spayne / soft_knuckles Goto Github PK

hi,
just stumbled over this upcoming arduino vr project https://www.reddit.com/r/SteamVR/comments/g30lng/arduino_index_controllers_free_head_tracking/
(auther says it will be opensource) and regarding linux compatibility he mentioned your soft_knuckles.
I had to make some minor modifications in order to build your code under linux:

Prop_LegacyInputProfile_String is deprecated so I replaced it with Prop_InputProfilePath_String in soft_knuckles_device.cpp. no idea if this is correct:

     for (uint32_t i = 0; i < m_num_component_definitions; i++)

WatchdogWakeUp requires an argument now, so this change was required in soft_knuckles_provider.cpp:

+        vr::VRWatchdogHost()->WatchdogWakeUp(vr::TrackedDeviceClass_HMD);

     }
 }

the bundled make_linux.sh just builds the objects but doesn't link a shared lib, so I created a quick&dirty (hardcoded openvr header path) CMakeLists.txt:

cmake_minimum_required(VERSION 2.8)
project(soft_knuckles)
INCLUDE_DIRECTORIES( "/usr/include/openvr" )
SET(SNSRC
	dprintf.cpp
	socket_notifier.cpp 
	soft_knuckles_config.cpp 
	soft_knuckles_debug_handler.cpp 
	soft_knuckles_device.cpp 
	soft_knuckles_provider.cpp 
	)

add_library(
	soft_knuckles
	SHARED
	${SNSRC}
)

builds fine here and creates a libsoft_knuckles.so
haven't tested the result, but maybe it is of some use :)

I followed all instructions in the readme, built the project changed .bat installation strings, ran it, and it seems the dll factory is not being called by Steam, so nothing happens after that (including not being able to use telnet to localhost 27015).

I also tried the sample driver from OpenVR, but for some reason all calls to UpdateBooleanComponent just return VRInputError_InvalidHandle, even with the original code version. I had already tried your driver before, but never could put it to work. I put some DriverLog calls inside some of the functions, including HmdDriverFactory and nothing comes from there, showing it's not being called.

Is there something I may be missing about the installation process?

The soft knuckles driver and debug client works and appears in SteamVR Home, however the controllers do not appear in any game which supports the valve knuckles controllers (Aperature Hand Labs, The Lab, etc). I have a suspicion that it is because the game needs to detect the controllers as Valve Knuckles, however I do not have the correct model number to put into the OpenVR driver to test this theory.

I finally managed to install and use the soft knuckles driver perfectly, however, I'm facing a small issue: I am updating the position and orientation of each controller inside SoftKnucklesProvider::RunFrame() using vr::VRServerDriverHost()->TrackedDevicePoseUpdated(m_knuckles[0].m_id, newPose, sizeof(DriverPose_t));, which I can visually check is happening without any problem, but I can see each controller keeps alternating between the position and orientation I just gave it and the position and orientation it starts when initialized.

I can visually see each controller constantly alternating between these two states. Would you know what may be resetting the controllers states and how to avoid it?

Hey there, thanks for making this.
There's actually a bit of a bounty I want to put together for a universal software driver for the vive TRACKERS using off the shelf cameras so that vrchat and other applications can have full body without the purchase of vive trackers.
There's extremely fast, accurate, and dense realtime pose estimation from commodity RGB cameras and other devices like low light and colour led available now thanks to pytorch and other RNN, but there's nothing to take a joint/foot/etc and emulate vive trackers.
Your driver seems absolutely perfect, what would it take to pipe data from a video stream to it and make steamVR see it as a vive tracker rather than knuckles?
Software like this could then be used to pipe in data to it:

Hi,

First of all, thanks a lot for the driver, there is way too little examples for SteamVR drivers out there, so I'm sure this will help many people a lot!
Sadly, it doesn't seem like the Knuckles driver from Steam can be downloaded without pairing the real Knuckles controllers first, is there maybe a different way of getting the rendermodels?
Also, I wanted to ask if you're going to try to implement the Skeleton as well, and if so, what the approximate timeline for this is going to be?

Thanks and have a good day!

I feel that the soft_knuckles title doesn't fully express what this utility can do, perhaps OPVRD? (openvr driver)

I have built the base driver and added it to SteamVR, however, there are several problems. Firstly, the driver is only adding the left controller (see screenshot below), the controller models are not appearing in VR, and the debug client does not seem to be able to interact with the driver, activate buttons, change pos, etc.

EDIT: had numdevices set to 1... the other two issues still stand.

Does the driver still work for you ?
Cause not for me.
