protected GridEvaluator()

Method Detail

combine

protected double combine(double length,
                         double gLength)

getSegment

public Segment getSegment(Field field,
                          Vector2D source,
                          Vector2D destination)

The function calculates the cost of travelling from one point to another. The cost is a distance betwean points.

Specified by:

getSegment in interface CostEvaluator

Parameters:

field - The field structure

source - The point where the route segment starts

destination - The point where the route segment ends

Returns:

The route is a segment route avoiding exclusion zones.

getCost

public double getCost(Field field,
                      Vector2D source,
                      Vector2D destination)

The alternative way of travel cost calculation for segment. The intermediate points are not gathered into list.

Specified by:

getCost in interface CostEvaluator

Parameters:

field - The field structure

source - The point where the route segment starts

destination - The point where the route segment ends

Returns:

The cost of the segment.

exclZoneAvoid

protected Segment exclZoneAvoid(Segment seg,
                                int depth)

Returns:

a vector with the points to get around ExclusionZone

highestVertex

public Vector2D highestVertex(Polygon2D poly,
                              Vector2D start,
                              Vector2D finalp)

lowestVertex

public Vector2D lowestVertex(Polygon2D poly,
                             Vector2D start,
                             Vector2D finalp)

main

public static void main(java.lang.String[] arg)
