Class NodeMapper

java.lang.Object

walker.blue.path.lib.node.NodeMapper

public class NodeMapper
extends java.lang.Object

This class can be used to convert between the grid coordinate system that uses indices to determine the distance between nodes and a real world coordinate system which uses real world units. Assumptions must be made for this class to work properly: 1) The floor heights of the building must be all equal.

Example: If node distance is 5, the distance between two nodes in a grid that are adjacent to each other would be 1, whereas the real world distance would be 5.
