Hey there,
I know this was recently rehashed, but of course I wasn't thinking too
much about it at the time (and now somebody has made me interested). In
any event, a colleague (go figure) of mine saw an article on projecting
stereo for a classroom. The way it works uses a dlp projector connected
to some sort of gaming graphics card (this was not for crystallography
but instead used for playing games). There is an emitter connected to
an inverter, and stereo glasses costing around $100 each.
The overall system sounds cheap (in a good way), and it seems to be a
reasonable way to do things.
Now, I of course want to be even cheaper and use as much of my present
systems as possible, and maybe just hook up the projector. Has anybody
tried to hook up a dlp projector to a linux box and if so, does it
project stereo as is (just as a crt monitor)? And, if so, do we need
the inverter thing or does a standard emitter used on our systems (any
of the usual flavors of emitters) do the job well. My thought is to
just buy the projector and try it (and then buy extra pieces if needed),
but I wanted to ask if anybody else has had success doing something
similar to this.
By the way, while on the subject, how do most emitters work (is it radio
frequency or ?????). I ask because I was playing with that the other
day and found that I could sit a far distance from my computer (over 15
feet, which is the extent of the room) and still see in stereo. Does
one need to look towards the emitter to have it work (they sit on top of
our monitors now and so I never really thought about it) or could one
possibly just have the emitter in the room and have people looking
towards a wall that is on the opposite side of the room as the emitter?
This obviously relates to having a computer project from one side of the
room and look at a stereo figure on the other side (with an emitter -
where do I need to put it - I don't have a long enough cable at
present). I know there are issues with people using multiple
workstations in the same room, but it seems possible to me that if they
are all at the same frequency that it wouldn't matter. I've never had
issues with multiple computers, all right next to each other, but I've
heard rumors :)
Thanks. If anybody is interested I'll dig up the web site where my
friend found this. It has to do with projecting 3D gaming applications
to a group of people.
