Limitations

- OS support:

The VTK plugin has been implemented and tested for Windows only. Support for Linux, MacOS and Android might come in future versions.

- Unity Graphics API:

VTK relies on the OpenGL rendering backend, thus Unity graphics API must be set to OpenGLCore.

- Virtual and Augmented Reality:

Although VTK and ActiViz natively support rendering in VR and AR headsets such as the Hololens 2, the Unity support for OpenXR does not work with the OpenGLCore rendering backend. For this reason, the plugin only supports rendering in VR headsets using the Unity legacy VR support that is based on OpenVR and available in Unity 2019.

- Missing features:

This asset provides a small subset of the VTK features available in C++. It is possible to access the whole set of features offered by VTK by using the VTKUnity-Activiz paid asset. Please contact kitware@kitware.fr for details or troubleshooting.
