OpenXR fundamentals

A project where I followed a tutorial to get a better understanding of how to implement AR/VR into my own projects.

The artifacts visible in this video are not visible in the actual application.

For one of my self-study projects during school, I learned about the OpenXR standard for VR/AR devices and how to implement it for my projects. To do this, I followed the tutorial created by the Kronos group. This tutorial provides a broad overview of the different methods for interacting with VR/AR devices and how to create applications for them. By the end of the tutorial, I created a VR application where the player can move around boxes that represent a floor and a table. Above the table, some cubes can be picked up and moved by the player. There are also cubes where the player’s hands are in the real world.

What did I learn?

The tutorial I followed covered the following:

• Setting up the OpenXR instance and session
• Setting up session event handling
• Setting up rendering buffers for OpenXR
• Setting up rendering for OpenXR
• Setting up Input actions for OpenXR
• Receiving inputs through defined actions (button presses, controller position)
• Providing input through defined actions (controller rumble)
• Adding API layers for debugging
• Adding extensions for extending the API functionality (hand tracking)
• Retrieving function pointers for extension functions
