Cloud2 – GUI

Cloud2 is a powerful tool for processing different types of data. Cloud (to) can transform, process, and evaluate data such as point clouds, vector fields, space curves, and meshes. In addition, it has a powerful renderer that allows stunning graphics (see slideshow).

Version 19.8.26

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)”.
