Gaskell model - Produced by Robert Gaskell, Planetary Science Institute
---
The latest version is produced on Jan. 4 2007.
The model is constructed by applying multi-image photoclinometry. The original data has 3,145,728 facets and 1,579,014 vertices, in a text list of plates and vertices.
The original shape model and smaller models reduced in resolution by three grades are stored in the plate-vertex table format (.txt), the STL ASCII format (.stl), and the triangle format (.tri).
Details of the model was described in Gaskell et al. (2006), AIAA paper 2006_6660, AAS/AIAA Astrodynamics Specialists Conf., Keystone, CO, Aug, 2006.

Notice that you need to get a red/blue(cyan) glasses to see it, with the red over your left eye.

Shape Model data is alomost of all the same data itself but the contents in the directory is different. PDS data directory include label file and detail infromation. Basically, we recommend the PDS data to use.
