UVRPN - VRPN wrapper for Unity3D

You can build the plugin from scratch, or use the download in the releases, or use the Unity package in the releases which includes built plugins for Windows, OS X, Linux, and Android.

Recently tested with an ART DTrack device under Windows 64bit and Unity 2017.2.

Features

Easy integration of multiple VRPN tracking devices
Supports Trackers, Buttons and Analog data
No external application or heavy-weight framework needed
Nice interface with custom editors

Getting Started

Download and import the latest release.
Add a VRPN_Manager component to any object in the scene.

Reference

public static double Analog(string address, int channel)

This gets an analog value from the vrpn address and the channel. When first called with a new address, the vrpn connection will be created. An address's values will be updated at most once per frame.

public static bool Button(string address, int channel)

This gets a boolean value from the vrpn address and the channel. When first called with a new address, the vrpn connection will be created. An address's values will be updated at most once per frame.

public static Vector3 TrackerPos(string address, int channel)

This gets position component of a tracker at the vrpn address and the channel. When first called with a new address, the vrpn connection will be created. An address's values will be updated at most once per frame.

public static Quaternion TrackerQuat(string address, int channel)

This gets rotation component of a tracker at the /vrpn address and the channel. When first called with a new address, the vrpn connection will be created. An address's values will be updated at most once per frame.
