Overview
Mandelbrot creates an image from the mathematical fractal of the same name. Each pixel is computed by iterating a complex formula - the number of iterations before divergence gives the color.
Advantages:
- Infinite zoom - detail visible at every scale (no pixelation).
- Hypnotic animation by animating Zoom or Iterations.
- No visible repetition (unlike tiled textures).

Inputs
- Effect Mask (blue) - optional. Limits the fractal generation to an area.
Setup
Mandelbrot → Merge 2D (or as a mask, or a displacement source)
Noise tab (shape of the fractal)
- Position X / Y
- Starting point in the complex plane. Moves the "camera" to explore different areas of the fractal. Fine coordinates around (0, 0) to see the classic set.
- Zoom
- Magnification factor. Unlimited in practice - you can zoom indefinitely into the edges of the set to reveal ever more detail.
- Escape Limit
- Sets the value at which the iteration stops. Low values create soft halos around the shapes; high values give crisp edges.
- Iterations
- Number of calculations per pixel. Higher = more detail, especially at the edges. Animating it simulates the set "growing" progressively.
- Rotation
- Rotation of the pattern. Recomputed on every angle change - slow when combined with a high Zoom.
Color tab
- Gradient Method
- Type of gradient used to color the fractal edges.
- Continuous Potential
- Smooth gradient mode: the edges of the pattern fade into the background color. A smooth look, ideal for abstract renders.
- Iterations Mode
- An alternative that produces solid edges (distinct color bands depending on the number of iterations reached).
- Gradient Curve
- Adjusts the width of the transition between the pattern and the background.
- R / G / B / A Phase / Repetitions
- Per-channel parameters for color generation. Animating the Phase values produces a psychedelic color cycling effect.
Use cases
- Sci-fi title - a Mandelbrot animated in Zoom + Rotation as the background behind sci-fi text. An instant "mathematical infinity" look.
- Abstract motion graphics - animate the Phase of the RGB channels for a hypnotic color cycle.
- Intro / logo reveal - a fast zoom into the Mandelbrot set, revealing the logo at the end.
- Displacement / distortion source - the fractal as the input of a
Displace 2Dfor a self-similar organic distortion. - Complex mask - a threshold on a fractal = a mask with fine detail that would be impossible to draw by hand.
- Conference / exhibition background - a gentle Mandelbrot loop = an "intellectual" background that catches the eye without distracting.
Tips
- Zoom gradually into the edges of the set - the most visually interesting areas are at the edges of the central "beetle". Explore (−0.7, 0), (0.3, 0.6), (−1.4, 0) with a progressive Zoom.
- High Iterations = slow render - 100 iterations are often enough. 1000+ gives extreme detail but is expensive.
- Animate the R/G/B Phase from 0 to 1 over the length of the shot = a full pulsing color cycle.
- Continuous Potential for a modern look, Iterations Mode for a retro/8-bit look.
- For a smooth zoom, animate Zoom with a very long ease (exponential curve) - the log10 of the Zoom evolves more naturally than a linear value.
- For a static hypnotic effect, keep Zoom fixed + animate Rotation slowly.
