This model and terrain maps are based on data transmitted by NASA's New Horizon spacecraft during its flyby through Pluto system in 2015. Some of the terrain (south of about 30°S and the Western hemisphere) was in darkness leading up to and during the flyby, so there is no much data about it.
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.
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.
Textures are simple cylindrical projections with prime meridian at the middle, provided at the highest resolution available.
