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.

Antigone (Torppa) (PLY 39 KB) (OBJ 64 KB)
Antigone (Hanuš) (PLY 16 KB) (OBJ 35 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.
