Hi.
You need to do a little more work than this.
int loadTexture_Ipl(IplImage *image, GLuint *text) {
if (image==NULL) return -1;
glGenTextures(1, text);
glBindTexture( GL_TEXTURE_2D, *text ); //bind the texture to it's array
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR);
glPixelStorei(GL_UNPACK_ALIGNMENT, 1);
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, image->width, image->height,0, GL_BGR, GL_UNSIGNED_BYTE, image->imageData);
return 0;
}
Clearly you are using a cv::Mat but i think you can use cv::Mat.data in place of image->imageData.

return 0;
}
The above is pretty old school. Are there no examples?
