Class DelaunayOverlap

java.lang.Object
  visad.Delaunay
      visad.DelaunayOverlap

All Implemented Interfaces:

java.io.Serializable

public class DelaunayOverlap
extends Delaunay

DelaunayOverlap quickly constructs a triangulation of a series of partially overlapping two-dimensional gridded sets.

Grids should be aligned so that they overlap in a roughly vertical column (i.e., as samples[*][1] increases or decreases, the grid number increases or decreases respectively). DelaunayOverlap does not handle grids which overlap across a horizontal row.

Constructor Detail

DelaunayOverlap

public DelaunayOverlap(float[][] samples,
                       int lenx,
                       int leny)
                throws VisADException

Construct a Delaunay triangulation of the points in the samples array, which are a sequence of 2-D grids of size lenx * leny, and which may overlap with each other. This situation can arise when each grid is a scan from a polar orbiting satellite and the scans are perpendicular to the direction of travel of the satellite. The scan grids widen away from the satellite sub-point and can overlap.

Parameters:

samples - locations of points for topology - dimensioned float[dimension][number_of_points]

lenx - x size of scan grid

leny - y size of scan grid

Throws:

VisADException - a VisAD error occurred

Method Detail

main

public static void main(java.lang.String[] argv)
                 throws VisADException

run 'java visad.DelaunayOverlap' to test the DelaunayOverlap class

Parameters:

argv - command line arguments

Throws:

VisADException - a VisAD error occurred
