Cloud2 – GUI

A powerful tool to process data files. Cloud (to) can transform, process and evaluate data such as point clouds, vector fields, space curves and meshes.

Version 12.6.9

This program is owned by Heiko Stark. It can be used free of charge for non-commercial use. For the common citations in publications please use the following entry “Cloud2 software (Heiko Stark, Jena, Germany, URL: https://starkrats.de).
