I'm looking into the 3d output possibilities with Lumion.

I have a question about that.

Lumion outputs a stereoscopic mp4 file. Is that file playable on a 3d tv? Will the 3d tv recognize the 3d file and display it in 3d so it can be watched with glasses?

I'm totally new in the 3d output/display area, so if anyone could point me in the right direction on the net, to learn more about this, that would be great.

Yes you can watch this on a 3d tv. You need a new nvidia card for that, for example the 580 gtx, a computer screen that supports 120 hz, special 3d glasses and than you can watch the stereoscopic movies with a special video player software (there are some free ones). Just search for Nvidia 3D vision. If you wanna watch the movie on a TV you need Nvidia 3DTV Play Software.

Is there a way to display a 3d movie on a 3d-tv without the use of a computer? (glasses off course are still needed)

What I mean is, are there 3d-tv's that allow you to plug in a usb stick and playback the file. Maybe stream the file to the tv?

Or are there no 3d-tv capable of converting the 3d-mp4 file to a 3d image to watch with glasses.

3D Blue ray comes to mind. If you are able to convert a 3D MP4 to blue ray that should work. You would need a TV with an integrated 3D blue ray player. How much hassle is it really to attach a separate blue ray player?

You can convert the movie file using a program called "stereo movie maker".  You can merger the file and output the format in Cyan/Red or interlaced etc.  If you look at the project i have in the gallery "Penn Hills..." the last post is an output from the program.  You can then put it on a DVD or Blueray or play it directly from WMP/ Quicktime without any additional hardware.  Let me know if i can help.  There is no stereo output for still images at this time (i personally would love to see it happen to present a static print for a client).

Hi folks!

if you want to watch on your 3d tv a movie file generated from Lumion follow these steps:

I got a Samsung 3d led, model C8000, and a Nvidia 3d Vision kit...but it's not necessary to have the latest GTX Fermi board to watch Lumion 3d movies, the modern 3D (not only) tvs can play directly from a usb dongle.

From Lumion you generate a 1920x1080 stereo image. It's a simple image that contains two frames squashed (anamorphic), the format is called stereo "side by side". The tv stretches the image so you will watch two alternated 16:9 frames. This format obviously has half resolution compared to a full 1920:1080 frame. The height (1080) is maintained.

I copy the mp4 file directly on my usb key then I insert the key on my 3D tv and choose the tv multimedia player. Every 3D tv has a button on the remote that can choose the side by side format...et voilà...now wear your 3d glasses...

There are also several 3D formats: Over-Under, side by side not squashed, checkerboard, interleaved horizontal, interleaved vertical.

IMPORTANT: I'm not speaking about anaglyph formats, these formats could be useful to print images on paper. This format uses coloured lenses to subtract colors from the image and generate the stereoscopic effect in our brain.

Unfortunately on modern 3D tvs you can't watch an mp4 multiview MVC format video, or a 3840x1080 fille (composed by two full HD frames 1920x1080 syde by side) from an usb key. You can't from DLNA hard disks or exernal multimedia players like La Cie or Western Digital.

Below the explanation:

To encode an mp4 multiview (extension to the ITU-T H.264 Advanced Video Coding (AVC) codec) file it's necessary to have an authoring bluray 3D software. Only few companies produce this special software, on the web it's impossible to find a free encoder/decoder and then burn a 3D bluray.

At the moment you can't master at home your 3D Bluray...

If you want to play full 3840x1080 video files you need a pc with the latest Fermi board a 120hz 3D monitor or 3D TV and the Nvidia 3DTV Play software that use the hdmi port with the 1.4 standard. With the optional software called Stereoscopic Player you can play any stereo movie you want.

Neither a Playstation 3 can play a MP4-MVC file copied on the hd, with a PS3 you can play, with an optional software called Play Memories, only mpo stereo photos (very impressive).

Unfortunately Lumion doesn't render 3840x1080 jpg files or movies.

 

Best regards

Gabriele

Thanks Gabriele!

That was the answer I was hoping to get.

So it is possible to display the 3d-movie generated by Lumion directly on a 3d-tv, that's great to hear.

I'll see if I can test this soon at the local tv-shop.

I just traced a major bug which prevents NVIDIA 3D Vision from working properly. I have 3D Vision up and running perfectly except for some minor glitches on the vehicles. Should be easy to fix. If all goes well the next version has perfect NVIDIA 3D Vision suport! :D

Great news!

and I hope you will give us the possibility to save the full 3d frame buffer. Theorically if I use the 2560x1600 anaglyph 3d vision mode I have two buffer and I can save a 5120x1600 image.

I think that Fraps can do this.

I'm not sure how saving of the 3D buffer can be accomplished. It would be great if Fraps can handle that. We use a direct capture card to capture the video image from the HDMI port but this method won't work for stereo because the capture card won't be able to handle the interleaved frames.
