Hi Leon,

I believe we used to have support for "weighted N nearest neighbors" interpolation somewhere -- we'll try to track down and resuscitate that code.

Cheers,
Dave

Hi,

I am trying to interpolate a potential field, from data measured from 83
electrodes in a section of cardiac tissue, onto a mesh with about 10201 nodes.

I prepared a ".pts" file containing the electrode positions, then use the
"TextToPointClouldField" converter. And for the 83 potential
measurements, I used the converter "TextToColumnMatrix".
I then used the "ManageFieldData" module to combine the data. Then with
this combined data, and the mesh, I used the "DirectMapping" module.
But when I displayed the resulting field, it appeared too coarse (a
pattern of squares).
How could I make the interpolation more smoother?
