@siguza @rotopenguin @zhuowei This is the best I could convince it to respond with...

@jschauma (I just had to look it up, here's the explanation I found: https://stackoverflow.com/a/7576975)

@simon ... if you just got it, how is it so dirty already? And how can you stand not dusting your laptop?!

@zhuowei Do you think it would be possible to plug in 3DOF tracking into the simulator? and perhaps get it to output in 3D SBS?

@zhuowei @ShinyQuagsire I only have a #NrealAir, but it would be especially cool if the background was just black, since then the transparent OLED would pass through without the fancy cameras (though obviously worse, but also $3000 cheaper)

@zhuowei Any luck yet? I think that the way to do it might be in the xrOS .simdeviceui? I'm not having great luck with it because I'm bad with Swift stuff, but I'm seeing all the interactions (hover, orbit, etc)...and it seems to be interacting with a standard RealityKit CameraPerspective somehow hooked into the simulator?

@zhuowei Well, I tried just replacing the .simdeviceui with one I compiled, but ofc Library Validation is in my way...Not sure what the cleanest way around it is, either resigning the simulator with the disable library validation entitlement or see if I can somehow create something to patch it in at runtime...EDIT: Just realized that sudo defaults write /Library/Preferences/com.apple.security.libraryvalidation.plist DisableLibraryValidation -bool true still works, for some reason I thought that was removed. Yay!

@ShinyQuagsire Yeah, I figured that part out. When I try and replace it, I now get an error like this...Failed to load simdeviceui bundle for device SimDevice : Apple Vision Pro (E6C5AC55-1A25-40D7-ABBD-1799DF149581) : state={ Booted } deviceType={ com.apple.CoreSimulator.SimDeviceType.Apple-Vision-Pro: SimDeviceType : Apple Vision Pro (com.apple.CoreSimulator.SimDeviceType.Apple-Vision-Pro) } runtime={ com.apple.CoreSimulator.SimRuntime.xrOS-1-0: SimRuntime : visionOS 1.0 (1.0 - 21N5165g) - com.apple.CoreSimulator.SimRuntime.xrOS-1-0 }: The operation couldn’t be completed. (SimulatorKit.SimDeviceUserInterface.LoadError error 1.)Not sure how to debug it, "error 1" isn't very useful...

@ShinyQuagsire @zhuowei I now have https://github.com/JJTech0130/XRGyroControls loading! Now I need to actually implement functionality, but I at least know my functions are being called.(The Xcode project is a mess, as usual, so it probably won't build for anyone not on my machine...)

@keithahern @ShinyQuagsire @zhuowei Well, I'm making progress. I actually think I'm managing to send HID messages, though there isn't any reaction right now because the messages are nonsense.It's a bit slow since I barely understand SIMD stuff, and the poses do complicated math with it, but I think I should be able to get something that just resends pre-calculated messages soon enough.

@keithahern @ShinyQuagsire @zhuowei Ok, definitely making progress. XRGyroController can now flip camera directions on a timer. I need to figure out the actual pose math, but for now it can replay the final bytes and get it to go to that position!EDIT: WOW, I was dumb. All the complicated maths was irrelevant. Format is literally X, Y, Z, 1.0, Pitch, Yaw, Roll, 1.0EDIT2: :tada: XRGyroControls can now tell it to go to an arbitrary XYZPYR pose. Next step, the pointer.

@keithahern @ShinyQuagsire @zhuowei so... making progress? dunno if you guys read the comments on my latest commit, but basically I got the sending of the manipulate HID command working, but I don't understand 3D maths enough to actually get it to work with a mouse cursor.Maybe it could directly be fed eye tracking data, but I don't have a headset with eye tracking.I guess tomorrow if nobody else does it I will watch a lot of YouTube until I understand the 3D stuff.......

@zhuowei Uh, so... noticing in the IndigoHID stuff it's possible for it to send a "DigitalDial" event: is this related? In SimulatorKit there is a mention of "DigitalCrown" events too but xrOS doesn't use that, only DigitalDial

@zhuowei Well, now I'm a bit conflicted at how to proceed. I was originally trying to use the original system as much as possible, so I made a proper .simdeviceui and .simdevicetype so that nothing is patched, you just select a different device type. So I could replace the entire .simruntime for XROS too... but hooking it seems way easier, especially if it doesn't require disabling SIP or library validation...

@zhuowei also... can dyld interposing be done with Swift stuff?

I just came up with the coolest trick for debugging system LaunchAgents, the ones that appear and disappear so fast you can't attach:cp /System/Library/LaunchAgents/com.apple.imtransferagent.plist ~/Library/LaunchAgentsOpen the plist in Xcode and add WaitForDebugger: YES to the root of the plistlaunchctl unload /System/Library/LaunchAgents/com.apple.imtransferagent.plistlaunchctl load ~/Library/LaunchAgents/com.apple.imtransferagent.plist(replace com.apple.imtransferagent with your LaunchAgent of choice)
