This model was rendered using MATLAB R2016a on topographic map from Schenk
(2008), made with the images from the Voyager mission. When the Voyager 2 probe flew by Triton, tooks very few pictures of it. Less than a half of its surface is known, so the topography that can be deduced from photometry is reduced to a little patch. The rest was filled by interpolation with many randomly distributed points of the same mean radius height.
The file's names explained: name_1_x_10_y.stl is 1 : x * 10y. So _1_6_10_7 is 1:600000000 or one in 60 million.

Triton is the biggest known irregular satellite, the biggest moon of Neptune, and the biggest compared with its parent planet of the gas planets. Irregular moons have high inclined, high eccentric (not in the case of Triton) and retrograde orbit. They are thought to have been captured by its planet. In the case of Triton, it is thought it was a TNO (trans Neptune object) because of the similar composition with them. If that was the case, it had the sufficient mass and size to be a dwarft planet. It is bigger than Pluto and Eris. The moon's capture also helped to deplete the neptunian system of medium sized moons by collision or gravitational interaction with them.
