XenoDream Jux v2.300

[Togijak]

Jux is a 2D Julia and Mandelbrot fractal explorer with advanced lighting options. It has a variety of formulas and a real-time Julia set explorer. Easy to change color and lighting, mostly with real-time preview. It has built in formulas, and allows switching between points on the Mandelbrot set and corresponding Julia sets. It uses distance estimation to define the set boundary, and coloring and/or lighting based on distance, potential, textures, fibers and field lines. Previewing, exploring and rendering can each use multiple cores. There is no formula editor or scripting.

Features
• Easy switching between Mandelbrot and Julia sets
• Julia explorer shows Julia set thumbnail corresponding to mouse position in preview
• A selection of formulas, mostly generic with parameters
• Fully multi-core for preview, explorer and rendering
• Render large pictures with full anti-aliasing (when registered)
• Batch rendering (when registered)
• Numeric controls can be dragged like sliders
• 12 steps of undo/redo
• Easily share parameters in social media, with copy/paste to the clipboard
• Memory spots for temporary storage of formulas, coloring or lighting
• Save your favorite settings as presets (formulas, coloring, lighting, gradients)
• Hundreds of system presets included
• One-click switching between 15 default color schemes
• Gradient editor that includes tools to capture linear or randomized gradients
• Coloring based on potential, distance estimate, mean z, basins, textures, fibers, field lines
• Adjust color and lighting controls with realtime preview
• Powerful heightfield lighting effects
• Materials that can include reflection, refraction, angular filtering and displacement mapping
• Use panoramic or ordinary images as environment maps for reflection and refraction

The free version is limited to 640x480 anti-aliased rendering. Register to unlock the render size controls, enable batch rendering, allow exporting gradients in .ugr format, and support further development.

Note: if you are using an earlier Jux version, it is recommended to uninstall it, then install Jux 1.7 to the same folder. Use the same location for personal data as before. If you already registered Jux, it is valid for v1.7 too: updating is free. If you lose your registration key, just email us.

Formulas and navigation
Jux can draw both Julia and Mandelbrot fractals.
• When drawing a Mandelbrot set, you can point the mouse at any part of it and see the corresponding Julia set in the thumbnail
• For Julia sets you can explore variations by moving the mouse relative to the center of the preview
• Shift-click or press J in the preview to switch to the new Julia
• Alt-drag vertically or Ctrl-drag a rectangle in the preview to zoom; pan the preview by dragging it
• Extended precision numbers allow zooming up to 10^16
• Jux automatically finds critical points to correctly render convergent regions in Julia fractals
• For Mandelbrot fractals you can choose which critical points to use
• Choose from a list of built in formulas (there is no formula editor)
• Jux V1.7 has a good selection of polynomial, rational polynomial and Newton formulas, some Ducks and Kaliset variations, and three with sines
• Most formulas have parameters to cover the range of possibilities. Some include Abs modes.
Here are some examples of different formulas and coloring (without lighting).

Coloring
There are many possible ways to color Julia fractals. Jux has built-in methods chosen for their simplicity, flexibility and aesthetics. You can use coloring alone, or modify it with heightfield lighting effects.
• The basic coloring can use continuous potential, distance estimation or mean |z|
• Exterior (divergent) regions and interior (convergent) regions have separate coloring controls, with their own texture engines
• Coloring for the In Set region based on mean |z| or angle.
• Exterior regions can have a Fibers coloring method instead of texture
• Interior regions can also have field lines and turbulence, and vary the color per basin or sub-basin
• All coloring parameters (except Fibers) can update the preview in realtime
• Coloring uses several gradients, with a powerful gradient editor and 900+ presets included
• Capturing gradients (linear or randomized) from the desktop is easy
• Import gradients from UltraFractal .ugr or Fractint .map files

Lighting
Jux can add lighting effects to bring the fractals into 3D. The fractal is calculated as a height field in a 3D lighting environment.
• Height field contours based on potential, distance estimate or mean z
• Separate height field adjustment for in set, exterior and interior regions
• Add displacement from textures, fibers or field lines
• Up to 10 directional light sources plus ambient and fill light
• Field of view can be adjusted between 1 and 360 degrees
• Environment mapping for reflection and refraction using panoramic or ordinary images
• Use your own images or one of 12 supplied panoramic images
• Material properties independent of light sources and formulas
• Materials can use the fractal coloring or override it with other effects
• Optionally use different materials for interior and exterior regions
• Materials can have a mix of diffuse, highlights, emission, reflection and refraction
• Use gradients to filter the reflected and transmitted light by angle
• Add displacement mapping with a variety of noise or patterns
• All lighting parameters can update the preview in realtime (or near enough)
Here are some examples of lighting with various materials.

What's new in v2.300:
Main window
- In the pixel inspector, the OT info now includes the trap number.
- Minor operational changes to fix UI issues.
Gradient editor
- Increased editor width.
- The colorpicker is no longer modal, so you can keep it open while editing the gradient.
Formula tab
- Added the Wavers formula.
- Added a parameter to Sinoration formula to choose the function (Sin, Tan or SinH).
Coloring tab
- Added one new Orbit Trap shape: Leaf 4.
Lighting tab
- The Orbit Traps panel is now enabled if Orbit Traps are enabled, regardless of whether any pixels have OT.

System Requirements
Jux requires Windows 2k/XP/Vista/7/8/10 or later, either 32 or 64 bit versions. It may run on earlier versions.
Jux should work in any Windows emulation on an Intel Mac or Linux.
Jux can use all available CPU processors and cores.
The graphics card does not matter, as Jux does not use it for computation
