I found that modifying vtkProbeFilter to make use of a BSP/OctTree
improves performance significantly when large numbers of sample points
are used for probing. I can't remember if I kept the change I made to
probefilter, but if I did, they are in the pv-meshless source tree.<br>

type="cite">Hi all, I'm thinking of writing an interpolation filter
for Paraview in order to transfer data from one 3D grid to another
efficiently using some kind of octree.
<div>Has this already been done ? I have used the Resample with
dataset filter in the past, but this does not give accurate results on
my test cases, also I believe it is not very efficient. </div>
<div><br>
</div>
<div>Any hints about where to start, or classes to look at ? </div>

<div>Cheers,</div>
