Detailed Description

This is semantically different than a point. A vector is always anchored at the origin. When a transform is applied to a vector, only the rotational component is applied.

Vector3Publisher publishes vector3 values to a ROS 2 topic. Set the topic and node properties, then call publish() to send messages.

See also Vector3Subscriber and vector3.
