Hi,
It is basically a hardware, opengl related graphics question, but
I think the knowledge of these these things is much higher
in this group, which is the reason I post my question here.
We need to render in stereo to a 4 sided cubical projection system,
which means that every object in the scene in possibly drawn 8 times
(but culling is likely to reduce this number a bit).
The geometry itself is drawn using opengl (sorry no performer), but
changes its shape every frame.
Currently we put this shape into an array and use the array
extensions to draw the geometry.
The questions is about effeciency. Would it be better to use a display
list for such shapes and use COMPILE_AND_EXECUTE mode for filling them,
and then call the list possibly 7 more times? Are the displaylist shared
efficiently between the 4 pipesvia a separate, hopefully very fast, bus?
If there is such a connection, it might be a good idea, but is it???
best regards,
-frans
