[vtkusers] performance reading large data sets

[Michael Arneson]

Hi 
I am trying to read in a large vtk file (13 million points) using the java
wrapped vtk libraries. 

It takes my program 15 minutes just to load the vtk file but when i load the
data into ParaView, it takes 3 minutes to load and view the file. 

Should I be using a different reader to read in the data? 

Does anyone know what ParaView is using to load the data so quickly (since
ParaView uses vtk) 

I am using the following code to load the file: 

static { 
        vtkNativeLibrary.LoadAllNativeLibraries(); 
} 

... 

vtkGenericDataObjectReader reader = new vtkGenericDataObjectReader(); 
reader.SetFileName("...."); 
reader.Update(); 

Thank you, 
Michael
