Spirit at troy right before getting stuck

I am working at some javascript converters for these old formats; this model is a first result for file https://pds-imaging.jpl.nasa.gov/data/mer/spirit/mer2mw_0xxx/data/navcam/site0137/2mesh_1869_n_137_ffl_0_v2.pfb: This model was created by NASA from images taken right before Spirit got stuck in its sand trap, which should hence be visible in the model (note that rover was moving backwards in its last days). Work based on powerful kaitai-struct library ( https://doc.kaitai.io/user_guide.html ), allowing to create binary structure in one single metalanguage compilable to a dozen of languages (C, javascript, python),... Still working on faces extraction and texture application (format is undocumented). Current KSY definition for PFB file (work in progress) is here: https://github.com/jumpjack/VST-converter/blob/main/PFB.js Inspired by this source code in C++: https://github.com/j3k0/OpenPFB/blob/master/OpenPfb.cpp
