3D worlds

There are a number of third-party 3D world platforms that provide multi-user social experiences in shared virtual spaces. You can chat with other players, move between rooms through portals, and even build complex interactions and games without having to be an expert. For examples of 3D virtual worlds, check out the following:

• VRChat: http://vrchat.net/
• AltspaceVR: http://altvr.com/
• High Fidelity: https://highfidelity.com/

While these platforms may have their own tools for building rooms and interactions, in particular, VRChat lets you develop 3D spaces and avatars in Unity. Then you export them using their SDK and load them into VRChat for you and others to share the virtual spaces you created over the internet in a real-time social VR experience. We will explore this in Chapter 13, Social VR Metaverse.
