Field Detail

POINTS_TO_TIN

public static final int POINTS_TO_TIN

Indicates a transformation from points to TIN.

TIN_TO_POINTS

public static final int TIN_TO_POINTS

Indicates a transformation from TIN to points.

Constructor Detail

TinPointsThread

public TinPointsThread(GISFrame gisFrame,
                       int direction)

Converts between TIN and point collection. If direction is TIN_TO_POINTS, it will extract the vertices as a collection of points. Otherwise it will attempt to perform a Delaunay triangulation to create a TIN.

Parameters:

gisFrame - GUI containing TIN or points.

direction - Direction of transformation (either POINTS_TO_TIN or TIN_TO_POINTS).

Method Detail

doProcessing

public void doProcessing()

Convert between the TIN and point representation in the direction specified in the constructor (direction). A newly created vector map containing either the points extracted from a supplied TIN or the TIN created from the supplied points, is added as a primary vector map to the GISFrame provided to the constructor. It can be retrieved directly via this class's getVectorMap() method, or by calling gisFrame.getVectorMap1();.

Note that this method will be called automatically if this is run as a threaded process (e.g. myTinPointsThread.start()). Alternatively it can be called directly as a non-threaded process.

Specified by:

doProcessing in class LSThread

GISFrame

getVectorMap

public VectorMap getVectorMap()

Retrieves either a TIN or collection of points depending on the direction of conversion specified in the constructor.

Returns:

Vector map containing TIN or points, or null if process yet to take place.
