Yes, Light field export is an option we are working on adding to the cloud service to allow you to have head or body movement within a volume. This will take more GPU power to render than fixed point VR, and the raw uncompressed data is pretty large. However, the codec we have built squeezes down a 1 m cubic light field (more than enough for head tracking while sitting down) to < 32 Mb at near lossless quality, including HDR (for tone mapping at playback).

We plan to support animation, multi-light and render layer support on top of stereo panos and light field output.

Does the Oculus 360 App also support precomputed panoramic animations or stills only?

It definitely supports panoramic animations and I think it also supports panoramic animations in stereo.

A fast question about the cubemap projection. Until the oculus 360 app is ready is there a way to use octane cubemaps in krpano?

From my understanding the cubes should be Front, Back, Up, Down, Right and Left for each eye. I chopped the render into 1536 cubes but could not get the cubes to align.

I did get the Stereo Left/Right to align but the Eye Distance may be off. I thought it could be .065 on the right render and an additional .065 for the left?

No issues with just a plain pano render except the fact that is not stereo, and that is the point of vr

thanks in advance

Hi Marcus,
there is a note on the tweet that says "Note that the modified Oculus 360 Photos app for stereo cube viewing isn't public yet, but mono equirect works on older one."
Does it mean that I can not view stereo 360 images yet. I have a Gear VR on the table and need to feed it for a presentation for a client. Any help appreciated.

Yes, that's what I said before:

Thanks for the swift reply Marcus.
Ok, lets hope that stereo will be supported soon. Makes sense for a VR glass ;)

What are you trying to do? You can't chop a spherical projection into cube mapping. You just have to render it out using the cube map projection, which is already possible in 2.21.
