Understanding the Twindragon Curve
The Twindragon Curve (also known as the Davis-Knuth dragon) is a self-similar fractal constructed by joining two Heighway Dragon curves back-to-back. It is the boundary of the set of complex numbers that can be represented in base -1 + i using only digits 0 and 1.
The base i-1 expansion
In mathematics, the Twin Dragon is defined as the attractor of the following Iterated Function System (IFS) in the complex plane:
f₁(z) = z / (i-1) f₂(z) = (z + 1) / (i-1)Every Gaussian integer z ∈ ℤ[i] admits a unique representation in this number system, meaning there are no gaps when translating copies of the fractal along the integer grid.
Periodic Tiling
Unlike many complex fractals that do not fit together, the Twindragon is a rep-tile (replicating tile). This means it can tile the entire 2D plane periodically with translations along the lattice ℤ[i] (Gaussian integers) without overlaps or gaps. You can toggle the Tiling Grid Mode parameters to visually inspect how multiple Twindragons lock together like puzzles pieces.
Professional Twindragon Curve Generator for Everyone
An interactive simulator for the Twindragon Curve (also known as the Davis-Knuth dragon), a self-similar fractal constructed by joining two Heighway Dragon curves back-to-back. Beyond standard curve tracing, this generator features a live Tessellation Grid Mode that demonstrates the Twindragon's unique property to tile the 2-dimensional plane periodically. Adjust recursion depths, line widths, and playback speed. Explore custom color modes including solid, gradient, rainbow, dual-tone contrasting, or a grid-tiling palette. Interactively zoom and pan across dense vector segments. Export high-quality transparent PNGs or copy scalable SVG path coordinates. Processed 100% locally and privately in your browser.

Frequently Asked Questions
Common questions about our Twindragon Curve Generator tool.
What is a Twindragon Curve?
The Twindragon (also known as the Davis-Knuth dragon) is a fractal constructed by joining two Heighway Dragon curves back-to-back. It is the boundary of the complex base i-1 number system using digits 0 and 1.
How does the Twindragon tile the plane?
Unlike most fractals, the Twindragon is a periodic tile. The translates of the Twindragon along the Gaussian integer lattice Z[i] fit together perfectly without overlapping or leaving any gaps, tiling the entire 2D plane.
Why is the depth slider limited?
As recursion depth increases, the number of segments grows exponentially (2^depth). At depth 12, a single Twindragon draws 4,096 segments per path. To prevent browser threading locks, we cap the depth while preserving high-definition rendering.
