Message from OpenXR Chair
" The OpenXR specification is a crucial part of the Mixed Reality ecosystem. Where previously application developers had to develop for each XR headset separately using proprietary APIs, they now have the freedom to develop for many different devices at once. With OpenXR, applications can be quickly retargeted to new platforms, or even run on new platforms unmodified. This lowers the cost of entry and unlocks the door to bringing in the new developers and ideas that will help make Mixed Reality a common part of our lives "
Ron Bessems — OpenXR Working Group Chair and Distinguished Software Engineer at Magic Leap
What is OpenXR
Solving XR Fragmentation
Before OpenXR, developers needed to create separate proprietary code paths to support all the different devices on the market. With OpenXR, developers now have access to a single high-performance cross-platform API that enables them to build a solution once, then easily port and optimize it to reach more customers, while still taking advantage of the innovative features of specific platforms through OpenXR extensions and API layers.
OpenXR standardizes the use of a range of cross-platform XR device capabilities, including:
- Head Mounted Displays
- Controllers
- Base Stations
- Trackers: Body, hand, object, eye, etc.
- Haptic Devices
- Game Engines
- Cloud/5G Infrastructure
- And more ...
OpenXR for Programmers
To the application programmer, OpenXR is a set of functions that interface with a runtime to perform commonly required operations such as accessing controller/peripheral state, getting current and/or predicted tracking positions, and submitting rendered frames.
A typical OpenXR program begins with a call to create an instance which establishes a connection to a runtime. Then a call is made to create a system which selects for use a physical display and a subset of input, tracking, and graphics devices. Subsequently, a call is made to create buffers into which the application will render one or more views using the appropriate graphics APIs for the platform. Finally, calls are made to create a session and begin the application’s XR rendering loop.
OpenXR for Runtime Implementors
To the runtime implementor, OpenXR is a set of functions that control the operation of the XR system and establishes the lifecycle of a XR application. The implementor’s task is to provide a software library on the host which implements the OpenXR API, while mapping the work for each OpenXR function to the capabilities of the underlying device.
