If one wishes to do serious science, that is, needs to know the value and context of the original pixels themselves, join forces with the JPL primary investigators and work with the original data. It was amazing how fast the JPL were able to generate the topographic flybys of Triton shown on TV yesterday. I suppose there canned software at both Pixar and JPL that given a topography, texture, and flyby path can routinely generate a flyby movie. The greater challange is measuring topography. I understand this can be done two ways: (1) comparing multiple views, (2) measuring the size of shadows. I think Triton---The Movie was the latter.
