電腦圖學 week11

1. Moodle下載範例 source.zip windows.zip, data.zip

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

data.zip =解壓縮=> 下載\windows\data\模型

2. File-New-Project, GLUT專案 (設好 freeglut)

從source.zip 複製glm.c glm.h transformation.c到week11.1資料夾裡

2. source.zip 裡的檔案加進去...

glm.h 放同目錄 (桌面的week11_model專案目錄)

glm.c 改檔名成 glm.cpp

在data.zip拉出data到freeglut\bin

2.把 glm.cpp 放入專案

左邊Project裡, Add檔案, glm.cpp加入

開啟glm.cpp

2.複製transformation的程式到codeblock會跑出上圖

transformation.c 內容放到 main.cpp

#include "glm.h"

GLMmodel* pmodel = NULL;

void drawmodel(void)

{

if (!pmodel) {

pmodel = glmReadOBJ("data/Al.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();///glutSolidCube(0.3);

glutSwapBuffers();

}

int main(int argc, char ** argv)

{

glutInit( &argc, argv );

glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH );

glutCreateWindow("08163034!!!");

glutDisplayFunc(display);

glutMainLoop();

}

5.加入打光組合!

!!下星期做!!

6. 整合貼圖用 Week08的貼圖函式

6.1. myTexture()

6.2. 在 main() 的 glutMainLoop()之前 myTexture("Diffuse.jpg")

6.3. 安裝 OpenCV 2.1, 小心 PATH

6.4. CodeBlocks 的 Setting-Compiler要設好多東西

C:\OpenCV2.1\include

C:\OpenCV2.1\lib

cv210 cxcore210 highgui210

再重開 CodeBlocks即可!!!!

///全刪,再copy的啦

#include <opencv/highgui.h> ///使用 OpenCV 2.1 比較簡單, 只要用 High GUI 即可

#include <opencv/cv.h>

#include <GL/glut.h>

GLuint id1, id2; ///TODO:增加2個貼圖ID

int myTexture(char * filename)

{

IplImage * img = cvLoadImage(filename); ///OpenCV讀圖

cvCvtColor(img,img, CV_BGR2RGB); ///OpenCV轉色彩 (需要cv.h)

glEnable(GL_TEXTURE_2D); ///1. 開啟貼圖功能

GLuint id; ///準備一個 unsigned int 整數, 叫貼圖ID

7. 老師傳的 gundam.zip 檔, 對應 gundam 目錄

7.1. 用 CodeBlocks 開啟 gundam.cbp 專案檔

7.2. 只要 OpenCV有裝好, 就可以有彩色的 gundam出來

2021年5月5日星期三

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

}

小乖的圖學筆記 week11

1. Moodle下載範例 source.zip windows.zip, data.zip

windows.zip 解壓縮至下載\windows\Transformation.exe

data.zip 解壓縮至下載\windows\data\模型

2.打開GLUT專案(自己去week01看)

3.將glm.h和glm.c放同目錄 (week11-1專案目錄)

glm.c 改檔名成 glm.cpp

transformation.c 內容放到 main.cpp

4.把 glm.cpp 放入專案(左邊Project>Add檔案>glm.cpp加入)

5.把 data.zip 裡的檔案放入執行目錄

C:\Users\Administrator\Desktop\freeglut\bin

6.程式碼執行如下

7.將main.cpp裡的程式碼刪掉至剩下

drawmodel(void)
{
if (!pmodel) {
pmodel = glmReadOBJ("data/Al.obj");
if (!pmodel) exit(0);
glmUnitize(pmodel);
glmFacetNormals(pmodel);
glmVertexNormals(pmodel, 90.0);
}
glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);
}

並且從GitHub裡下載並複製

void display()以及int main()

修改成以下

#include <GL/glut.h>
#include "glm.h"
GLMmodel * pmodel=NULL;
drawmodel(void)
{
if (!pmodel) {
pmodel = glmReadOBJ("data/Al.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();
}
int main(int argc,char ** argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE|GL_DEPTH_BUFFER_BIT);
glutCreateWindow("¤p¨Äªº3D¼Ò«¬");
glutDisplayFunc(display);
glutMainLoop();
}

8.程式碼執行如下

9.加入打光程式碼兩段並翻轉模型

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 };

加在void display()以及int main()之間

glEnable(GL_DEPTH_TEST);
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);

加在int main()裡的glutDisplayFunc(display);以及glutCreateWindow(" ");之間

void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glRotatef(180,0,1,0);
drawmodel();
glPopMatrix();
glutSwapBuffers();
}

加上這段已翻轉模型

10.程式碼執行如下

11.安裝OpenCV並重開(教學在week08)

12.開啟老師給的gundam中的cbp檔並執行

築損 Week11

第1部份

Moodle下載 windows.zip data.zip source.zip

解壓縮到資料夾

把 windows/glm.c&glm.h&transformation.c複製到glut專案資料夾中

glm.c改成 glm.cpp

tansformation.c用notepad++打開複製

貼到專案中 main.cpp

將 glm.cpp加入專案中

把data.zip中的檔案放到freeglut/bin

就能解決閃退問題

全部刪掉換成

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);///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
}

就有圖形了

加上旋轉圖
