SteamVR
This page will walk you through installing and running the steamVR driver. It is currently supported on windows, with linux support in progress. A Launcher/Installer is also in progress.
This steamVR driver is still a work in progress, if you run into any issues, please reach out on Discord.
Working with some polish needed
- Head Tracking - Hand Tracking - View Projection - Skeletal tracking - Basic input - T265 Sensor integration
Notable unfinished parts
- Gesture recognizer
Prerequisites
Versions of vendor libraries not included, here is where to get them:
You will need to install the leap motion multi-device drivers in order for this driver to work. - LeapDeveloperKit 4.0.0+52238
If using the structure core you will need the CrossPlatform SDK 0.7.1 and the Perception Engine 0.7.1 https://structure.io/
If using the intel realsense t265, you should install the Intel® RealSense™ SDK 2.0
Using prebuilt binaries
We have a prebuilt version of the driver available here. You can place it in the following directory, or use vrpathreg as shown below.
Generating Project Files
In order to build from source you will need to install visual studio 2019 with c++, .net and C++ modules v142. In addition you'll also need to install git and cmake.
All commands below are run in windows command prompt
In the folder in which you want the repo to exist, run the following commands:
Building the driver in Visual Studio 2019
- Open the generated solution and set northstar to the startup project (right click the project and choose the set as startup where the gear icon is) and build.
Make sure to target x64 and a Release build to remove any object creation slowness.
- The release will be in `build/Release/`and will be comprised of dll files.
- Copy all the dll's to wherever you want to install from, they should be combined into the `resources/northstar/bin/win64` directory, make this if it does not exist and put all generated dll's inside.
Initializing the Driver in SteamVR
- Next register the driver with steamVR (using vrpathreg tool found in SteamVR bin folder). This is located at
C:\Program Files (x86)\Steam\steamapps\common\SteamVR\bin\win64\vrpathreg.exe
vrpathreg is a command line tool, you have to run it via the command prompt. To do this, follow these steps.
1) open command prompt
2) run cd C:\Program Files (x86)\Steam\steamapps\common\SteamVR\bin\win64\
3) run vrpathreg adddriver <full_path_to>/resources/northstar
4) you can verify the driver has been added by typing vrpathreg in command prompt, it will show you a list of drivers installed.
- at this point vrpathreg should show it registered under "external drivers", to disable it you can either disable in StamVR developer options under startup and manage addons, or by using vrpathreg removedriver <full_path_to>/resources/northstar
- Running steamvr with the northstar connected (and no other hmd's connected) should work at this point but probably not have the right configuration for your hmd. Take the .json file from calibrating your nothstar and convert it to the format found inresources/northstar/resources/settings/default.vrsettings
- restart steamvr. If driver is taking a long time to start, chances are it got built in debug mode, Release mode optimizes a way a bunch of intermediate object creation during the lens distortion solve that happens at startup. If things are still going south please issue a bug report here:
- if you wish to remove controller emulation, disable the leap driver in SteamVR developer settings.
