Houdini 20.5 Nodes Copernicus nodes

Julia Fractal Copernicus node

Computes the Julia set to create a fractal.

On this page

This node computes the Julia set for provided parameterizations. Use this node when you want to add chaotic and fractal aesthetics to your images.

The Julia set is related to the Mandelbrot set . If parameters to the Julia set are connected, then the parameters form a point in the Mandelbrot set.

Parameters

Signature

The layer type that the node outputs. You can output a mono (Float) layer of the normalized time-to-escape or an ID (Integer) layer that contains the actual number of iterations before escape.

See Signatures for more information.

Scale

The amount to scale the incoming x and y image coordinates.

Real Coefficient

The real coefficient to set up the Julia fractal.

Imaginary Coefficient

The imaginary coefficient to set up the Julia fractal.

Escape Radius

The threshold at which the point is considered to have escaped.

Maximum Iterations

The number of iterations at which to conclude the point hasn’t escaped.

Inputs

size_ref

A representative layer that determines the size of the output image and controls the metadata.

Outputs

fractal

The mono layer that includes the escape time or the ID layer of the exact integers of escape iterations.

Tip

You can use the Mono to RGB COP to convert the mono layer output into a colorful image.
