XR is a general term used to describe the concept of Extended Reality, which includes Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR).

Architecture

Galacean provides a clean and flexible design for XR:

• Clean: When no XR capabilities are required, the package contains no XR logic, and the size remains unchanged.
• Flexible: Pluggable features simplify development.
• Future-ready: A multi-backend design that can be adapted to different platforms and interfaces in the future.

Module Management

@galacean/engine-xr and @galacean/engine-web-xr are mandatory dependencies for implementing WebXR. In contrast, @galacean/engine-toolkit-xr is not required but simplifies XR development in the editor.

The dependency rules between XR packages follow the version dependency rules:

• The versions of @galacean/engine-xr and @galacean/engine-web-xr must match the version of @galacean/engine.
• The major version of @galacean/engine-toolkit-xr must match that of @galacean/engine.

Quick Start

In this section, you will learn to:

• Quickly develop XR interactions and debug XR interactions without prior expertise.
• For deeper insights into Galacean XR, refer to XR Core Logic.
• Finally, understanding XR Compatibility helps you assess project risks holistically.
