3D from the Radiance is not yet a given so no promises yet. Lumagen may still encounter an insurmountable obstacle that kills the project. But that being said...

I just spent a while talking to Jim Peterson of Lumagen. He informed me that the next major release being worked on for the Radiance processors is 3D. Right now everything is tentative and not defined, but here is the information I have now.

-The 3D upgrade will cost $199.
-The processors should be set to 120Hz output for CRT applications.
-The upgrade is scheduled to be released in one month (hopefully).
-Lumagen may still run into problems that spoils the project entirely, but right now things are looking good.

Here are some bigger questions...

-The trigger output on the XE and XD might work as an output to an IR transmitter to drive 3D glasses with CRT!!!
-Lumagen will only attempt this if there is demand, so if you want this triggered glasses support (and all CRT people should) please post your comments to this thread and I will pass them along to Jim.
-Since the XS does not have a trigger, the XS is not planned to drive glasses at this time.
-The XE and XS have a better chance of working 3D in the end because they have the newer chips.
-But Lumagen will try and make the XD run 3D as well.
-If the IR glasses trigger works, it will work on the XE and XD, if the XD can run 3D at all.

I'll be doing some testing here for Lumagen soon I am sure. I have a media server that supports 3D and an XE here along with my G90. I already have 120Hz running and set up on the G90.

Please feel free to post any questions or comments and I will try and answer them (if allowed by Lumagen) or I can ask Jim if I don't know the answers. This is still Alpha development right now so I am not allowed to disclose all that I know and Lumagen has not divulged everything they are working on to me in its entirety.

And like I said, 3D from the Radiance is not yet a given so no promises yet. Lumagen may still encounter an insurmountable obstacle that kills the project. But right now Lumagen believes that this will work.

if one would blend 2pj`s can the lumagen handle 2 times 1920/2 + 5% overlap *1080 @ 120hz on 2 hdmi outputs?

for a blend all you need is the a lower res any how, i use 1064x800p@72 hz now from my Tv-One I tried it at 96 hz with that res and it still looked good, a bit softer but very smooth and I tired 120 hz with the same progressive scan rate, this is where it softened up. I will have my XS's before the tv ones.

A stack would be totally different, maybe have each image shut off to each PJ , this would then replace the glasses as now the PJ's them selves would become the shutters . now the speed of the image flash is whats critical, or it might not work this way at all.

Cool, I called this in the 3D thread! I should be a marketing guy!

[dvh99]

the ultimate device would be of course a vp that can blend and send the required resolutions over the 2 outputs and support 1080p@120hz on 1 output (this of course for the next gen dig pjs).

Ok, so I am saving my pennies for a Radiance, but I don't need all of the inputs and outputs of the XE, the XS (more specfically the XS+) is perfect for me and the number of sources I have. I see that it doesn't have the external trigger, so 3D is out? Is there anything else about the XE that is different from the XS?

This post should probably be in the Radiance thread and maybe I need to call Lumagen myself, but before I make an investment like this, it would be nice to know what Lumagen is going to do for updates and upgrades for it in the future, if any.

I have seen in numerous posts about 3D for crt projectors discussions about the bandwidth limitations. On several of these posts I have seen recommendations for using an interlaced signal at 120 Hz. which would effectively cut the bandwidth requirement in half.

BUT - I can see a problem with using interlaced signals that hopefully someone can help me understand. Since the interlaced signal is actually two separate 1/2 resolution images (even & odd lines) each scanned during 1/2 the total time period; when using shutter glasses, depending on the shutter rate, either only 1/2 of the resolution will be shown as the shutter will switch eyes or there will be no 3D effect as the even lines will be seen by one eye, and the odds with the other.

Sorry that I am not able to describe very well what my concern is, but maybe someone can describe it better. I have even confused myself!

I do have some interest in trying 3D because, as Athanasios pointed out, with a blend, you have already cut down the bandwidth issue by almost 2 to 1.

Guys!

I still think home 3D will be a short-lived fad, forgotten in a year or two. First, CRT projectors will need P43 green phosphor or the lag problem will put ghosts all over the screen. A nine inch Marquee tube in P43 is near $4400, approaching the value of a used projector itself. P43 gives up about twenty percent of the light output of standard green. You will lose thirty or forty percent light output through polarizers or shutter goggles. Polarizing requires metal foil screens. Shutter goggles become extremely uncomfortable after fifteen minutes, worse if the viewer wears them over regular eyeglasses. The whole thing is way impractical. Even for free, I don't want 3D.

i have a p43 green tube so i think i will give it a go and see the effects.
any recommendations on movies on which the 3d is implemented well.
