Available sources of automatic depth are: Depth from motion, using the main RGB camera Hardware depth sensor, such as a time-of-flight sensor (or ToF sensor) Provides depth estimation for every pixel in the image, and works best for static scenes. For a list of supported devices, see: https://developers.google.com/ar/devices Adds significant computational load.

Raw depth data is also available when `Automatic` is selected, however `RawDepthOnly` has a lower runtime performance cost. Raw depth is intended to be used in cases that involve understanding of the geometry in the environment.

Available sources of automatic depth are:

Depth from motion, using the main RGB camera

InstantPlacementMode

 InstantPlacementMode

Indicates whether Instant Placement is enabled or disabled.

The default value is InstantPlacementMode.Disabled.

Properties

Properties
`Disabled`	Instant Placement mode is disabled. When Instant Placement is disabled, any `InstantPlacementPoint` having InstantPlacementPointTrackingMethod.`ScreenspaceWithApproximateDistance` tracking method will result in tracking state becoming permanently TrackingState.`Stopped`.
`LocalYUp`	Enable Instant Placement. If the hit test is successful, it will return a single `InstantPlacementPoint` with the +Y pointing upward, against gravity.

The resulting Instant Placement point will always have a pose with +Y pointing upward, against gravity.
No guarantees are made with respect to orientation of +X and +Z. Specifically, a hit test against a vertical surface, such as a wall, will not result in a pose that's in any way aligned to the plane of the wall, other than +Y being up, against gravity.
The InstantPlacementPoint's tracking method may never become InstantPlacementPointTrackingMethod.FullTracking or may take a long time to reach this state.

`ExcessiveMotion`	Excessive movement of the device camera is causing motion tracking to fail.
`InsufficientFeatures`	A lack of visually distinct environmental features in the camera feed is causing motion tracking to fail.
