I'm hoping to eventually locate some X-Specs 3D which worked at television
frequencies. I think they plugged into the Amiga joystick port, and just
liquid crystal shutters. The 3D modes were done on interlaced screens,
with the image for one eye drawn on the odd lines, and the image for the
other eye drawn on the even lines. The shutters would activate in synch
with the interlacing.
I *think* these glasses are classic by now.
Some 3D rendering software actually generates images for these glasses
(Imagine from Impulse at least) and I think I saw programming libraries
for them on Aminet.
Ah... here are some games on Aminet:
LanderGame.lha game/misc 257K 344+X-Specs 3D Lunar Lander game
RaiderGame.lha game/misc 77K 344+Space strategy game for X-Specs 3D
No sign of the libraries, but I've seen them somewhere.
One of the original games that shipped with the X-Specs involved giant 3D
killer space potatoes. Space Spuds? One of the local Amiga stores <sigh>
used to demo that game.
There were also freeware/shareware games that used the red-blue 3D
glasses. The ones I used to play were "3D Breakout" and "Orbit".
Now all of the
hype is "3D". I have used some 3D illusion systems, such
as StereoGraphics. But all of the "3D" stuff that is being hyped is on
purely two dimensional video monitors. What's going on?
To get on-topic (I hope)... There were attempts at making 3D displays
using LCD spectacles controlled by the vertical sync signal to the
monitor. You saw one frame though each eye. It worked well, apart from
the flicker (even at about 100 frames/second).
Anybody have one of those in their collection? -tony
