Hi Susanna,
If your data can be arranged as a grid, even one not at regular
intervals (as long as each grid box is convex), then you can use a
GriddedSet instead for greater performance.
If your samples are truly irregular, you can use IrregularSet--it
implicitly computes a Delaunay triangulation of your samples and
uses it to display them as a surface. Test29 demonstrates this.
