Developer forum for the OSVR plugin for SteamVR, providing SteamVR support for OSVR HMDs.
they use this distortion model https://github.com/OpenHMD/OpenHMD/wiki/Universal-Distortion-Shader and provide a GLSL shader for distortion with these 4 values
though only the rift dk1, dk2 and cv1 have good values so far and the Deepoon E2 may read correct distortion parameters from its config on the device
well steamvr puts some 2d coordinates into plugins and expects them to return distorted coordinates and I figured that's pretty much what their fragment shader does, so I translated that to C and it works https://github.com/ChristophHaag/SteamVR-OpenHMD/blob/master/driver_openhmd.cpp#L623
So the steamvr-openhmd is the first attempt at bringing openhmd to steam?
I think OSVR also supports building a distortion mesh from sampling, just like SteamVR so the same method for distortion correction should work for OSVR-OpenHMD, and then I would have to look into how to get the rest of the display parameters into OSVR without config files
OpenHMD's long term plan involves creating a rendering library OpenHMD-gfx or so, that can then also do direct mode etc but not much has been done yet
DirectMode works (at least the last time I tried) with steamvr-osvr
if that lands, then all is upstreamed https://lists.freedesktop.org/archives/mesa-dev/2018-March/188116.html
rumor is it's being made into an OpenXR runtime
Kind of like OpenGL.
basically like this https://www.youtube.com/watch?v=4VixbQ9DIW0
Do u have nolo?
that's what the video was about
no, I only have a Vive and HDK2
I did put libsurvive into OpenHMD but ugh https://www.youtube.com/watch?v=Hgtagc17AAI
hmm the osvr branch is too old to compile with SteamVR-OpenHMD. gotta update that
thats too bad
