Interface Summary

Interface	Description
AccumulativeGridSampler.AccumulativeMetric<TZ>	An accumulative metric give the behavior of combining several samples to a regular sample grid, ie how we should weight and add several TZ values from inside a cell to compute the cell corner TZ values.
DelaunayTriangulation<TZ>	A Delaunay triangulation (adapted to isoline building).
IsolineBuilder<TZ>	Generic interface for a class that compute an isoline out of a TZ 2D "field".
IsolineBuilder.ZMetric<TZ>	A ZMetric is a metric for some generic TZ value.
RecursiveGridIsolineBuilder.ZFunc
ZSampleGrid<TZ>	A generic indexed grid of TZ samples.
ZSampleGrid.ZSamplePoint<TZ>
