The Lorenz Attractor plugin for Adobe Photoshop is a powerful, full-feature, Lorenz fractal generation plugin. The Lorenz Attractor is a system of differential equations first studied by Edward Lorenz that is notable for having chaotic solutions under certain parametric values. It is a set of chaotic solutions which, when plotted, resemble a butterfly or figure eight.

Lorenz Attractor is quite complex and can be used to create a variety of generative art for various means including graphic design, motion graphics and illustration.

This implementation of the Lorenz Attractor has been based on the brilliant work of Paul Bourke. It features an iteration slider with independent iteration multipliers for both preview and final renders. It provides the four essential coefficients at the user’s fingertips combined with image control features such as brightness and gamma.

Lorenz Attractor offers the ability to plot the attractor on various axis such as XY, XZ and YZ. Additionally, the user can specify the color density mapping and select from linear, square root or logarithmic, each of which brings out details in the attractor which may not have been previously visible.

Lorenz Attractor provides four different coloring modes such as single color, double color, double blend and spectral for producing vivid and striking attractors.

Lorenz Attractor is 100% multi-threaded capable of using an unlimited number of cores for ultimate speed.

Lorenz Attractor supports both 8 bits / channel and 16 bits / channel color modes for professional workflows.

Iterations: Defines the maximum number of samples to compute. The more samples thrown at the image, the more refined the fractal will be but the longer the computation will take. Using the iteration multipliers, you can provide different quality renders between your preview and final render.

h,a,b,c: Adjusts the four main coefficients that define the attractor shape.

Brightness: Adjusts the brightness of the attractor.

Gamma: Adjusts the gamma of the attractor.

Diffusion: Controls the diffusion of the attractor.

Scale: Adjusts the size of the attractor.

Axis: Specifies which axis to plot the attractor on.

Coloring Density: Specifies the color mapping mode. Each of the modes may reveal different parts of the attractor that may not have been previously visible.

Rnd: Randomizes the coefficients and generates a new fractal.

Color A: Defines attractor color A.

Swap: Interchanges color A with color B.

Rnd: Generates random attractor colors.

Color B: Defines attractor color B.

Coloring Mode: Specifies the coloring mode. Single color uses color A. Double color uses color A & B. Double blend maps color A to the brighter areas and color B to the darker ones. Spectral uses the full color spectrum.

Preview / Render Multipliers: Allows iteration multipliers for high resolution renders.
