Week17_魚筆記
複習之所做過的機器人相關程式碼，好讓我們可以成功完成會動的機器人
6.移3個檔案進自己的專案資料夾中
int main()
{
....
glutTimerFunc(1000,timer,0);
....
}
作業一
貼上背景圖
1.下載openCV 2.1版本並安裝
2.在my earth檔案中修改程式碼讓自己的圖片成功跑出
#include <opencv/highgui.h> ///for cvLoadImage()
#include <opencv/cv.h> ///for cvCvtColor()
#include <GL/glut.h> ///3D glut
#include <stdio.h>
GLUquadric * quad;
GLuint id;
float angle=0;
void display()
{ glEnable(GL_DEPTH_TEST); ///要啟動 Detph Test 深度值的測試,3D顯示才正確
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glPushMatrix();///自動轉很帥
glBegin(GL_POLYGON);
glTexCoord2f(0,0); glVertex3f(-1,+1,0);
glTexCoord2f(1,0); glVertex3f(+1,+1,0);
glTexCoord2f(1,1); glVertex3f(+1,-1,0);
glTexCoord2f(0,1); glVertex3f(-1,-1,0);
glPopMatrix();///自動轉很帥
glFlush();
}
void timer(int t)
{ glutTimerFunc(20, timer, 0);/// 1000 msec 50fps:20msec
angle+=1;///自動轉很帥
glutPostRedisplay();
}
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
glGenTextures(1, &id); /// 產生Generate 貼圖ID
glBindTexture(GL_TEXTURE_2D, id); ///綁定bind 貼圖ID
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); /// 貼圖參數, 超過包裝的範圖T, 就重覆貼圖
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); /// 貼圖參數, 超過包裝的範圖S, 就重覆貼圖
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST); /// 貼圖參數, 放大時的內插, 用最近點
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); /// 貼圖參數, 縮小時的內插, 用最近點
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, img->width, img->height, 0, GL_RGB, GL_UNSIGNED_BYTE, img->imageData);
return id;
}
void myInit()
{
quad = gluNewQuadric();
id = myTexture("we1.jpg");
}
int main(int argc, char**argv)
{ glutInit(&argc, argv);
glutCreateWindow("3D");
glutDisplayFunc(display); ///顯示
glutTimerFunc(0, timer, 0);
myInit(); ///我的 init 初始化 把貼圖準備好 前面OpenCV 2行, 後面 OpenGL 9行
glutMainLoop();
}
3.將my earth和自己機器人的專案檔(.cbp)用notepad++開啟，並複製my earth部分程式碼進去自己專案內

