Colored Vesta mosaic was made by combining red, green and blue channels from Thomas Roatch's dataset. Some areas remained black as there were no enough data to render them in full color. I will replace this map with a better one once NASA or ESA produces it.

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.

Vesta (Optical) (PLY 94 KB) (OBJ 171 KB)
Vesta (DAWN) (PLY 457 KB) (OBJ 875 KB)
Vesta (DAWN HAMO, 64k poly) (PLY 1.2 MB) (OBJ 2.3 MB)

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.
