[Paraview] what is pkdtree, and why is it so slow?

[Moreland, Kenneth]

Are you running in parallel?  And do you have the opacity set to less
than 1?  In order to render correctly in this case, ParaView
redistributes the surface data on the server.  vtkPKdTree is used in
that process.  If you set the opacity to 1, then you should not have to
wait.

hi,

i have a vtk file loaded into paraview3, and i have made an
isosurface rendering.  when i want to select the vtk object
in the pipeline browser (because, for example, i want to try
and draw another surface with a different isovalue), i see 
this pkdtree thing show up in the progress bar, and it takes
a long time (10s of seconds) just to reset all the controls
(object inspector, etc) to reflect that i have selected the vtk
source rather than the contour.
