Method Detail

getUseInjectiveCurve

public boolean getUseInjectiveCurve()

Returns the value of the useInjectiveCurves property.

setUseInjectiveCurves

public void setUseInjectiveCurves(boolean useInjectiveCurves)

Sets the value of the setUseInjectiveCurves property. This property determines which of two approximations of the Sierpinski curve is drawn.

Parameters:

useInjectiveCurves - If set to true, then an injective approximation is used for the Sierpinski curve. Otherwise, a non-injective approximation is used.

getActionsForView

public ActionList getActionsForView(View view)

Adds a submenu that contains commands for selecting the value of the segmentChoice property.

Overrides:

getActionsForView in class Exhibit

computeNextLevel

protected Complex[] computeNextLevel(Complex[] sierpinskiCurve,
                                     int computedLevel)

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:

sierpinskiCurve - 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.
