Method Detail

splitInterval

public static boolean splitInterval(double beginIncluded,
                                    double endExcluded,
                                    TriMarkers currentTriangle,
                                    Deque<TriMarkers> outsideTriangles,
                                    Deque<TriMarkers> intervalTriangles)
                             throws com.vividsolutions.jts.geom.TopologyException

Use interval to split the triangle into severals ones

Returns:

False if the entire geometry is outside of the region, true if outsideTriangles or intervalTriangles has been updated.

Throws:

com.vividsolutions.jts.geom.TopologyException

processTriangle

public static Map<Short,Deque<TriMarkers>> processTriangle(TriMarkers triangleData,
                                                           List<Double> isoLvls)
                                                    throws com.vividsolutions.jts.geom.TopologyException

Parameters:

triangleData - Triangle Coordinates and Marker values

isoLvls - Iso level to extract.

Returns:

processedTriangles Return sub-triangle corresponding to iso levels. iso level are stored in markers (same for m0,m1,m2)

Throws:

com.vividsolutions.jts.geom.TopologyException
