Hi guys, I am sorry I left this thread unattended.
It is clear to me that we are at the beggining of this...not sure how to call it, technology or workflow. Probably in a short time we won´t have to be looking for workarounds and there will be options straight from the renderer that will work with any device we need. On the other hand, the most common reaction from the prospective clients that put the glasses on for the first time is: Can I move in here? So we have decided to invest some learning time in Unreal Engine (it still does not offer easy export to any device, but we are confident it will be soon), but that is a different topic.
About Holodeck 360 app, they released an iOS version, so those are good news. But as Francisco pointed out, KRPano is multiplatform (web-based) and also allows to make virtual tours through hotspots, which is a very interesting feature to connect different spaces of the same project.
To use the cubic output from V-Ray in KRPano (I can imagine Lumion is exporting the same format) we need to split each one of the squares and mirror them. KRPano needs to be feed with each square image, so it will create the panorama for you.
I created an action in PS to do that, but it is just a matter of identifying each side of the cube, make it a single image, mirror it, and rename with a letter in the end so KRPano will know its position (_l:_r;_u;_d;_f;_b):(left, right,up, down, front, back). If you want to use a different image for each eye,then also add (_1;_2) after the name so it will be left or right. And before we feed KRPano with this images, we need to change the .xml file in a couple of lines. It is explained in KRPano forums.
So..it is far from ideal, but for now it works.
