Method Detail

getMinDistance

float getMinDistance(int value,
                     java.util.BitSet set)

Calculates the distance between the closest point in this BitSet and the given value.

getMinDistance

float getMinDistance(int value,
                     java.util.Vector<Point3D> setPoints)

Calculates the distance between the closest point in this Vector and the given value.

getEdgePoints

java.util.BitSet getEdgePoints(java.util.BitSet set)

Finds the points of the given BitSet which has at least one neighbor (not including diagonals) not in the BitSet.

isBoundaryPoint

connectNearNeighbors

java.util.BitSet connectNearNeighbors(int loc,
                                      java.util.BitSet connectingRegion,
                                      int maxNeighborDistance)

Set elements of the returned BitSet meet at least one of the following criteria:

1. Element is set in connectingRegion.
2. Walking up, down, right, and/or left from loc to this element requires less than or equal to maxNeighborDistance steps.
