[vtkusers] some information need for .vtk file version number

[이정규]

Hi Mike,

First of all, thank you for the reply. You are right, those older .VTK file
format can be either ASCII or BINARY. And the thing I'm trying to figure out
is what version number makes the distinction between the newer(XML) file
format and the legacy file format. Let me put it differently. I'm trying to
find the highest version number that can be tagged to a legacy VTK file
format. I've seen 3.0 but not sure what's the difference between 2.0 and
3.0. Is this just literally a number without any semantic that does not
impose any restriction what can be in the file? If so, can I just ignore the
version number?(even if the file says something like "# vtk DataFile Version
65536.0")

Truly yours,
