CloudCompare is open source software for viewing and manipulating 3D point clouds and meshes. I started participating in the project several years ago to build and package it for macOS and have continued to contribute to it since then.
(The source code for CloudCompare is available on GitHub.)
Last year (2018) I initiated a user survey to get a better idea who is using CloudCompare and to solicit feedback from our users. I set it up using Google Forms and we received 330 responses over the course of about 10 months.
I really intended the survey for internal use to help guide us, but Noemi Roecklinger asked via Twitter about the results so I thought I would put some of them up here in case others are interested.
