简介

AR Foundation Overview

  • Core Functionality: AR Foundation allows developers to create multiplatform augmented reality applications in Unity by providing a unified interface for native AR SDKs.
  • Architecture: The package acts as an abstraction layer; it does not implement features itself but requires specific provider plug-ins to function on target platforms.
  • Required Plug-ins:
    • Android: Google ARCore XR Plug-in
    • iOS: Apple ARKit XR Plug-in
    • visionOS: Apple visionOS XR Plug-in
    • HoloLens 2 / Meta Quest: OpenXR Plug-in
  • Key Supported Features:
    • Tracking: Device, Plane, Bounding Box, Image, Object, Face, Body, and Point clouds.
    • Interaction: Ray casting, Anchors, and Participants (shared sessions).
    • Environment: Meshing, Environment probes, and Occlusion.
    • System: Session management and Camera/Light estimation.
  • Development Notes:
    • Feature availability varies by platform; developers must check the compatibility matrix before implementation.
    • XR Simulation is available to test specific AR features directly within the Unity Editor.
    • The "Simple AR" sample scene is recommended for beginners to learn plane detection and raycasting.
