL_FACE);

    glCullFace(GL_BACK);

    glEnable(GL_DEPTH_TEST);

    glDepthFunc(GL_LESS);

    glEnable(GL_LIGHT0);

    glEnable(GL_NORMALIZE);

    glEnable(GL_COLOR_MATERIAL);

    glEnable(GL_LIGHTING);

        glLightfv(GL_LIGHT0, GL_AMBIENT,  light_ambient);

    glLightfv(GL_LIGHT0, GL_DIFFUSE,  light_diffuse);

    glLightfv(GL_LIGHT0, GL_SPECULAR, light_specular);

    glLightfv(GL_LIGHT0, GL_POSITION, light_position);

    glMaterialfv(GL_FRONT, GL_AMBIENT,   mat_ambient);

    glMaterialfv(GL_FRONT, GL_DIFFUSE,   mat_diffuse);

    glMaterialfv(GL_FRONT, GL_SPECULAR,  mat_specular);

    glMaterialfv(GL_FRONT, GL_SHININESS, high_shininess);

    glutMotionFunc(motion);//執行

    glutMainLoop();

}

2.更改程式碼

將lightmaterial.c的檔案用Notepad++開啟並搜尋"glm"來更改程式碼

3.程式碼:

#include <GL/glut.h>

#include "glm.h"

GLMmodel* pmodel = NULL;

 const GLfloat light_ambient[]  = { 0.0f, 0.0f, 0.0f, 1.0f };

    const GLfloat light_diffuse[]  = { 1.0f, 1.0f, 1.0f, 1.0f };

    const GLfloat light_specular[] = { 1.0f, 1.0f, 1.0f, 1.0f };

    const GLfloat light_position[] = { 2.0f, 5.0f, 5.0f, 0.0f };

    const GLfloat mat_ambient[]    = { 0.7f, 0.7f, 0.7f, 1.0f };

    const GLfloat mat_diffuse[]    = { 0.8f, 0.8f, 0.8f, 1.0f };

    const GLfloat mat_specular[]   = { 1.0f, 1.0f, 1.0f, 1.0f };

    const GLfloat high_shininess[] = { 100.0f };

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);//滑鼠移動

    if (!pmodel) {

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

if (!pmodel) exit(0);

glmUnitize(pmodel);

glmFacetNormals(pmodel);

glmVertexNormals(pmodel, 90.0);

    }

    glmDraw(pmodel, GLM_SMOOTH|GLM_MATERIAL);

    glutSwapBuffers();

}

int main(int argc,char ** argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("隱睪勝");

    glutDisplayFunc(display);

    glutIdleFunc(display);//需要，否則不會自動旋轉

        glClearColor(1,1,1,1);

    glEnable(GL_CULL_FACE);

    glCullFace(GL_BACK);

    glEnable(GL_DEPTH_TEST);

    glDepthFunc(GL_LESS);

    glEnable(GL_LIGHT0);

    glEnable(GL_NORMALIZE);

    glEnable(GL_COLOR_MATERIAL);

    glEnable(GL_LIGHTING);

        glLightfv(GL_LIGHT0, GL_AMBIENT,  light_ambient);

    glLightfv(GL_LIGHT0, GL_DIFFUSE,  light_diffuse);

    glLightfv(GL_LIGHT0, GL_SPECULAR, light_specular);

    glLightfv(GL_LIGHT0, GL_POSITION, light_position);

    glMaterialfv(GL_FRONT, GL_AMBIENT,   mat_ambient);

    glMaterialfv(GL_FRONT, GL_DIFFUSE,   mat_diffuse);

    glMaterialfv(GL_FRONT, GL_SPECULAR,  mat_specular);

    glMaterialfv(GL_FRONT, GL_SHININESS, high_shininess);

    glutMainLoop();

}

4.開啟時會遇到三個問題

1.找不到glm檔

解決辦法:

將"source"壓縮檔裡的"glm.h"檔案丟到跟mian.cpp同位置的資料夾

2.找不到模組

解決辦法:將"source"壓縮檔裡的"glm.c"檔案丟到跟mian.cpp同位置的資料夾並更改名稱為"glm.cpp"

之後點選右方"week06"然後"add files"點選"glm.cpp"

3.視窗閃退

解決辦法:將"data"壓縮檔裡的"data"檔加到"freeglut"的"bin"裡面

終於可以執行了~~~~~

5.如何讓程式碼變彩色

1.將所有程式碼全選貼到notepad++
2.存成.cpp檔
3.安裝外掛 ⇒ NppexPort ⇒ Export to HTML ⇒ 用google開啟
4.再將程式碼複製貼上
