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

hi, i've made a new branch in my repo : https://github.com/avilleret/Gem/tree/windows_stuff with some changes to build Gem on Windows with pix_share* objects this has not been widely tested for now, but it works with small images at least I will test it further more when I will have image and video plugins non-WIN32 code should be untouched + a -- do it yourself http://antoine.villeret.free.fr

[pd-gem:feature-requests] #51 buffer multiple textures on the GPU in one object
by Claude Heiland-Allen 15 Sep '13

15 Sep '13

--- ** [feature-requests:#51] buffer multiple textures on the GPU in one object** **Status:** open **Labels:** performance texture **Created:** Sun Sep 15, 2013 12:19 AM UTC by Claude Heiland-Allen **Last Updated:** Sun Sep 15, 2013 12:19 AM UTC **Owner:** nobody something like pix_buffer combined with pix_texture but that stores all the image data on the GPU in texture objects, indexable by number. I wrote an abstraction hardcoded for 10 images loaded from disk. the performance increase is dramatic. a proper implementation would be more like pix_buffer and related objects, with snap2tex support etc. --- Sent from sourceforge.net because gem-dev(a)lists.iem.at is subscribed to https://sourceforge.net/p/pd-gem/feature-requests/ To unsubscribe from further messages, a project admin can change settings at https://sourceforge.net/p/pd-gem/admin/feature-requests/options.

recent Gem for windows
by Cyrille Henry 10 Sep '13

10 Sep '13

Hello, chdh is in the process of releasing the patches used for the egregore performance http://www.chdh.net/egregore Shortly after, a live and distant performance will be made where the patches will be executed locally in order to have a good quality sound and images. Almost everything is ready, but we are facing a problem for the cross-platform compatibility. This performance needs the gem object gemvertexbuffer, that was introduced in july 2012. GEM 93.3 did not have this object (11.2011). So we are looking for a recent Gem binary for windows, since we already have linux and osx, so that we can distribute in the egregore application. or maybe a backport gemvertexbuffer extern for Gem. Better would be to create a 94.0 gem tag in order to have something a bit more recent for everyone to use. any idea how to solve our problem? thanks Cheers c

GLSL version of [pix_scanline]
by Jack 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
