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.
- Sillanpaa (Model 1) (PLY 38 KB) (OBJ 60 KB)
- Sillanpaa (Model 2) (PLY 36 KB) (OBJ 57 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.
