Constructor Detail

VisADWrapper

public VisADWrapper(java.util.List<javax.vecmath.Point3d> ptsList,
                    double scale)

Initializes the object by creating a common domain field from the geometrical information (the envelope, the width and the height) supplied. The envelope cannot the null, nor can the dimensions by < 1.

Parameters:

ptsList - a list of Points

scale - to multiply to the z-value

Method Detail

addPoints

public final void addPoints(java.util.List<javax.vecmath.Point3d> points)

Add Points to the internal list. Lists without any elements (or null lists) are ignored.

Parameters:

points - to be added to the list

getTriangleCollectionAsList

public final java.util.List<float[][]> getTriangleCollectionAsList()

Generates a list of tringles containing the triangles representing the TIN. Triangles are represented float[3][3]

Returns:

a collection of float[3][3], each of which representing a TIN triangle

clear

public void clear()

Clear all points and invalidate list.
