A Unity3D plugin for Phantom Omni and 3DS Touch/TouchX written in C/C++

Tested With:

  • Sensable Phantom OmniSensable Phantom Omni (IEEE 1394 Interface)
  • 3D Systems Touch3DSystems Touch

Currently Only supports Windows though it should be straightforward to port it to GNU/Linux.

This is a wrapper for OpenHaptics geared towards Unity3D. This plugin is under development.


  • Sphere rendering
  • Gravity well rendering

Build requirements:

  • Cmake (unless you want to make a project manually)
  • OpenHaptics by 3DS (which, ironically, is closed source). The build system will try to locate the header and library files under $(OH_SDK_BASE) Environment variable in Windows.
  • (Optional) Set Environment Variable Unity_Plugins_Folder and uncomment the bottom of CMakeLists.txt to make the build system automatically copy the built library to your Assets/Plugins folder.

To use in Unity 3D:

  • Copy the built plugin to your Assets/Plugins folder (or make the build system automatically do it for you - see CMakelists.txt)
  • Create a new c# script that inherits from :Haptic
  • Implement OnStylusButtonDown method
  • (Optional) use stopCallback and startSphereCallback(...) to add a sphere and test your haptic device.
  • Press Play


  • Both the haptic plugin source and the Unity3D haptic class source are self-explanatory.
  • Due to Unity3D/Mono limitations, if you make changes to the C/C++ library you must completely close and restart unity to load the new build of the .dll.
  • Feel free to open an issue with feature requests
