msg: point

simple_msgs - Point

simple_msgs::Point messages represent a 3D position in space: X, Y, Z.

A simple_msgs::PointStamped message is a Point + Header:
the position can then be linked to a reference frame defined by Header.frame_id and its timestamp can be stored in Header.timestamp.

In code:

simple_msgs::Header my_header{0, "root", 1.0};
simple_msgs::Point my_point{1.0, 2.0, 3.0};
simple_msgs::PointStamped my_pointstamped{my_header, my_point}

You can manipulate the PointStamped message using its setters/getters. E.g.

my_pointstamped.getHeader.setTimestamp(2.0);
