SRDisplayManager Prefab

SRDisplayManager Prefab is a core prefab of the UnityPugin.

Unity Spatial Reality Display(SR Display) applications needs SRDisplayManager Prefab basically.

  1. Setup your SR Display, if not, see: Setup SR DisplaySetup SR Display Runtime
  2. Set up your Unity project installed SRDisplay UnityPlugin, if not, see: Setup for Unity, Create your simple app "Hello cube!"

GameObject name Description
SRDisplayManager Has SRDManager component that handles SR Display Runtime
└─WatcherAnchor Has no components. This shows the user's head position at runtime.
 ├─WatcherCamera Has a camera component that will be disable at runtime. This is for raycasting from the user, UICamera, or something other than rendering.
 ├─LeftEyeAnchor Has no components. This shows the user's left eye position at runtime.
 │ └─LeftEyeCamera Has a camera component that will render a scene for the user's left eye.
 └─RightEyeAnchor Has no components. This shows the user's right eye position at runtime.
  └─RightEyeCamera Has a camera component that will render a scene for the user's right eye.

There are three cameras: WatcherAnchor, LeftEyeAnchor and RightEyeAnchor

WatcherAnchor, LeftEyeAnchor, and RightEyeAnchor indicate the position of the user's head, left eye, and right eye, respectively.

You can use these anchors for interactions with the user. In SRDisplayLookAtSample sample, WatcherAnchor is used as the target to look at.

Caution

Recognition technology is not always perfect and there are generally some errors. Also, these anchors do not always indicate correct positions of the user's head, left eye, and right eye.

There are three camera components in WatcherCamera, LeftEyeCamera and RightEyeCamera

The camera component in WatcherCamera will be disable at runtime. This should be used for raycasting from the user (e.g. UI camera or something).

If you want to change camera settings(e.g. Clear Flags, Background, etc.), the left and right camera settings MUST be the same for user's comfort.

Also, If you want to add some scripts to camera component, you MUST add them to both LeftEyeCamera and RightEyeCamera. In SRDPostProcessingSampleApp sample, both LeftEyeCamera and RightEyeCamera have Post-process Layer script.

Tips

There is no MainCamera in this prefab. If you need it, we recommend to add MainCamera tag to the camera component in LeftEyeCamera. You should not add MainCamera tag to the camera component in WatcherCamera. This is because WatcherCamera will be disable at runtime automatically to reduce the processing load and you cannot get the component with Camera.main.

SRDManager is a core component that handles SR Display Runtime. And it has fundamental parameters for SR Display that application developers should set.

SRDManager must be only one in the scene at a time.
