I want to create a 3d cinema business on my origin country, maybe 100 people on a area of 27 x 12 yards.
Option 1
OPTOMA DLP TX779P-3D (5000 Lumens) $1300
Volfoni smartcrystal pro + $1500
Chinese manufacturer gray 3D screen of 5 x 3.75 yards + $450
100 units of real d glasses from ebay $100
Total = 3350
Option 2
2 x OPTOMA DLP TX779P-3D (5000 Lumens) $2600
Chinese manufacturer white screen of 5 x 3.75 yards 250$
100 units of real d glasses from ebay $100
Omega system $?
1. My first Option will work fine with a screen that big? If not what will be a maximum good size?
2. Real D glasses are around 1$ is there a better glasses for that system not too far from that price? Wish ones?
3. What is the Price for the complete system of crystals, hardware mount and geo box and any other necessary accessories?
4. Pros and Cons of each setup?
Any help will be very appreciated
Thank you
There are some real problems with both of these setups you have proposed, I will try to point you in the right direction.
1. The OPTOMA DLP TX779P-3D is a business class projector, I highly doubt that it puts out 5000 lumens for colors, that is probably the white output rating. In the real world the RGB light output is probably far less. That projector is has a resolution of 1024 x 768 which is fine for movies and tv shows with a 4:3 aspect ratio, but that is very rare these days, most of what you will be watching will be 16:9, 1.85:1, or 2.35:1 so a projector with a resolution of 1280x720 or 1920x1080 is much better (and will waste less light).
2. Real D glasses will work with your first setup, but not with the second one. The Omega uses its own glasses, I am not sure what the glasses will cost in bulk like that, maybe ~$15 per pair (check with motorman), so this could be a significant cost.
3. This is too complicated to figure out just yet.
4. I personally love the Omega setup, but with 100 people you definitely want to use a polarizing setup (primarily because of the glasses cost).
If you are serious about making a screen for 100 people then you will need a professional class projector. My recommendation is to look around and try to find 2 barco, digital projections, or christie projectors with a lumen rating higher than 5000 (their lumen ratings are more reliable than the optoma business projectors). If price is an issue, you may be able to get a lower resolution model (720p) for a lot less than the 1080p ones. Someone else might want to chime in here, but I think if you get an LCD projector you can often use a quarter-wave plate to create the proper polarization with a lot less light loss than a DLP model. You will also need a geo box or something like that to split the stereo signal to two projectors. I'm sorry I can't give more specific advice on the projectors, but perhaps someone else here has more experience with larger venue projectors can point you in the right direction for a projector. I am not sure you will be able to find a single projector solution with the Volfoni that will be bright enough (remember the projector still need to accept a 3D signal to use the Volfoni, so that limits your options).
