XR Origin は、XR シーンのトラッキング空間の中心として機能します。
An XR Origin configuration is a set of GameObjects and components that work together to transform data from the XR tracking subsystems into world space. For example, the TrackedPoseDriver component on the Main Camera GameObject moves the Camera relative to the XR Origin using the tracking data for the user’s headset or handheld device. See XR Origin for more information about the XR Origin.
XR devices provide tracking data in real-world units relative to a point chosen by the XR system at initialization. Unity aligns the XR Origin GameObject in a scene with this initial point. The starting position of the XR Origin in the scene also determines the default starting position of the Camera.
ユーザーのヘッドセットやハンドヘルドデバイスなどの、トラッキングされたエンティティを表すゲームオブジェクトは、シーン階層内では XR Origin ゲームオブジェクトの子です。つまり、トラッキングの更新に基づく位置や角度の変化は、XR Origin を基準とした相対的なものです。こうした子ゲームオブジェクトは、ユーザーが現実世界で動くと、シーン内で XR Origin に対して相対的に動きます。XR Origin はそれ自体で勝手に動くことはありません。ただし、スクリプトを使って XR Origin を動かして、ユーザーがテレポートしたりコントローラー入力で移動したりできるようにすることは可能です。
The Unity XR packages provide a number of XR Origin configurations tailored for different types of XR applications. The available options depend on which packages you have added to your project.
XR のタイプ | リグ | メニュー | パッケージ | ノート |
---|---|---|---|---|
VR、MR | XR Rig | GameObject > XR > Convert Main Camera To XR Rig | XR Legacy Input Helpers (installed with the XR Plug-in Management package) | Replaces the standard Camera in a basic Unity Scene. The logic used to replace the main camera can fail in complex scenes. |
VR、MR | XR Origin | GameObject > XR > XR Origin | XR Core Utils (installed with the XR Interaction Toolkit package) | コントローラー用のゲームオブジェクトは含まれません。 |
VR、MR | XR Origin (VR) | GameObject > XR > XR Origin (VR) | XR Interaction Toolkit | アクションベースの入力用に設定されたコントローラーゲームオブジェクトが含まれます。 |
VR、MR | XR Origin (VR) | GameObject > XR > Device-based > XR Origin (VR) | XR Interaction Toolkit | デバイスベースの入力用に設定されたコントローラーゲームオブジェクトが含まれます。 |
AR | XR Origin (AR) | GameObject > XR > XR Origin (AR) | XR Interaction Toolkit | Includes controller GameObjects. |
AR | AR Session Origin | GameObject > XR > AR Session Origin | AR Foundation | Deprecated in favor of XR Origin (AR). |
Note: In the latest versions of the Unity XR packages, the XR Rig have been renamed to XR Origin. The XROrigin
component also replaces the CameraOffset
component, providing a few additional settings. See XR Origin component for more information. In addition, the AR Session Origin has been renamed to XR Origin (AR).
