This was long requested and it's finally here! Latest VVVV.OpenVR can use vive trackers without HMD (head mounted device). There is a dedicated pose output on the Poser (OpenVR) node and you can request the serial numbers of all connected devices.
Here is how to get started with high-performance 6DOF positional tracking for as little as $230 bucks. Minimum hardware requirement is one base station and one tracker. Although two base stations are recommended for much better tracking stability.
In order to get the trackers running without HMD you need to do the following steps:
Find this file on your drive:
Then open this file:
SteamDirectory is usually C:\Program Files (x86)\Steam.
Also make sure to disable the "SteamVR Home" on startup. Otherwise it will try to render into the null HMD and consume 100% of one CPU core:
If SteamVR was running, close and restart it.
When SteamVR restarts, you can connect a tracker or controller without the HMD. Follow these instructions to pair the trackers ("Pair Tracker" is now "Pair Controller"): Pairing Vive Tracker
SteamVR should then look similar to this:
Note: The red “Not Ready” text can appear occasionally but that should be no problem if you are using the null driver.
If you don't run the calibration process, the first found vive lighthouse base station will be the origin of the tracking space. If you can live with that you need to provide your own calibration matrix in vvvv and multiply it with the pose matrices coming out of the Poser node.
If you have the vive controllers you can run the room setup normally (no need for the HMD to be connected if you use the null driver).
You can also use the tracker as a controller for calibration, but you need to connect a simple circuit to the pogo pins to be able to activate the 'trigger' button during the calibration process.
More detailed developer info on the pogo pins can be found here: Vive Tracker For Developers
You can download the new OpenVR pack here: VVVV.OpenVR
Open the demo patch 02_TrackersOnlyDemo.v4p in the VVVV.OpenVR\girlpower folder and enjoy tracking!
This is awesome! Must mount one of those to a tablet and stream a renderer to it.. Should make for some cool and simple AR applications if latency is okay.
thanks @tonfilm ! this is highly appreciated!
Excellent thanks you, I have one of these and always wanted to test in vvvv.
