Typedef Documentation

◆ ArPointCloud

typedef struct ArPointCloud_ ArPointCloud

A cloud of tracked 3D visual feature points (reference type, large data).

Acquire with ArFrame_acquirePointCloud()
Release with ArPointCloud_release()

Function Documentation

◆ ArPointCloud_getData()

void ArPointCloud_getData	(	const ArSession *	session,
		const ArPointCloud *	point_cloud,
		const float **	out_point_cloud_data
	)

Retrieves a pointer to the point cloud data.

Each point is represented by four consecutive values in the array; first the X, Y, Z position coordinates, followed by a confidence value. This is the same format as described in DEPTH_POINT_CLOUD.

The pointer returned by this function is valid until ArPointCloud_release() is called. The application must copy the data if they wish to retain it for longer. The points are in world coordinates consistent with the frame it was obtained from. If the number of points is zero, then the value of *out_point_cloud_data should is undefined.

◆ ArPointCloud_getNumberOfPoints()

void ArPointCloud_getNumberOfPoints	(	const ArSession *	session,
		const ArPointCloud *	point_cloud,
		int32_t *	out_number_of_points
	)

Retrieves the number of points in the point cloud.

◆ ArPointCloud_getTimestamp()

void ArPointCloud_getTimestamp	(	const ArSession *	session,
		const ArPointCloud *	point_cloud,
		int64_t *	out_timestamp_ns
	)

Returns the timestamp in nanoseconds when this point cloud was observed. This timestamp uses the same time base as ArFrame_getTimestamp().

◆ ArPointCloud_release()

void ArPointCloud_release ( ArPointCloud * point_cloud )

Releases a reference to the point cloud. This must match a call to ArFrame_acquirePointCloud().

This method may safely be called with nullptr - it will do nothing.
