# Sample sources

Files in this directory are loaded by the universal 3D viewer's **Samples**
menu, so people can try each format without uploading anything of their own.
Every sample recorded here is one of:

- a **US government work** (public domain in the United States), mostly the
  NIST MBE PMI test models;
- **public domain** or dedicated to it (CC0 1.0, The Unlicense, Natural Earth);
- **MIT licensed**, with the copyright and permission notice the licence
  requires in [THIRD_PARTY_NOTICES.txt](THIRD_PARTY_NOTICES.txt) and a credit
  in [CREDITS.md](CREDITS.md);
- a file **authored by Innerscene** for the viewer, dedicated CC0-1.0 like the
  rest of the Free Parts Library (the Licence column below reads `CC0-1.0`);
- a file **authored by Innerscene that models one of its own products**
  (Circadian Sky, Virtual Sun), or a CircadianLab render that shows one of
  them in a room: copyright Innerscene Corp, viewable as a sample but not
  downloadable or redistributable (the Licence column below reads
  `Innerscene (restricted, not for redistribution)`).

Where a format is written only by paid software, the sample is a file we wrote
directly to the format's layout (as the viewer's reader documents it), carrying
geometry from one of the sources above. Those rows say so.

Samples under any other licence are not served from here: the menu loads them
from their publisher's own server, listed under
[Loaded from their publishers](#loaded-from-their-publishers) below. Some of
those files also have a copy in this directory because regression tests read
them; the menu does not use it.
