Author Topic: Home 3D Michael Cornish Film Handler Posts: 26 From: Cincinnati, Ohio, USA Registered: Sep 2011 posted 01-02-2013 12:49 PM                     If you are going to be showing a BD 3D film using a projector, what is needed beside a 3D BD player? Do I need to get a filter? Silver screen?  |  IP: Logged Bajsic Bojan Expert Film Handler Posts: 190 From: Ljubljana, Si, Eu Registered: Aug 2008 posted 01-02-2013 01:21 PM                     Depends on your projector and what kind of system is available for it. Usually home 3d projectors use some kind of active system, so active glasses + IR transmitter. So first step would be to find out what projector you have, then we can see.  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 01-02-2013 05:24 PM                     It's not so simple. I'm not sure any projector is HDMI 3D capable. The "frame packed" HDMI video signal for 3D I've seen puts two images side by side on a 1080 HDTV signal. The 3D active glasses TVs split this into two images, scale them back to full screen, and then alternate them at 60hz with a glasses sync signal usually sent by an IR LED on the front of the TV. The TVs that use polarized 3D just show both images at once, alternate image lines have reversed circular polarizer built in to the screen. A 3D capable projector may only work with frame-alternate 3D that some game units and computer video cards produce. There are converter boxes that take the HDMI frame-packed signal and convert it to frame-alternate for projector presentation. They should also have a sync signal output or transmitter to make the glasses work. To do polarized 3D you need something like a Master Image system (Real D doesn't provide their systems for "home theatre" use as far as I know), and a way to generate the synchronizing signal, and a silver screen... not really an economical choice.  |  IP: Logged Mitchell Dvoskin Phenomenal Film Handler Posts: 1869 From: West Milford, NJ, USA Registered: Jan 2001 posted 01-02-2013 06:06 PM                     It depends on if you are referring to running Bluray 3D into a DCI compliant theatre projector, or into a consumer grade front projector. If you are referring to a consumer projector, there are a number of models out there that support HDMI 3D. All of them use active "shutter" glasses that will work with any white screen/surface. If you are referring to a professional DCI compliant projector, others here are more qualified than I to answer your question.  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 01-03-2013 01:47 PM                     I didn't realize there were now HDMI 3D home theatre projectors, I looked for one not too long ago and couldn't find any. Now I can find a bunch! If you want to show a 3D blu-ray on a cinema projector you will need a converter like the Doremi Dimension 3D, converting the HDMI format to dual SDI. There are probably other converters to do the same thing that cost less though.  |  IP: Logged Mitchell Dvoskin Phenomenal Film Handler Posts: 1869 From: West Milford, NJ, USA Registered: Jan 2001 posted 01-03-2013 01:51 PM                     Click Here to see the one I am saving my pennies for. Still a little too expensive, but I have seen this one and for home use, it is awesome.  |  IP: Logged Frank Angel Film God Posts: 5305 From: Brooklyn NY USA Registered: Dec 1999 posted 01-27-2013 01:10 PM                        Being an avid 3D fan, I too am looking for a way to do 3D in my home theatre setup. Yes, you can go the active glasses route, but that loads you with all the disadvantages of shutter glasses -- the amount of light they suck out of the picture, the weight (although I think they are getting better at that, some fairly lightweights coming on the market as well as some that are less pricy, but still, for supplying a decent gathering of friends with glasses, it's gonna cost you). But the worst thing with shutter glasses are the damn batteries, and how they can go dead in the middle of a show, especially if you have more than three or four to keep track of. For me, the only way to go is passive. But how? Simple, get TWO decent, but fairly inexpensive 2D projectors and a converter box that can take the HDMI signal and split off Left and Right eye signals and send each to the Right and Left eye projectors. You get the advantage of double brightness which you really need for 3D, plus you can use Real D glasses that you took home with you from the theater because YOU PAID FOR THEM. The one drawback, yes, you need a silver screen, and that will be more expensive, but in the end I think the advantages of dual projection outweigh the downsides. I also read that someone is experimenting with LCD projectors because LCD panels have their own naturally polarizing properties (take a look at your LCD watch or the LCD display on your car radio with RealD glasses on -- one eye will not see anything but a black screen). There is a possibility of using those properties to avoid needing to put an additional polaroid filter in front of the projectors thus avoiding that extra loss of light. It think this is a really interesting approach to Home Theatre 3D.  