public class
Point
Represents a point in space that ARCore is tracking. These objects are created as a side-effect
of Session.createAnchor(Pose) or when Frame.hitTest(float, float) returns results
against a point cloud.
Note: Two Point objects may refer to the same logical point managed by ARCore. Be sure
to always use equals(Object) when comparing them.

Public Methods
public Anchor createAnchor (Pose pose)
createAnchor
public Anchor createAnchor( Pose pose )
Creates an anchor that is attached to this trackable, using the given initial pose in the world coordinate space. The type of trackable will determine the semantics of attachment and how the anchor's pose will be updated to maintain this relationship. Note that the relative offset between the pose of multiple anchors attached to a trackable may adjust slightly over time as ARCore updates its model of the world.

|---|---|
| Returns | Point.OrientationMode

public Pose getPose ()
getPose
public Pose getPose()
Returns the pose of the point for Points created by Frame.hitTest(float, float).
- If
Point.OrientationModeisPoint.OrientationMode.ESTIMATED_SURFACE_NORMAL, then the orientation is such that X+ is perpendicular to the cast ray and parallel to the physical surface centered around the hit test, Y+ points along the estimated surface normal, and Z+ points roughly toward the user's device. - If
Point.OrientationModeisPoint.OrientationMode.ESTIMATED_SURFACE_NORMAL, then the orientation is identity or close to identity.

hashCode
public int hashCode()
Returns a hash code value for the object. This method is supported for the benefit of hash
tables such as those provided by HashMap.
