20 years ago,
StereoGraphics in San Rafael was NOT getting rich on their
"Crystal Eyes" LCD shutter glasses. ?They were using SGI workstations at
Around then (I think it was 1988)(, I got to try a 3D imaging system
using LCD shutter spectacles. The flicker drove me mad (it was very
noticeable), no way could I have worked with that for very long. I
assume they've increased the frame rate by now.
I do have a couple of sets of LED spectacles and the (fairly simple)
control unit for use with muy E&S PS390. One day I must get round to
getting all that working again...
nVidia's setup is a 120Hz screen, ergo, I presume, 60Hz shuttering.
Flicker was rarely noticeable, but then, I am not at all sensitive to
such things.
I suppose the difference is now that any games-capable recent nVidia
card will do it & the bundle of wireless specs (estimate battery life
is on the other of months between recharges) and screen is ?250-300 -
for a 24" widescreen. I am guessing 20Y ago, you could have added at
least 1 zero on the end of that...
