Models

Models are given in Stanford Triangle Format (PLY) and Alias Waveform Format (OBJ) - you can use MeshLab or any other tool to convert them to other formats.

Prometheus (Thomas 2018) (PLY 527 KB) (OBJ 1 MB)
Prometheus (Stooke) (PLY 94 KB) (OBJ 165 KB)

Please note that the models are in planetocentric coordinate system, with Z axis passing through north pole. Actual rotational axis may differ from planetocentric poles, especially for small irregular bodies.
