This example shows how one goes from randomly spaced data points to an evenly sampled surface. We have 13504 approximation points (file
examples/surfit/points/points.txt) and equidistant grid with more than 250000 nodes. To approximate points to evenly sampled smooth surface we do the following things:
Here is the image of the resulting surface:
Pic 1. approximation surface
Pic 2. small part of approximation surface
This result was obtained with
