Solar System models
« dnia: 20140916, 15:37:52 »
I've discovered an archive of shape models created from NASA and ESA spacecraft photography:

The models are in ICQ format which cannot be directly imported into Blender. However, I contacted Robert Gaskell and he provided a Fortran file to convert the ICQ file to Blender-readable STL format. I am attaching the Fortran file. I have not yet compiled the Fortran code. Perhaps someone can see how it works?

I also contacted Holger Sierks, the principal investigator of the OSIRIS camera on the Rosetta spacecraft. He provided a low-res OBJ model of comet 67/P Churyumov-Gerasimenko. I am attaching it, but it does not show very much detail. I hope to receive a higher-res model based on closer photography. I will post it once I receive it.

If you use the OBJ file for the comet in any animations or imagery for the public, please use the following credit:

  OSIRIS was built by a consortium led by the Max-Planck-Institut für
Sonnensystemforschung, Göttingen, Germany, in collaboration with CISAS,
University of Padova, Italy, the Laboratoire d'Astrophysique de Marseille,
France, the Instituto de Astrofísica de Andalucia, CSIC, Granada, Spain, the
Scientific Support Office of the European Space Agency, Noordwijk, The
Netherlands, the Instituto Nacional de Técnica Aeroespacial, Madrid, Spain,
the Universidad Politéchnica de Madrid, Spain, the Department of Physics and
Astronomy of Uppsala University, Sweden, and the Institut  für Datentechnik
und Kommunikationsnetze der Technischen Universität  Braunschweig,
 The support of the national funding agencies of Germany (DLR), France
(CNES), Italy (ASI), Spain (MEC), Sweden (SNSB), and the ESA Technical
Directorate is gratefully acknowledged.
 We thank the Rosetta Science Ground Segment at ESAC, the Rosetta
Mission Operations Centre at ESOC and the Rosetta Project at ESTEC for their
outstanding work enabling the science return of the Rosetta Mission.

Hi Kevin, recently I had only barely some time to look at the forum. It seems that script you've attached is very interesting, and I think it can be simply translated to something more understandable by our younger friends here. Dunno if I'll have some time for that, but definitely the livear algebra which is used in this fortran code is very basic and there should be no problem to port it even to python directly for blender. I suspect that there are some packages for python which already have distance or vector operations implemented.

By the way, it's nice to see something production oriented in fortran, long years have been passed when I saw something like this :) But then, my fortran was in 77 version, which is still in the use in many places around the world.
