## Analytic Surfaces

The 26 meshes under `data/math/` are author-created analytic benchmark
surfaces from the Mesh Untangling project. They are released under the
Apache License 2.0 in `licenses/Analytic-Surfaces-APACHE-2.0.txt`.

## Microsoft Rocketbox

The 140 selected assets under `data/Microsoft-Rocketbox/` are derived from:

The benchmark OBJ files are geometry exports reduced to their largest connected
component; they are not byte-identical copies of the upstream FBX assets.
Companion MTL files are included where present. The canonical OBJ hashes are
recorded in `metadata/included-cases.json`, and hashes for all distributed data
files are recorded in `SHA256SUMS`.

## Excluded benchmark sources

This repository does not distribute geometry from ISIR, SMAL, or SCAPE. Those
datasets must be requested or downloaded from their respective owners under
their own terms.

No Mesh Untangling solver outputs are included in this repository.