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 01-28-2013 04:45 PM                        The active shutter glasses I have are lighter and far more comfortable than any Real D glasses I've worn. They seem to suck up less light, too.  |  IP: Logged Antti Nayha Master Film Handler Posts: 268 From: Helsinki, Finland Registered: Oct 2008 posted 02-01-2013 01:58 PM                     As far as I know, the lightest active glasses are made by Panasonic and they weigh 26 grams. I think that RealD glasses are 21 grams, so a bit lighter still. (That’s not to say that they are necessarily more comfortable.)  |  IP: Logged Cameron Glendinning Jedi Master Film Handler Posts: 845 From: West Ryde, Sydney, NSW Australia Registered: Dec 2005 posted 02-03-2013 01:23 AM                     I use a cinema Panastereo 3d shutter glass system at home, that Ray made me up a special lead to work from (as it is a DCI system) and 1x Optoma 3d converter box. I have several 720p 3D ready projectors that work with this rig. The Panastereo glasses are quite light efficient especially compared to using polarizes on both the projectors and your glasses. The best bit is that no silver screen is required. My Panastereo rig is however currently rented to a commercial cinema. So I am currently using some very expensive Optoma shutter glasses which too work very well directly with the 3d link projectors. A warning however that the cheap 3d shutter glasses on ebay offer very poor picture quality and contrast. Another white screen option is using Dolby 3D glasses. You need 2 x bright hd (720 or 1080p) projectors (3000 lumen) , 2 x optoma 3d adaptor boxes, several Dolby glasses. Start by take one pair of glasses apart for use as the projector filters.  |  IP: Logged Marcel Birgelen Film God Posts: 3357 From: Maastricht, Limburg, Netherlands Registered: Feb 2012 posted 02-17-2013 07:13 PM                     quote: Cameron Glendinning Another white screen option is using Dolby 3D glasses.

Did you try this yourself? I guess if this works and how easy it will be is dependent on your actual choice of projector, because the filter should be installed in the light path. Also, I don't know if the filters in your glasses are sufficient heat resistant, even in a decent "home projector", it can become quite hot in there. The real filters in your projector spin constantly, even the "non-split" versions.  |  IP: Logged Frank B. McLaughlin Film Handler Posts: 76 From: Denver, CO Registered: Dec 2011 posted 02-18-2013 07:31 AM                        In setting up a custom system note that a majority of the devices now employ a HDMI 1.4 connection. In order to view 3D this connection must be used and both devices (server/viewer) must be compliant and "talk" to each other.  |  IP: Logged Joju Zacharias Film Handler Posts: 4 From: Changanacherry-city,Kottayam-district, Kerala-state, India Registered: Jan 2013 posted 02-18-2013 10:21 AM                     Hi I used a dual projection setup in my college for a 3d show. I used a desktop computer with Nvidia graphics card(vga+DVI+HDMI o/p), 2 DLP projectors(XGA) and Real-D glasses. I used the filter from the glasses to use in front of the projector, you just have to be careful enough to place it as far away from the projector lens(still passing the image through it) or it will burn out in 2 minutes. For making a silver screen I painted a normal screen with silver paint($4) and it worked very well. I used a side by side video, and stereoscopic player. you can use 2 O/P of graphics card for projectors and one for a control monitor. If you want to make a professional set up for a cheap cost use HD projectors and good graphics card(It will still be not good as a DCI system but costs 1/10 of it.)  |  IP: Logged Mike Frese Master Film Handler Posts: 465 From: Holts Summit, MO Registered: Jun 2007 posted 02-18-2013 11:28 AM                        This is what I am using and I am extremely satisfied with this setup.
