Field Detail

STEP_SIZE

public static double STEP_SIZE

Determine the increase in scan size that the sonar method uses; accurary is half this setting (i.e. with a setting of 4 and a distance reported of 100, the actual distance is in the interval [98,102]. Sonar method is used in all cases where distance cannot be determined analytically.

Method Detail

distance

public static double distance(VectorObject object,
                              java.awt.geom.Point2D.Double p,
                              java.awt.Shape inRegion)

Returns the distance between a shape and a point. Looks only within the shape provided. Returns a negative value when nothing is found within this shape.

intersecting

public static final boolean intersecting(java.awt.Shape a,
                                         java.awt.Shape b)
