Method Summary

boolean

almostEquals(GeometricObject2D obj, double eps) Checks if the two objects are similar up to a given threshold value.

Method Detail

almostEquals

boolean almostEquals(GeometricObject2D obj,
                     double eps)

Checks if the two objects are similar up to a given threshold value. This method can be used to compare the results of geometric computations, that introduce errors due to numerical computations.

Parameters:

obj - the object to compare

eps - a threshold value, for example the minimal coordinate difference

Returns:

true if both object have the same value up to the threshold
