[edit] About
Nova fractal refers to a family of fractals related to the newton fractal. The formula was named by Paul Derbyshire. Nova is a formula that is implemented in most Fractal Art software.
[edit] Formula
The formula for novaMandelbrot is:
- z = z − relax · ( zpower − 1 ) / ( power · zpower − 1 ) + pixel
[edit] Nova variants
There are a number of related variants of the nova fractal formula, that combine parts of other fractals such as the phoenix fractal and the halley fractal, as well as variants that "double-up" parts of the calculation.
The nova fractal formulae have names like DoubleNova, HalleyNova and PhoenixDoubleNova, each one has a Mandelbrot and a Julia variant.
[edit] public nova fractal formulae — dmj.ufr
The nova formulae that are publicly available,[1] include a 'relaxation' parameter, which increases the complexity of the resulting image under certain settings.
This formula generates 2-dimensionally dense high-frequency detail when the 'relaxation.real' parameter is increased. This is especially true inside the nova lake.
Because of the high level of detail that Nova Fractal can create it can be a challenge to capture a well antialiased image of it.
