def object_manipulator.point_cloud.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