4.將my earth讀程式碼加進去自己專案中，成功跑出背景圖來
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
glGenTextures(1, &id); /// 產生Generate 貼圖ID
glBindTexture(GL_TEXTURE_2D, id); ///綁定bind 貼圖ID
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); /// 貼圖參數, 超過包裝的範圖T, 就重覆貼圖
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); /// 貼圖參數, 超過包裝的範圖S, 就重覆貼圖
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST); /// 貼圖參數, 放大時的內插, 用最近點
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); /// 貼圖參數, 縮小時的內插, 用最近點
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, img->width, img->height, 0, GL_RGB, GL_UNSIGNED_BYTE, img->imageData);
return id;
}
void myInit()
{
id = myTexture("we1.jpg");
}
void display()
{ glEnable(GL_DEPTH_TEST); ///要啟動 Detph Test 深度值的測試,3D顯示才正確
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glPushMatrix();///自動轉很帥
glBegin(GL_POLYGON);
glTexCoord2f(0,0); glVertex3f(-1,+1,0);
glTexCoord2f(1,0); glVertex3f(+1,+1,0);
glTexCoord2f(1,1); glVertex3f(+1,-1,0);
glTexCoord2f(0,1); glVertex3f(-1,-1,0);
glEnd();
glPopMatrix();///自動轉很帥
glFlush();
}
#include <opencv/highgui.h> ///for cvLoadImage()
#include <opencv/cv.h> ///for cvCvtColor()
#include <GL/glut.h> ///3D glut
GLuint id;
myInit(); ///我的 init 初始化 把貼圖準備好 前面OpenCV 2行, 後面 OpenGL 9行
5.打光，讓自己的模型不受圖檔點影響
glEnable(GL_TEXTURE_2D);///開2D貼圖
glDisable(GL_LIGHTING);///關掉打光
glDisable(GL_TEXTURE_2D);///關掉貼圖，才不因為最後貼圖點影響你的模型
glEnable(GL_LIGHTING);///打開打光
glEnable(GL_TEXTURE_2D);///開2D貼圖
glDisable(GL_LIGHTING);///關掉打光
glDisable(GL_TEXTURE_2D);///關掉貼圖，才不因為最後貼圖點影響你的模型
glEnable(GL_LIGHTING);///打開打光
6.移3個檔案進自己的專案資料夾中
作業二
使用Timer播放
接續自己專案檔的程式碼，新增計時器的函式
void timer(int t)
{
glutTimerFunc(100,timer,t+1);
{
glutTimerFunc(100,timer,t+1);
if(fin==NULL){
fin=fopen("file.txt","r"); //開啟檔案，檔名準備好，而且是用read模式
printf("Now open a file.txt for read Mode\n");
fscanf(fin,"%f %f %f %f %f %f %f %f %f %f",&newAngle[0],&newAngle[1],&newAngle[2],&newAngle[3],&newAngle[4],&newAngle[5],&newAngle[6],&newAngle[7],&newAngle[8],&newAngle[9]
);
}
if(alpha>=1.0){
for(int i=0;i<10;i++) oldAngle[i]=newAngle[i];
fscanf(fin,"%f %f %f %f %f %f %f %f %f %f",&newAngle[0],&newAngle[1],&newAngle[2],&newAngle[3],&newAngle[4],&newAngle[5],&newAngle[6],&newAngle[7],&newAngle[8],&newAngle[9]
);
printf("Now read angle[]\n");
alpha=0.0;
}
for(int i=0;i<10;i++){
angle[i]=alpha*newAngle[i]+(1-alpha)*oldAngle[i];
}
alpha+=0.1;
glutPostRedisplay();
}int main()
{
....
glutTimerFunc(1000,timer,0);
....
}

if(key=='s' || key=='S')
{
if(fout==NULL)
{
fout=fopen("file.txt","w+");
printf("現在我產生一個file.txt的檔案在目錄裡面哦\n");
}
fprintf(fout, "%.3f %.3f %.3f %.3f %.3f %.3f %.3f %.3f\n", angle[0],angle[1],angle[2],angle[3],angle[4],angle[5],angle[6],angle[7]);///寫檔案的第5行
printf("現在我把一些數字印到檔案裡面%.3f %.3f %.3f %.3f %.3f %.3f %.3f %.3f\n",angle[0],angle[1],angle[2],angle[3],angle[4],angle[5],angle[6],angle[7]);
}
if(key=='r' || key=='R')

T-R-T觀念小考講解
移動手臂或小腿之中心點在旋轉其角度移至特定座標
glPushMatrix();
glTranslatef(0.4,-1.0,0); ///4.再把樓下對旋轉的腿移至(0.4,-1.0,0)

glTranslatef(0.2,-0.5,0); ///2.把旋轉中心點放在畫面中間
drawLeg(); ///1.畫一個小腿
glPopMatrix();
P.S移動角度的正負為 : 順時針為負,逆時針為正
作業二
1.先下載openCV2.1並安裝
其他的不用變
2.可在C槽中找到openCV的資料夾，其中必備3大重要bin、include、lib
3.開啟CodeBlocks新增貝殼專案(C++ 副檔名為.cpp)
4.先畫一個圖存成png檔再C槽
5.讀圖檔的程式撰寫
#include <opencv/highgui.h>
int main()
{
IplImage * img = cvLoadImage("C:/star.png");
cvShowImage("a",img);
cvWaitKey(0);
}
執行時會有錯誤 因為還沒讀入opencv
6.讀入opencv使檔案可以執行
7.成功教出圖檔
作業三
轉動的地球
1.myEarth.zip解壓縮到桌面
2.freeglut.zip解壓縮到桌面
3.開啟myEarth專案檔

