Defines an intersection between a ray and estimated real-world geometry.
Public Methods Anchor boolean equals(Object obj)
Indicates whether some other object is a HitResult referencing the same logical hit result as this one.
float getDistance()
Returns the distance from the camera to the hit location, in meters.
Pose getHitPose()
Returns the pose of the intersection between a ray and detected real-world geometry.
Trackable int hashCode()
Returns a hash code value for the object.

public Anchor createAnchor()
Creates a new anchor at the hit location. See getHitPose() for details.
Anchors incur ongoing processing overhead within ARCore. To release unneeded anchors use Anchor.detach().
This method is a convenience alias for hitResult.getTrackable().createAnchor(hitResult.getHitPose())
public boolean equals( Object obj )
Indicates whether some other object is a HitResult referencing the same logical hit result as this one.
obj the reference object with which to compare. Returns true if this object is the same as the obj argument; false otherwise. See Also
public float getDistance () getDistance
public float getDistance()
Returns the distance from the camera to the hit location, in meters.
public Pose getHitPose () getHitPosepublic Pose getHitPose()
Returns the pose of the intersection between a ray and detected real-world geometry. The position is the location in space where the ray intersected the geometry. The orientation is a best effort to face the ray origin, and its exact definition differs depending on the Trackable that was hit.
Plane: X+ is perpendicular to the cast ray and parallel to the plane, Y+ points along the plane normal (up, for Plane.Type.HORIZONTAL_UPWARD_FACING planes), and Z+ is parallel to the plane, pointing roughly toward the ray origin.
Point: Attempt to estimate the normal of the surface centered around the hit test. Surface normal estimation is most likely to succeed on textured surfaces and with camera motion. If Point.getOrientationMode() returns Point.OrientationMode.ESTIMATED_SURFACE_NORMAL, then 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 ray origin. If Point.getOrientationMode() returns Point.OrientationMode.INITIALIZED_TO_IDENTITY, then X+ is perpendicular to the cast ray and points right from the perspective of the ray origin, Y+ points up, and Z+ points roughly toward the ray origin.
If you wish to retain the location of this pose beyond the duration of a single frame, create an Anchor using createAnchor() to save the pose in a physically consistent way.
public Trackable getTrackable()
Returns the Trackable that was hit.
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.
