Threshold filter lowers precision of Points data
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
How to reproduce:
1.) Open a file that stores positions in double precision. 2.) Apply Threshold filter 3.) Look at point data in spreadsheet view
Before the point data in spreadsheet view was double precision, after applying the filter the point data is only in single precision.
I'm not a 100% sure but can this be related to line 40 in VTK/Graphics/vtkThreshold.cxx which reads this->PointsDataType = VTK_FLOAT;
