Hi all,

I need to draw 2D graphic stuff (HUD) in top of a 3D stereo visual. I'm
using a Quadro 980XGL, and it appears to support hardware overlay planes.

I don't know if using overlay planes is better in terms of performance
than doing opengl calls in a postdraw callback. I will have to draw the
HUD once for each eye, and 2D information will be updated in every
frame. Does anybody know which is the best way to achieve this?

Thanks in advance for any help.
