subRegion

protected abstract void subRegion(int startX,
                                  int startY,
                                  int subRegionWidth,
                                  int subRegionHeight,
                                  int offsetX,
                                  int offsetY,
                                  int width,
                                  int height,
                                  FractalResult fr)

Compute a subRegion of a fractal data.

This method is invoked by calculateAll(FractalData fd) to prevent the computation of precomputed corners.

Parameters:

startX - the X value of the point this subregion begins

startY - the Y value of the point this subregion begins

subRegionWidth - the width of the subregion

subRegionHeight - the height of the subregion

offsetX - the X offset in the fr.values array

offsetY - the Y offset in the fr.values array

width - the width of the fractal data the specified subregion belongs to

height - the height of the fractal data the specified subregion belongs to

fr - the FractalResult object to fill

calculate

protected abstract int calculate(java.math.BigDecimal cr,
                                 java.math.BigDecimal ci)
