Interpolate a given scalar volume adding points between original grid points. The interpolation is done using a tricubic polynomial.
|volume_in||Field||A field with scalar node data. This field should be at least 4x4x4.|
|Points added||slider||Points to be added between original grid points. If zero, the input volume is simply copied to output.|
|volume_out||Mesh+Node_Data||The interpolated volume.|
