How to Use Fractal Tree

1
Set Branch Depth
Adjust the depth slider between 1 and 12 to choose branch density.
2
Configure Angle & Length
Adjust the split angle and branch decay ratio to create narrow poplars or wide spreading oaks.
3
Select Colors
Pick trunk and leaf colors, such as natural green oak or vibrant cherry blossom pink.
4
Export Image
Download your generated fractal tree as a PNG graphic or clean vector SVG.

Key Features

Customizable Branching Physics
Real-time control over branch angle (15°–60°), length scaling ratios (0.5–0.85), and recursion depth.
Branch Tapering & Foliage
Automatically renders tapered wooden trunks and colored leaf foliage on delicate terminal branches.
Crisp Multi-Format Export
Download high-resolution PNG image files or pure vector SVG files for laser engraving and design.
Touch & Pan Support
Effortlessly inspect intricate branching canopies with intuitive single-touch drag and multi-touch zoom.

Common Use Cases

  • Procedural botanical generation and foliage modeling for video games and architectural renders.
  • Graphic design, digital illustration, and minimalist modern poster generation.
  • Educational demonstrations of recursive algorithms, self-similarity, and natural fractal geometry.
  • Vector silhouettes for wood cutting, vinyl plotting, and CNC laser engraving.

Frequently Asked Questions

A fractal tree is a geometric figure generated by repeatedly splitting line segments into smaller child branches at fixed angles and scale ratios, modeling the natural branching structure of trees, bronchial passageways, and river networks.

For a binary branching tree of depth $d$, the total number of branches is $2^d - 1$. At depth 8 there are 255 branches, and at depth 12 there are 4,095 branches.

Because branch count doubles exponentially with each level ($2^d$), higher depths quickly exceed tens of thousands of vectors. Capping at 12 preserves high performance and 60 FPS client responsiveness.
