How to access SteamVR base station location or room size data?

SteamVR tracking APIs are not a part of Varjo SDK. Use Valve's OpenVR API to request the data. 

OpenVR and its documentation is available here:  

  1. Add OpenVR DLL to your project.
  2. Initialize OpenVR session.
  3. Request the data you need.

For base station locations refer to: ETrackedDeviceClass.TrackedDeviceClass_TrackingReference For room size refer to: GetPlayArea
