title: Cannot see IplImage in QGraphicsView
body: <p>I'm trying to display a 3D scene(OpenGL-OpenCV) in a QGraphicsView object in QT. The scene has 5 planes: top, bottom, right, left and front. I'm taking images from my webcam and mapping them to the front plane. I have successfully displayed 4 of 5 planes, the front plane is missing.    </p>
  
  <p>I followed this tutorial to load the OpenGL scene: <a href="http://doc.trolltech.com/qq/qq26-openglcanvas.html" rel="nofollow">http://doc.trolltech.com/qq/qq26-openglcanvas.html</a>   </p>
  
  <p>However, I don't know how to treat the IplImage to be displayed in the QT Object. Do you guys have any suggestion?   </p>
