R help - Nov 2008 - 3D trajectory plot?

Hello,
I'm attempting to create a smooth, 3D plot of a trajectory (rather
than the cloud or wireframe functions).  I would rather the individual
data points not be visible.  I've had no luck finding this on the
graphics or help pages.  Thank you in advance.  Chris
Some example data, just in case:

25	32	40
12	25	32
2	12	25
2	2	12
20	2	2
1	20	2
6	1	20
5	6	1
5	5	6

Are you talking about a 'streamline' like might be made with
'vtk'? or in a number of fluid dynamics, groundwater packages, particle
physics codes, etc.? There was an exploratory hook up of R and vtk by M. Kondrin
a year or two back (linux only). Search the archives. Parsing a vtk dataset in R
should relatively straight-forward.
