[vtkusers] vtk data file format question

[Gala Wind]

Hi everybody,

I have a set of data in an ASCII text file. It's an airplane's flight 
track, so I have lat/long and altitude info and also some onboard 
instrument data. The coords and altitude map nicely into the xyz point 
coordinates. I would like the instrument data to be the scalars for the 
polydata line that gets created. But I have two sets of data and the 
vtk data file format (.vtk) only seems to allow one set of plain 
scalars, can't have scalars with more than one component. I guess I 
could add the second set by hand, but I would like to know if there is 
anything I can do to just put all the data into one vtk datafile, so I 
can just use vtkPolyDataReader to read it all and assemble it correctly.

Thanks for any tips.
