java.lang.Object
  raar.shape.RAShapeMath

public class RAShapeMath
extends java.lang.Object

Mathematical tools for shapes. For distance measurements, this version uses a sonar-like approach, which is reasonably fast and accurate. A future version could include an analytical distance function for the most common shapes. MADE IN SWITZERLAND

Field Summary

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 [98,104]....

Constructor Summary

RAShapeMath()

Method Summary

static double	distance(java.awt.Shape s, java.awt.geom.Point2D.Double p, java.awt.Shape inRegion) Returns the (approximate) distance between a shape and a point.
static boolean	intersecting(java.awt.Shape a, java.awt.Shape b) http://forum.java.sun.com/thread.jsp?

Method Detail

distance

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

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

intersecting

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