Introduction - If you have any usage issues, please Google them yourself
This gridlib collection has arisen decades of application programming
at NASA Ames Research Center involving (mostly) structured grids in 2- and
3-space, including many utilities for generating grid point distributions
along a line or curve. Of these, curvature-based and (extremely precise)
Vinokur-type distributions are most valuable. See program DISTRIBUTE for
driving such utilities. Transfinite interpolation, elliptic smoothing, and
grid perturbations are also supported here.
