[GEM-dev] Oculus Rift distortion/support

[Michael Mihocic]

Dear list,

we are using GEM with a head-mounted-display to present a virtual world 
to subjects performing acoustic localization experiments.

Now we plan to switch from our current HMD to Oculus Rift (an upcoming 
virtual reality head-mounted display). Therefore we need to modify our 
image and add (asymetric) barrel distortion to the represented image. 
(The image distortion is compensated by the lenses in Oculus Rift.)

My questions now:
- Is there an easy solution to implement barrel distortion to the 
rendered window in GEM?
- Does anybody of you already have some experience with GEM together 
with Oculus Rift?

Since attachments should be avoided in this list, I do not send any 
example pictures of the distortion or our current presented world. If 
you are interested you can either contact me and I can send you some 
screenshots, or you can google for example images/videos of Oculus Rift 
distortion.

Thanks in advance and best regards, Michael