glut32.dll(解壓縮到桌面\移到window資料夾裡\glut32.dll)
source.zip(解壓縮到桌面\移到window資料夾裡\source)
3.開啟Projection
4.試著調整gluLookAt(eyeX,eyeY,eyeZ, ///攝影機
centerX,centerY,centerZ,
upX,upY,upZ)
作業二
矩陣 投影矩陣
攝影機運鏡
1.開啟04160011_hw1_project.zip 成功執行後如圖下
#include <GL/glut.h>
float eyeX=0, eyeY=0, eyeZ=1;
float centerX=0, centerY=0, centerZ=0;
float upX=0, upY=1, upZ=0;
static void display(void)
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3d(1,0,0);
glPushMatrix();
gluLookAt(eyeX, eyeY, eyeZ,
centerX, centerY, centerZ,
upX, upY, upZ);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
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 };
/* Program entry point */
int main(int argc, char *argv[])
{
glutInit(&argc, argv);
glutInitWindowSize(640,480);
glutInitWindowPosition(10,10);
glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("GLUT Shapes");
///glutReshapeFunc(resize);

glClearColor(1,1,1,1);
///glEnable(GL_CULL_FACE);

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();
return EXIT_SUCCESS;
}
2.修改gluLookAt(eyeX,eyeY,eyeZ 看看茶壺的變化(更改紅色部分的數值)
#include <GL/glut.h>
float eyeX=0, eyeY=0, eyeZ=0.6;
float centerX=0, centerY=0.5, centerZ=0;
float upX=0, upY=1, upZ=0;
static void display(void)
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3d(1,0,0);
glPushMatrix();
gluLookAt(eyeX, eyeY, eyeZ,
centerX, centerY, centerZ,
upX, upY, upZ);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
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 };
/* Program entry point */
int main(int argc, char *argv[])
{
glutInit(&argc, argv);
glutInitWindowSize(640,480);
glutInitWindowPosition(10,10);
glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("GLUT Shapes");
///glutReshapeFunc(resize);
glutDisplayFunc(display);
///glutKeyboardFunc(key);
///glutIdleFunc(idle);
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);

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();
return EXIT_SUCCESS;
}
3.改gluPerspective(fov , 1, near, far) ///fov為視野角, 1為xy比例
不讓茶壺旋轉時破碎
#include <GL/glut.h>
#include <math.h>
float eyeX=1, eyeY= 0, eyeZ= 0;
float centerX=0, centerY=0, centerZ=0;
float upX=0, upY=1, upZ=0;
float angle=0;
static void display(void)
{
glMatrixMode(GL_PROJECTION);
glLoadIdentity(); ///備份矩陣
gluPerspective(60, 1, 0.001, 10000); ///讓茶壺不會因為旋轉而破碎 透視矩陣
glMatrixMode(GL_MODELVIEW);
angle+=0.01;
eyeX=cos(angle); eyeZ=sin(angle);
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3d(1,0,0);
glPushMatrix();
gluLookAt(eyeX, eyeY, eyeZ,
centerX, centerY, centerZ,
upX, upY, upZ);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
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 };
/* Program entry point */
int main(int argc, char *argv[])
{
glutInit(&argc, argv);
glutInitWindowSize(640,480);
glutInitWindowPosition(10,10);
glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("GLUT Shapes");

glMaterialfv(GL_FRONT, GL_SPECULAR, mat_specular);
glMaterialfv(GL_FRONT, GL_SHININESS, high_shininess);
glutMainLoop();
return EXIT_SUCCESS;
}
