This example shows how one goes from randomly spaced data points to an evenly sampled \ref d_surf "surface".

We have 13504 interpolation points (file examples/surfit/points/points.txt) and equidistant grid with more than 250000 nodes. To produce interpolation evenly sampled surface we do the following things:

points, points_add, completer

Here is the image of the resulting surface:

This result was obtained with "examples/surfit/points/points_exact.tcl" script.
