[vtkusers] Help me with vtk file triangle strips

[Randy Dawson]

I'm struggling to find my errors in triangle strips in a vtk ascii file.

 Here is my error message:


ERROR: In C:\Sources\VTK\IO\vtkPolyDataReader.cxx, line 335
vtkPolyDataReader (0x00A704B8): Unrecognized keyword: 24

I have attached one 48 point triangle strip.  Is it critical on floating
point format, spacing, line length, linefeed/cr or ?
This is a cross section of a piece of pipe, a type of well log called a
caliper.  I want to use vtk to analyze the data and wrote a well log
(LAS) to vtk converter, but obviously got something wrong.

Thanks,

Randy Dawson
