Nova fractal is a family of fractals related to the Newton fractal. Nova is a formula that is implemented in most[citation needed] fractal art software.

Formula[edit]

The formula for the Nova fractal[citation needed] is a generalization of a Newton fractal:

z \mapsto z - R \frac{z^{p}-1}{pz^{p-1}} + c,

where R is said to be a relaxation constant and p\in\mathbb{C}. If c = 0, this expression reduces to the Newton fractal formula:

z \mapsto z - R \frac{f}{f'}

for f=z^p-1. Usually, p is assigned the value 3, while R is an adjustable parameter, and c is the location variable, for a "Mandelbrot Nova".
