DannyLo筆記 Week06

本周主題:匯入模型

1.去http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/下載data,win32,glut32.dll,source

2.把source中 glm.c , glm.h丟到建立的project資料夾中,並把glm.c改成glm.cpp

3.把data放到freeglut中的bin資料夾中(因為程式是從bin中讀取模型的)

4.把glm.cpp用add files加入到project中


5.打開source資料夾中的lightmaterial.c 用ctrl+f找glm 並把其中的程式碼 加入到上周的程式碼(main.cpp)

(放到#include之下)
#include "glm.h"
GLMmodel* pmodel = NULL;
(放到display之中)
if (!pmodel) {
pmodel = glmReadOBJ("data/soccerball.obj");
if (!pmodel) exit(0);
glmUnitize(pmodel);
glmFacetNormals(pmodel);
glmVertexNormals(pmodel, 90.0);

    }

include .h檔 外掛
link lib 連結程式用
bin .dll檔 執行

V:VERTEX 頂點
VN:VERTEX NORMAL 法向量

6.最後程式碼
#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); if (!pmodel) { pmodel = glmReadOBJ("data/soccerball.obj"); if (!pmodel) exit(0); glmUnitize(pmodel); glmFacetNormals(pmodel); glmVertexNormals(pmodel, 90.0); } glmDraw(pmodel, GLM_SMOOTH); glutSwapBuffers(); } int main(int argc,char**argv) { glutInit(&argc,argv); glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH); glutCreateWindow("week05"); glutDisplayFunc(display); 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(); }

匯出模型
要先點選要匯出的模型

之後如果要用程式輸出模型，先把這兩個匯出的東西放到freeglut的bin之中

然後更改程式碼
#include <GL/glut.h> #include "glm.h" GLMmodel* pmodel = NULL; float x=0,y=0; 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); glPushMatrix(); glRotatef(y,1,0,0); //是讀取滑鼠當前位置 所以放開點下去都會重新讀取一次 glRotatef(x,0,1,0); if (!pmodel) { pmodel = glmReadOBJ("rere.obj"); ///更改成要顯示的檔
如果放在data中 前面加data/
if (!pmodel) exit(0); glmUnitize(pmodel); glmFacetNormals(pmodel); glmVertexNormals(pmodel, 90.0); } glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL); glPopMatrix(); glutSwapBuffers(); } void motion(int nowx,int nowy) { x=nowx;y=nowy; display(); } int main(int argc,char**argv) { glutInit(&argc,argv); glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH); glutCreateWindow("week05"); glutDisplayFunc(display); glutMotionFunc(motion); 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(); }

●如何壤程式碼變彩色●

1.把程式碼複製到notepad++，另存新檔成 .cpp 檔
2.Export成html檔
 

3.用Google打開

4.再一次複製程式碼
