When the credits roll, be sure to cheer for Adam Shand, former
Portlander, co-founder of the Personal Telco Project, and now
head sysadmin for WETA Digital in N.Z.


Locally, Boyd MacNaughton licenses designs for "NuVision" 3D glasses,
which work with regular monitors and fast frame rates (frame-shutter
3D).  The glasses for Avatar are passive circular polarization
filters from RealD.  No electronics in the glasses, but a fast
polarization filter on the projector.  Less light to the eye,
because you are cutting both the image interval and the transmitted
light in half.

I'm guessing that at least some home 3D players will use NuVision.
The same old projection optics. Both systems require double frame
rates.

Perhaps we can ask Boyd to speak at a PLUG event, and local graphics
software folk can help him make Linux and perhaps open-source versions
of the graphics drivers.
