看了會吐的貼圖語法

#include <opencv/highgui.h>
#include <opencv/cv.h>
#include <GL/glut.h>
void display()
{
glEnable(GL_DEPTH_TEST);//深度測試
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glutSolidTeapot(0.3);
glutSwapBuffers();
}
int main()
{
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("01160581");
glutDisplayFunc(display);

//準備貼圖
glEnable(GL_TEXTURE_2D);
IplImage* img = cvLoadImage("earth.jpg");
cvCvtColor(img,img,CV_BGR2RGB);
GLuint id;
glGenTextures(1, &id);
glBindTexture(GL_TEXTURE_2D, id);
//以下貼圖檔在物件上
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_LINEAR);
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, img->width, img->height, 0,GL_RGB, GL_UNSIGNED_BYTE, img->imageData);

glutMainLoop();
// cvNamedWindow("week06");
// cvShowImage("week06",img);
// cvWaitKey(0);
}

有了這個，貼圖輕鬆打，看了不會吐！
