FlexXR: UI Toolkit in World Space and Mixed Reality

FlexXR is a general solution to extend Unity's UI Toolkit (a.k.a. UI Elements) with support for

  • world space rendering and interaction, and
  • mixed reality interaction via XR Interaction Toolkit.

FlexXR was originally conceived as a solution for our company's own flagship product, LiquidEarth, where we use the same UI Elements GUI across desktop, mobile, and mixed reality platforms.
