LuxVR: Virtual Reality with LuxRender (and OpenCL) back

I have uploaded a video about an ambitious project I'm working on at [LINK http://youtu.be/JrvyjqYX6o8]
LuxVR is a LuxRender project to introduce the interactive experience as a new kind of media produced by traditional off-line renderers. You can find some detail and the ongoing discussion about this project at [LINK http://www.luxrender.net/forum/viewtopic.php?f=34&t=9604].
Technically, it is a combination of SLG ([LINK http://youtu.be/jk-N4f9ze4k]) OpenCL path tracer and Sfera ([LINK http://youtu.be/Dh9uWYaiP3s]) OpenCL image pipeline with tone mapping, gamma correction, frame blending and blurring (in order to reduce the perceived image noise).

I have uploaded a demo video of LuxVR working with Oculus Rift HMD ([LINK http://www.oculusvr.com/]): [LINK http://www.youtube.com/watch?v=QiW24tahE7I]
P.S. indeed, the video is supposed to be seen fullscreen with Oculus Rift HMD.

That is all kinds of awesome. I wonder though - what does the progressive update feel like when you're actually using it with a Rift? Must be a slightly crazy experience [SMILEY :D]

Yes, you need some kind of automatic Camera locking and/or user controlled locking. Another possible option would be to use some kind of heavy filtering of data coming from the head tracking device. However, heavy filtering can introduce some serious motion sickness problem and should probably be avoided.
Without true hard real-time path tracing, it is going to be hard to make any effective use of the tracking device.
However, even if used only as display device, the Oculus Rift is going to be a good product (especially if you factor the cost).

I would strongly suggest reprojecting pixels under rotation only. It will speed up convergence like crazy when used together with a helmet with lots of small head movements all the time. If you want to be tricky you can focus all the new pixels that comes into view. Will even give a smoother translation if you are using frame blending.
