[scripting] finding source vertex of a hair strand

[Greg Smith <greg(at)stanwinston.com>]

I'm running into a little bit of a problem with hair. I've been trying
to figure out what is the best way to find what vertex a hair strand is
emitted from, since there doesn't seem to be a straight forward approach
in the first place. What has worked for me up to this point is using the
GetClosestLocations method from the hair emitter object, using the
position data from the first point on each strand of hair. this work if
your hair is projecting out perfectly perpendicular. However, in cases
where the hair is styled and the first point of the hair strand resides
closer to a neighboring vertex on the emission object, the method does
not return the desired positional data.
So I am curious is there indeed a way to fetch which vertex a hair
strand is emitted from regardless of how that hair has been styled.

Thanks, 

Greg
