Method Detail

addListener

public void addListener(ConvexPolygonIntersector.Listener l)

removeListener

public void removeListener(ConvexPolygonIntersector.Listener l)

setDistanceTolerance

public void setDistanceTolerance(double tol)

Sets the distance tolerance. This should be the smallest distance value that can be reliably computed. If tol is set to AUTOMATIC, then the distance tolerance is computed automatically from the data.

Parameters:

tol - distance tolerance

getDistanceTolerance

public double getDistanceTolerance()

Gets the distance tolerance.

Returns:

distance tolerance
