def sensor_msgs.point_cloud2.create_cloud	(		header,
			fields,
			points
	)

Create a L{sensor_msgs.msg.PointCloud2} message.

@param header: The point cloud header.
@type  header: L{std_msgs.msg.Header}
@param fields: The point cloud fields.
@type  fields: iterable of L{sensor_msgs.msg.PointField}
@param points: The point cloud points.
@type  points: list of iterables, i.e. one iterable for each point, with the
               elements of each iterable being the values of the fields for 
               that point (in the same order as the fields parameter)
@return: The point cloud.
@rtype:  L{sensor_msgs.msg.PointCloud2}

def sensor_msgs.point_cloud2.create_cloud_xyz32	(		header,
			points
	)

Create a L{sensor_msgs.msg.PointCloud2} message with 3 float32 fields (x, y, z).

@param header: The point cloud header.
@type  header: L{std_msgs.msg.Header}
@param points: The point cloud points.
@type  points: iterable
@return: The point cloud.
@rtype:  L{sensor_msgs.msg.PointCloud2}

def sensor_msgs.point_cloud2.read_points	(		cloud,
			field_names = None,
			skip_nans = False,
			uvs = []
	)

Read points from a L{sensor_msgs.PointCloud2} message.

@param cloud: The point cloud to read from.
@type  cloud: L{sensor_msgs.PointCloud2}
@param field_names: The names of fields to read. If None, read all fields. [default: None]
@type  field_names: iterable
@param skip_nans: If True, then don't return any point with a NaN value.
@type  skip_nans: bool [default: False]
@param uvs: If specified, then only return the points at the given coordinates. [default: empty list]
@type  uvs: iterable
@return: Generator which yields a list of values for each point.
@rtype:  generator

def sensor_msgs.point_cloud2.read_points_list	(		cloud,
			field_names = None,
			skip_nans = False,
			uvs = []
	)

Read points from a L{sensor_msgs.PointCloud2} message. This function returns a list of namedtuples. 
It operates on top of the read_points method. For more efficient access use read_points directly. 
 
@param cloud: The point cloud to read from.
@type  cloud: L{sensor_msgs.PointCloud2}
@param field_names: The names of fields to read. If None, read all fields. [default: None]
@type  field_names: iterable
@param skip_nans: If True, then don't return any point with a NaN value.
@type  skip_nans: bool [default: False]
@param uvs: If specified, then only return the points at the given coordinates. [default: empty list]
@type  uvs: iterable
@return: List of namedtuples containing the values for each point
@rtype: list
