Default Julia-specific palette.
Type:
  • JULIA_PALETTE
Source:

(static, constant) DEFAULT_JULIA_THEME_COLOR :PALETTE

Default color used based on the initial Julia coloring. It's accent color / 1.9 brightness factor that is hardcoded in the updateColorTheme method.
Type:
  • PALETTE
Source:

(static, constant) DEFAULT_MANDELBROT_THEME_COLOR :PALETTE

Default color used based on the initial Mandelbrot coloring. It's an accent color / 1.9 brightness factor that is hardcoded in the updateColorTheme method.
Type:
  • PALETTE

(static, constant) DEFAULT_RIEMANN_THEME_COLOR :PALETTE

Default color used for Riemann mode UI theming (light blue #4FC3F7)
Type:
  • PALETTE
Source:

(static, constant) EASE_TYPE :function

Ease in-out transition types matching functions in the Utils module
Type:
  • function
Source:

(static, constant) FF_ADAPTIVE_QUALITY :boolean

Feature flag for adaptive quality control. When enabled, automatically adjusts iteration count based on GPU performance.
Type:
  • boolean
Source:

(static, constant) FF_DEMO_ALWAYS_RESETS :boolean

When set to true, demo animation will always start from the beginning rather than continue where it's been interrupted.
Type:
  • boolean
Source:

(static, constant) FF_HOTKEY_HINTS :boolean

Experimental: Highlights the first letter of all buttons in the header panel. The first letter is styled with the accent color to indicate keyboard shortcuts.
Type:
  • boolean
Source:

(static, constant) FF_PERSISTENT_FRACTAL_SWITCHING

Allows switching between fractal while keeping the params to allow Mandelbrot and Julia to match each other
Source:

(static, constant) FF_PERSISTENT_FRACTAL_SWITCHING_BUTTON_DISPLAYED :boolean

Feature flag controlling the display of the persistent fractal switching button in the UI. When enabled, users can see a button to toggle between fractal types while maintaining the current parameters for seamless transitions between Mandelbrot and Julia sets.
Type:
  • boolean
Since:
  • 1.9
Source:

(static, constant) FF_RANDOM_APP_NAME :boolean

When enabled, the app name will be randomly generated based on APP.suffixes
Type:
  • boolean
Source:

(static, constant) FF_RIEMANN_COLOR_SLIDERS :boolean

Shows the RGB frequency and contour strength sliders in Riemann display dropdown. These are advanced controls for fine-tuning the domain coloring visualization.
Type:
  • boolean
Source:

(static, constant) FF_RIEMANN_SHADER_DROPDOWN :boolean

Shows the manual shader selection dropdown in Riemann mode. When disabled, shader switching happens automatically based on viewing region.
Type:
  • boolean
Source:

(static, constant) FF_RIEMANN_TOUR_MUSIC :boolean

Enables atmospheric background music during the Riemann zeta tour. Requires an audio file at src/audio/riemann-tour.mp3
Type:
  • boolean
Source:

Enum of fractal types
Type:
  • number
Source:

(static, constant) LOG_LEVEL :Object

Type:

Source:

(static, constant) PI :number|number

PI
Type:
  • number | number
Source:

(static, constant) RIEMANN_DOUBLE_PRECISION_THRESHOLD :number

Imaginary value (t) threshold above which the double-precision shader is used. At t > 1000, regular float precision starts degrading noticeably.
Type:
