Scattered data interpolation files

For scattered data interpolation, there are two input files and one output file.

The point input file also contains the data for each vertex. This file has the following format (written as a pseudo-template file).

  nverts ndata_per_vert

  verts: coords data1 data2 ...

The input file of target points is even simpler:

  nverts

  verts: coords

The output file is also quite simple:

  verts: coords new_data1 new_data2 ...
