[Fluxus] Side by Side Stereoscopy

[Ted]

Hi the list,
still working on Fluxus and a passive 3D stereoscopik system.
A step closer, we just received our circular polarisation filters for
the two video-projectors.
I watched the scrathpad.ss as you recommended but I'm not very
confortable with all renderer functions.
My goal is to make an automatic resising two side-by-by "viewports".
Many questions come.
Is (fluxus-reshape-callback x y) the best way to resize the Fluxus
window?
What mean all these important-seems functions?
    (draw-buffer *)
    (do-render)
    (clear-frame *)

When I'm trying a basic
      ((eq? stereo-mode 'sidebyside)
        (fluxus-reshape-callback (* width 2) height)
        (do-render)
      )
line 216 in modules/scheme/scratchpad.ss, I'm getting a #f return from
(set-stereo-mode 'sidebyside)

If someone can help me on this...
Thanks in advance.

Cheers,
Ted
