Introduction to the tool and how to use it
Online numbered fractal tree generator: canvas draws the fractal tree recursively in real time and labels each node with a number. Enter one group of
Four shapes: binary tree, ternary tree, Pythagoras tree (using squares), and the Sierpinski triangle. Four numbering rules: sequential increment, binary-tree path numbering (left child = parent×2, right child = parent×2+1), Fibonacci along depth, and seeded deterministic random values.
Notes: angle jitter uses a custom PRNG, so rebuilding with the same seed and parameters twice yields an identical node array; a ternary tree at depth 12 approaches 800000 nodes, and the tool truncates to the node cap automatically with a notice.
