How To Videos

Constellation Maker Ver 0.3


Create your own Walker constellations in this Octave script set. You enter the number of constellations, orbital parameters, phasing angle, and ground stations. The script generates the xml scene file which you can then load in PIGI from main menu bar.

CAD Importer Ver 0.2


Get your own spacecraft into PIGI!  Convert from 3D printer .stl files to PIGI format.  Written in Python the scripts use Blender (see Blender.org) to set up both the low resolution overview spacecraft and a higher resolution for the coveted exploded view.
