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.
- Geographos (LightCurve) (PLY 38 KB) (OBJ 61 KB)
- Geographos (Radar-based, low-res) (PLY 77 KB) (OBJ 127 KB)
- Geographos (Radar-based, mid-res) (PLY 305 KB) (OBJ 532 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.
