GRANDTOUR creates accurate wireframe scenes from Voyager or Giotto spacecraft, and from space or Earth (spacecraft visible). User has considerable control over time, field, etc., and many frames/second are generated. Developed at JPL to assist in analysis of science and optical navigation data, it was also filmed by the BBC/NOVA for a Voyager documentary. Conveniently runs from any Windows/DOS.
