Parameters
float x- Supply x as float.
float y- Supply y as float.
float z- Supply z as float.

Notes and source
The example checks the call shape. Opening windows, recording audio, changing files, network operations, and process operations have real effects when run. Follow the corresponding package lifecycle before using live resources.
