Enum TrackableType

Flags that represent trackable types in XR. A trackable is feature in the physical environment that a device is able to track, such as a surface. Often used in conjunction with XRRaycastHit.

Syntax

[Flags]
public enum TrackableType

Fields

Name	Description	Value
AllTypes	Refers to all trackable types.	-1
None	No trackable.	0
PlaneWithinPolygon	Refers to the 2D convex shape associated with a plane's boundary points. When used as the trackableTypeMask in a Raycast(Ray, TrackableType, Allocator), the ray is considered to have hit if the ray intersects with the polygon described by the exact boundary of the plane.	1
PlaneWithinBounds	Refers to the 2D rectangular bounding box that tightly encloses the plane's polygon. When used as the trackableTypeMask in a Raycast(Ray, TrackableType, Allocator), the ray is considered to have hit if the ray intersects with the 2D box described by the size of the plane.	2
PlaneWithinInfinity	Refers to the infinite plane described by its Pose (a position and orientation). When used as the trackableTypeMask in a Raycast(Ray, TrackableType, Allocator), the ray is considered to have hit if the ray intersects with the infinite plane.	4
PlaneEstimated	Refers to an estimated plane. When used as the trackableTypeMask in a Raycast(Ray, TrackableType, Allocator), the ray is considered to have hit if the ray intersects with an estimated plane. An estimated plane is implementation-defined, but might not have an exact boundary. It is a guess that suggests the ray is near a surface.	8
Planes	Refers to any of the plane type trackables. Often used with the trackableTypeMask in a Raycast(Ray, TrackableType, Allocator), the ray is considered to have hit if the ray intersects with any of the plane types.	15
FeaturePoint	Refers to a feature point (that is, a point in a point cloud). When used as the trackableTypeMask in a Raycast(Ray, TrackableType, Allocator), the ray is considered to have hit if a cone around the ray intersects with a point in a point cloud.	16
Image	Refers to a tracked image.	32
Face	Refers to a tracked face.	64
All	Deprecated in favor of AllTypes. Refers to all trackable types except Depth.	127
Depth	Refers to a point in the depth map.	128
