Dear<br><br>I just try to make some new classes and want the class to use in python.<br><br>It seems that current vtk do not have class related to sorting or calculate standard deviation or distance between vtkPoints or standard deviation etc.
<br><br>My question is "should I develp these classes under which directory?<br>I tried to put under hybrid or filter but there occurs errors like follows: my class name is vtkStatistics<br><br>Creating library D:\PROJECT\VTK\bin\Debug/vtkFiltering.lib and object D:\PROJECT\VTK\bin\Debug/vtkFiltering.exp
<br>vtkFilteringInstantiator.obj : error LNK2001: unresolved external symbol "class vtkObject * __cdecl vtkInstantiatorvtkStatisticsNew(void)" (?vtkInstantiatorvtkStatisticsNew@@YAPAVvtkObject@@XZ)<br>D:\PROJECT\VTK\bin\Debug/vtkFiltering.dll : fatal error LNK1120: 1 unresolved externals
<br>Error executing link.exe.<br><br clear="all">Thanks in advance<br>
