Oculus Rift distortion/support
by Michael Mihocic 18 Sep '13

18 Sep '13

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 -- Michael Mihocic Psychoacoustics & Experimental Audiology Acoustics Research Institute <http://www.kfs.oeaw.ac.at/> Austrian Academy Of Sciences <http://www.oeaw.ac.at/> michael.mihocic(a)oeaw.ac.at

GLSL version of [pix_scanline]
by Jack 07 Sep '13

07 Sep '13

Hello, Here a GLSL version of [pix_scanline] with its help patch. Can be integrated everywhere if needed. It could be interesting to have, in the help directory, abstractions with GLSL version of pixes, no ? ++ Jack

Hello, [pix_multitexture] seems to work only with normilized texture. Am I right ? It would be nice to have a [pix_multitexture] working with rectangle texture (if possible). ++ Jack

by "IOhannes m zmölnig" 16 Aug '13

i don't think this is a problem that can be solved on the Gem side. most likely it's a conflict between libvlc and libmagick++ that has to be resolved on their side.
