0. AR Toolkit

This toolkit hopefully lays some groundwork for when we need to work on AR projects. It features a few AR basics and a more robust guide on AR Multiplayer.

All of the work here is done in Augmented Reality using Unity and AR Foundation 5. The multiplayer sketches additionally use Photon PUN 2¹.

Code

Additional Knowledge:

AR Multiplayer Basics

1. Initialisation
2. Ownership
3. Syncronisation
4. Colocalisation

Context:

This work is built as a part of the 0. Extended Realities branch of R&D 2024.

It is meant to complement work (prototypes and proof of concepts) built in mixed reality. For e.g., the drawing example (AR Drawing) is a direct synthesis of a proof of concept in MR using shared spatial anchors.
