Typedef Documentation

◆ ArPoint

typedef struct ArPoint_ ArPoint

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

Function Documentation

◆ AR_DEFINE_ENUM()

AR_DEFINE_ENUM ( ArPointOrientationMode )

Indicates the orientation mode of the ArPoint.

The orientation of the ArPoint is initialized to identity but may adjust slightly over time.

The orientation of the ArPoint will follow the behavior described in ArHitResult_getHitPose().

Definition at line 761 of file arcore_c_api.h.

                                      {
    /// The orientation of the ::ArPoint is initialized to identity but may
    /// adjust slightly over time.
    AR_POINT_ORIENTATION_INITIALIZED_TO_IDENTITY = 0,
    /// The orientation of the ::ArPoint will follow the behavior described in
    /// ArHitResult_getHitPose().
    AR_POINT_ORIENTATION_ESTIMATED_SURFACE_NORMAL = 1};

◆ ArPoint_getOrientationMode()

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

Returns the OrientationMode of the point. For Point objects created by ArFrame_hitTest(). If OrientationMode is ESTIMATED_SURFACE_NORMAL, then normal of the surface centered around the ArPoint was estimated succesfully.

Parameters

[in]	session	The ARCore session.
[in]	point	The point to retrieve the pose of.
[in,out]	out_orientation_mode	OrientationMode output result for the the point.

◆ ArPoint_getPose()

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

Returns the pose of the point. If ArPoint_getOrientationMode() returns ESTIMATED_SURFACE_NORMAL, the orientation will follow the behavior described in ArHitResult_getHitPose(). If ArPoint_getOrientationMode() returns INITIALIZED_TO_IDENTITY, then returns an orientation that is identity or close to identity.
