setConstrainedToCircle
public void setConstrainedToCircle(boolean isConstrainedToCircle) Sets whether generated points are constrained to lie within a circle contained within each grid cell. This provides greater separation between points in adjacent cells.The default is to not be constrained to a circle.
- Parameters:
isConstrainedToCircle

-
setGutterFraction
public void setGutterFraction(double gutterFraction) Sets the fraction of the grid cell side which will be treated as a gutter, in which no points will be created. The provided value is clamped to the range [0.0, 1.0].- Parameters:
gutterFraction
