public class Koch
extends RepeatedSegmentFractal

Represents a Koch "snowflake" curve. The standard Koch curve is produced when the "fractality" parameter is 1/3.

Description copied from class: RepeatedSegmentFractal

This abstract method computes one approximation level from the previous one, which has already been computed. This abstract method must be defined in any concrete subclass.

Specified by:

computeNextLevel in class RepeatedSegmentFractal

Parameters:

kochCurve - This array stores the points that have been computed for the current approximation level. This array can be null, if the computedLevel is zero.

computedLevel - This is the approximation level that has been comptuted to get the points in curvePoints. A zero value for this paramter means that the first, or base level, approximation should be computed.

Returns:

An array containing the points in the next level approximation of the curve.
