Valles Marinaris

Original creator description

A small (~80mmx80mm) print of the Valles Marinaris region on Mars. You can make your own (if you aren't afraid of the terminal) by using png23d and freeware like MeshLab. png23d takes a greyscale image (like the one I posted, which shows actual topographic data from the MOLA instrument) and assigns different heights based on the pixel greyscale value. Porting the resultant solid to MeshLab allows you to reduce the number of facets to something more reasonable (like 100,000). I'm still working on the process in my spare time and haven't quite worked out the bugs... I didn't generate this stl - I found it at this site: http://nasa3d.arc.nasa.gov/detail/valles-marineris From the nasa website:... This hosted file keeps creator credit and license details.
