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.
