Hi, here's a very special case of Qt integration for OpenSceneGraph for which I am searching for a solution: We're using Qt to draw into a QPixmap (updating a map of measured radio conditions during a simulation in realtime). We optionally support a 3D display, which is typically a line by line polarized display. Simply opening a Qt window displaying the pixmap produces bad artifacting. When we open a window on the 3D display (on top of the OSG rendered output), it gets torn because every second line is visible only to each eye.
So the only chance to display it right, would be to render the map as a HUD in OpenScenegraph so it gets rendered through the stencil buffer so it shows up nicely for both eyes. Now here's the question: How to transfer the contents of the QPixmap into a texture for OpenSceneGraph efficiently? A lot of texture updates using the CPU would likely slow down the entire application - if possible we would like to avoid slow updates and take a faster route. But which one could that be?
