ArPoint

Represents a point in space that ARCore is tracking.

Summary

Enumerations
`ArPointOrientationMode{ AR_POINT_ORIENTATION_INITIALIZED_TO_IDENTITY = 0, AR_POINT_ORIENTATION_ESTIMATED_SURFACE_NORMAL = 1 }`	enum Indicates the orientation mode of the `ArPoint`.

Typedefs
`ArPoint`	typedef `struct ArPoint_` An arbitrary point in space (reference type, long-lived).

Functions
`ArPoint_getOrientationMode(const ArSession session, const ArPoint point, ArPointOrientationMode *out_orientation_mode)`	`void` Returns the `ArPointOrientationMode` of the point.
`ArPoint_getPose(const ArSession session, const ArPoint point, ArPose *out_pose)`	`void` Returns the pose of the point.

 ArPointOrientationMode

Indicates the orientation mode of the ArPoint.

Properties
`AR_POINT_ORIENTATION_ESTIMATED_SURFACE_NORMAL`	The orientation of the `ArPoint` will follow the behavior described in `ArHitResult_getHitPose`.
`AR_POINT_ORIENTATION_INITIALIZED_TO_IDENTITY`	The orientation of the `ArPoint` is initialized to identity but may adjust slightly over time.

struct ArPoint_ ArPoint

An arbitrary point in space (reference type, long-lived).

void ArPoint_getOrientationMode(
  const ArSession *session,
  const ArPoint *point,
  ArPointOrientationMode *out_orientation_mode
)

Returns the ArPointOrientationMode of the point.

For ArPoint objects created by ArFrame_hitTest. If ArPointOrientationMode is AR_POINT_ORIENTATION_ESTIMATED_SURFACE_NORMAL, then normal of the surface centered around the ArPoint was estimated successfully.

Details

Parameters

`session`	The ARCore session.
`point`	The point to retrieve the pose of.
`out_orientation_mode`	OrientationMode output result for the point.

void ArPoint_getPose(
  const ArSession *session,
  const ArPoint *point,
  ArPose *out_pose
)

Returns the pose of the point.

Details

Parameters

`session`	The ARCore session.
`point`	The point to retrieve the pose of.
`out_pose`	An already-allocated `ArPose` object into which the pose will be stored.
