1 year ago Pico 4 Headset
i have the same Pico 4, migrated from a Quest 1 and uninronically tried again to implement offsets due to this. I backpedalled on it when i found an accidental fix. I use Virtual Desktop for PCVR and when i run steamVR from VD, it runs in a way that any following OpenXR aplication will have screwed offsets... BUT if i run the steamVR.exe directly (can be run from the steam client instead of VD) it runs in "oculus touch emulation something" and it sees the controllers as a pair of oculus touch, with "correct" position and rotation. (regardless that is very lazy of my part, but try it if you can)
As such - I had a bunch of issues with even the un-modified program refusing to compile
My bad, i should have provided compiling instructions since the whole thing was jury riggged in like 10 hours.
- Edited using the IDE codeblocks (yes i am old), it is a bit relevant because the "solution file" is the makefile effectivelly.
- Compiled using the msys2 mingw-x64 compiler, it probably wont compile with the microsoft VC compiler.
- you can download the src+"codeblocks files" (a bit newer than the one published) in the attachment.
position offset would be nice
indeed, i actually tried to pull that off but either my math sucks (more likely) or i have the wrong data to produce the solution. (less likely)
The src i sent in the link actually does show a vertical offset because that is what annoyed me the most, really crap to look into ironsights that much above where they should be... So i tried and got stuck on this:
if i add "+10cm" to the Y coordinate, that is added after my hand rotation (why? i dunno), so the hand position looks corrected when aiming the index finger at the horizon, but if i point my index "UP", my hand position gets shifter "+10cm to my face instead of UP", so something around "rotate the positional offset matrix before applying it?" i didn't figured that out.
(check the code around main.c: 1476 on the attachment as a starting point)

Easy enough thing - I've found a use-case for Controller Position Offset XD
Due to an issue between OpenXR and the new(ish Pico 4 Headset, it has some serious issues with offsets - the controllers being offset from the hands by a substantial amount, both in position and rotation. From my testing it depends on the game - normally being 20 degrees tilted upwards (inYaw), and anywhere from 5mm to a full fist length (around 10-20cm) upwards (towards the thumb, don't remember which x/y/z coord that is rn).
I had a go trying to add Position Offset adjustment myself, and while it seemed easy enough I couldn't test it, and there's likely some problems given I'm far more used to C# than I am C/C++. As such - I had a bunch of issues with even the un-modified program refusing to compile, stating that the OpenXR include files don't exist - despite me adding the OpenXR SDK in what I think was the correct way.
So, in short: position offset would be nice, I tried it and have no idea what I'm doing, and the compiler is complaining that files that exist actually don't.
