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.
- Lucretia (wrong inertia tensor) (PLY 38 KB) (OBJ 61 KB)
- Lucretia (wrong inertia tensor) (PLY 38 KB) (OBJ 61 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.
