gx:Tour smoothness, interpolation

[Ákos Maróy]

Hi,

I wonder typically what algorithms are used to smooth out a gx:Tour?

I'd like to calculate smooth & frequent position transitions for
gx:Tour files. for example, if I have a gx:Tour kml file, which has
gx:FlyTo elements with 1 second durations, I'd like to have more
frequent position updates (say, once every 0.1 seconds), and if course
a smooth position curve, and also smooth orientation changes.

Is there a 'typical' algorithm / library used to calculate such a
smooth path?
