Dear Ioana,
There's no obvious answer yet, since I haven't even had a chance
to see one of these new Sharp laptops yet. They sound similar in
design to the DTI autostereoscopic flat panel displays that VMD
already has support for, but I haven't been able to track down
any specific details on how their display works with OpenGL.
If its a display built with a parallax barrier, then most likely
VMD would achieve stereo by one of two means:
A) standard OpenGL stereo functionality
(dubious, most of the other autostereo displays
require weird rendering hacks presently...)
B) stencil buffer based rendering tricks where VMD skips rendering
every other horizontal or vertical line and then merges the left
and right images into a single buffer. Even in the case of A), this
would be done by their display driver.
Since Sharp has no information on their web site yet (at least
that I was able to find) I can't really hazard a guess as to which
situation it is.
In any case, if you want an autostereoscopic display for an SGI, you
can use one of the DTI flat panel displays with VMD, I tested one here
a number of months back, on PCs, Suns, etc, and it worked fine.
I hope this is at least somewhat helpful for you. My advice would
be to test the software (including VMD) you want to run on a demo
laptop before you plunk down the cash.
Thanks,
John Stone
