Cartesian path without orientation

edit

Hello!

This is a simple question. Is it possible to execute somehow Cartesian path planning (compute_cartesian_path/computeCartesianPath) without orientation information?

In my application, I have only XYZ positions, and it doesn't matter what is the desired orientation in those positions. Is it possible to omit orientation and pass waypoints array that contain only XYZ data (not Pose, just Position) to compute_cartesian_path/computeCartesianPath function call?

Thank you in advance.

Best regards.
