no 6dof, and i don't even own the controllers or camera, but hey, 3dof works! (side note: if you have 3glasses 3wand controllers, please let me know! i want to add support for those too)

Monado Blubur S1 driver Beyley Cardellio (LyrisTheKitori) published a post on Ko-fi

wruf, hello all! 🐾

spent the past couple days working on a lil silly thing for a lil silly HMD, a Monado driver for the Blubur S1!

as an addendum to my post earlier, i wrote the libsurvive integration for my Vive Pro 2 driver, and i gotta say it works really well!

YouTube video by Beyley Cardellio (LyrisTheKitori) Monado Vive Pro 2 driver complete*

you can read about the work on my Ko-fi, and watch a video of me playing beat saber with it, and finally getting my first "wow!" moment with VR, the immersion of a large FOV really does make a huge difference

arf arf! 🐾
as of today, i've just completed the MVP for the Monado Vive Pro 2 driver! distortion and FOV for most units should be 1:1 exact, and i've even wired up the little things like brightness

if you want to support my descent into mathematical madness reverse engineering the Vive Pro 2 distortion algorithm, or any of the other VR work i do, please don't hesitate to support me on Patreon or Ko-fi! 🐾

i was unable to find any myself, but if anyone has a description of the algorithm in full, or has details that can help the reverse engineering effort, please pass that info my way! you can find me in the Monado discord working on this
discord.com/invite/um7xR...

i've managed to isolate and implement the core algorithm, at least to the best of my knowledge, but figuring out the math *surrounding* the it has proven tricky, with >60 hours so far spent on this. slowly getting there though!

after a little over a week of bashing my head against it, i've managed to make a fair amount of progress on reverse engineering the Vive Pro 2 distortion for Monado! 🐾

i've got the data parsed out, but the algorithm is incredibly complex with many moving parts

tomorrow, i hope to get the special vive pro 2 config loaded, implement the in-house vive pro 2 display distortion, and maybe make some more headroom on the IPD, since it's Different

speaking of IPD, anyone have an idea how to parse these
IPD: 2 (min: 499, max: 3581, lap: 3922)

my progress today is fixing the flipped displays
gitlab.freedesktop.org/monado/monad...
and opening the HMD's special interface and setting the display resolution to a safe one
gitlab.freedesktop.org/monado/monad...

i can properly play games now! ...if i hardcode the IPD

arf! hello everyone
got a new VR headset today since my Quest 2's battery is unfortunately starting to bite the dust
found a cheap Vive Pro 2 and decided to go for it! the support in Monado is very sub-par but luckily there's a good community SteamVR driver i can reference

anyone with both a Logitech MX Ink Stylus and a Rift S willing to help a girl out with something cursed?

Quest 2 controllers can be paired to Rift S (and even can be 6dof tracked under Linux!), and the MX Ink Stylus *also* pairs to quest 2

i think you get the idea i want to try

for more Monado related things, to fulfill the needs of Resonite, i've been designing a set of OpenXR extensions for Monado to cover the needs of arbitrary trackers and device battery info
they're still unfinished and there's still discussion on details, but i'm making progress!

it's written in Zig, and uses SDL3 + a forked SDL GPU subsystem with VR support, see attached video for the first time we actually got a scene rendering!

hey! 🐾
been a bit, and been hard at work on a couple things, that haven't been interesting enough for dedicated posts, however i've hit some cool milestones that i would like to share now!

past couple weeks i've been working with a friend on a 3rd-party renderer for Resonite!

now that all this is working, i'm going to start writing a yaw correction tracker using the camera data, then after that works, start to upstream the driver into Monado

more VR Wii Remote driver progress 🐾
over the past couple days i've been working to get 3dof, button presses, and other parts wired up to OpenXR so that applications can be run, and I have it working now! rotation data is passed to applications (see video attached later down)

god bless random person from a couple years ago on stackexchange who was doing *exactly what i was doing*, and wrote down how they solved it!

next is to read the calibration data from the extension, parse out the gyro data, and integrate the gyroscope and accelerometer data into a 3dof pose!
very glad to finally be past that big hurdle towards progress on the VR WiiMote driver
excited to work on the IR camera trackers soon!

Screenshot of binary data being sent from a Wii Remote, containg 6 bytes of extension data from the Wii Motion Plus accessory, which contains 3-axis gyroscope data.

small update, no video this time 🐾
after a *lot* of effort the past couple days, i *finally* have Wii Motion Plus data sent to Monado! turns out the kernel kept turning it off automatically, so i wrote a new L2CAP HID implementation for Monado, bypassing the kernel entirely

apologies for the poor audio! i've still yet to find my voice with things like this, and also there was noise + bad mic placement, will try to get better mic placement next time!

hey! i figured i should start chatting about what i've been working on more often, so here we go!

today, i've been working more on my VR-focused Wii Remote driver! got the IR LED data read, fixed bugs, and have a solid plan on how to move forward!! 🐾
