week10
(1)
1-1.下載Opencv 2.1.0 win32 vs2008
1-2.CodeBlocks重開
1-3.File - New - Project ,開GLUT
1-4.複製上週程式
1-5.設定settings/Compiler
(1)Search diedctories
<1>Compiler
Add - C: \ OpenCV2.1 \ include
<2>Linker
Add - C: \ OpenCV2.1 \ lib
(2)Linker settings
Add - cv210 & cxcore210 & highgui210
1-6.檔案要放對地方!!
(2)
2-1.改程式(用begin&end)
#include <GL/glut.h>
#include <opencv/highgui.h>
#include <opencv/cv.h>
#include <GL/glut.h>
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 display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glBegin(GL_POLYGON);
glTexCoord2f(0,1);glVertex2f(-1,-1);
glTexCoord2f(1,1);glVertex2f(+1,-1);
glTexCoord2f(1,0);glVertex2f(+1,+1);
glTexCoord2f(0,0);glVertex2f(-1,+1);
glEnd();
glutSwapBuffers();
}
int main(int argc,char** argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("week10 texture background");
glutDisplayFunc(display);
myTexture("1.jpg");
glutMainLoop();
}
2-2.增加指標，把圖貼在球體上面
#include <GL/glut.h>
#include <opencv/highgui.h>
#include <opencv/cv.h>
#include <GL/glut.h>
GLUquadric * sphere =NULL;///指標，指到二次曲面
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 display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
gluQuadricTexture(sphere,1);
gluSphere(sphere,1,30,30);
glutSwapBuffers();
}
int main(int argc,char** argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("week10 texture background");
glutDisplayFunc(display);
myTexture("1.jpg");
sphere=gluNewQuadric();
glutMainLoop();
}
2-3.讓地球旋轉
#include <GL/glut.h>
#include <opencv/highgui.h>
#include <opencv/cv.h>
#include <GL/glut.h>
GLUquadric * sphere =NULL;///指標，指到二次曲面
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;
}
float angle=0;///旋轉角度
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glRotatef(angle,0,0,1);
gluQuadricTexture(sphere,1);///設貼圖
gluSphere(sphere,1,30,30);///畫圓球
glPopMatrix();
glutSwapBuffers();
angle+=1;///每次display()加1度
}
int main(int argc,char** argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("week10 texture background");
glutIdleFunc(display);///有空idle 呼叫display()
glutDisplayFunc(display);
myTexture("1.jpg");
sphere=gluNewQuadric();
glutMainLoop();
}
2-4.轉正地球
#include <GL/glut.h>
#include <opencv/highgui.h>
#include <opencv/cv.h>
#include <GL/glut.h>
GLUquadric * sphere =NULL;///指標，指到二次曲面

return id;
}
float angle=0;///旋轉角度
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glRotatef(90, 1,0,0);///轉正
glRotatef(angle, 0,0,1);
gluQuadricTexture(sphere,1);///設貼圖
gluSphere(sphere,1,30,30);///畫圓球
glPopMatrix();
glutSwapBuffers();
angle+=0.1;///每次display()加0.1度
}
int main(int argc,char** argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("week10 texture background");
glEnable(GL_DEPTH_TEST);///開3D測試
glutIdleFunc(display);///有空idle 呼叫display()
glutDisplayFunc(display);
myTexture("1.jpg");
sphere=gluNewQuadric();
glutMainLoop();
