[Paraview] loading

[Jon Johansson]

Hi,

I have a set of polydata that I would like to load into ParaView.
My problem is that it's taking way to long to load and it seems 
to be spending most of its time in the Quadric Clustering filter.
The data set looks like this:

   # vtk DataFile Version 2.0
   IBD stuff
   ASCII
   DATASET POLYDATA
   POINTS 1180014 float
   5.999289e+002  1.174816e+003  1.198756e+003  
   5.999289e+002  1.174989e+003  1.196801e+003  
   5.999289e+002  1.174927e+003  1.202675e+003  
   ...

There are over a million points each with a single scalar value
associated. 

When I cut the data set down to 10,000 points it takes 30 sec
to load and if I use 100,000 points it loads in 1900 secs. Most 
of the time the progress bar is indicating that the Quadric
Clustering filter is working hard. I've never used it and I'd
_really_ like to turn that filter off but I can't find a way to do
that in the interface - it seems to be default behaviour on loading
this data set.

I'm not experienced with ParaView at all (just downloaded it
yesterday), but this data set loads in both VTK and MayaVi in a
small number of seconds.

I'm using the latest binary of ParaView 1.8 on WinXP.

Is there a way that I can change the behaviour of the loader
so that the Quadric Clustering filter isn't called?

Thank you,
Jon.
