[vtkusers] Monitor filter

[Jon Haitz Legarreta]

Dear Massi,
does the standard output show anything? i.e. A rounded output, zero?

In theory, for a floating point number, if you do not set the precision
[1], std::cout will round/limit the precision of the output to be displayed.

If you don't assume that the rest of your program is right, you can try
storing the mean distance value in a variable and then see whether it
actually contains some "expected" value.

HTH,
JON HAITZ
