cegui and stereo

[rickyviking]

Hi All,

simple question from a beginner...
In case I want to use a GUI in a stereo application, I should better render it on a regular polygon in the 3D world, rather than as an overlay.
This helps keeping the stereo coherence.

My questions are:
1) shoud I use render-to-texture technique (which I saw from previous posts it is possible) or there's another/better way to display cegui on a regular poligon?

2) in case the answer to point 1 is RTT only, how can I "emulate" the mouse event handling? meaning, if I create a 3D cursor (or "laser" beam or similar) and intersect the polygon I apply the RTT to, how can I understand on which feature I am (button, menu, etc...)

thanks a lot
Ricky
