Choose between Fractal Tree (recursive branching) or L-System (string rewriting) generation.

Number of recursive iterations. Higher values create more complex patterns but may be slower to render.

Branching angle in degrees. Controls how wide the tree or pattern spreads.

Initial branch length. Larger values create bigger patterns.

Starting string for L-System. Usually a single character like 'F'.

Rewriting rule for L-System. Format: 'F→F[+F]F[-F]F' where F is replaced with the pattern.
