Structure

HVR is made of three packages and one side project:

• HVR.Core contains all the Unity components, except the HVRUGC components.
• HVR.UGC only contains HVRUGC components such as the HVRUGC Avatar component, and is intended to be able to be installed separately from HVR if needed.
• HVR.NetworkingPackets contains the packets shared between the client and server.
• HVR.Server is a .NET 10 project that contains the server code.

HVR depends on one package that was previously separated from this project:

• HVR.IK contains the IK solver.

Despite being a package, HVR.Core has many assembly definitions in it, which are described below.

Vendors

Apart from Unity itself, HVR tries to keep vendor dependencies weak so that they may be amputated from the project if necessary.

• VR/XR/Tracking:
  • OpenXRTools creates trackers for OpenXR through the HVR.Tracking module.
  • OpenVROverlayTools creates trackers for OpenVR through the HVR.Tracking module.
  • Trackers created in this way are advertised to HVR.Integration, which then uses them to control the VR camera, calibration, and other tracking facilities.
• Networking:
  • Steamworks raises incoming messages and transmits outbound messages through the HVR.NetworkingPackets module.
