Fractals - Fractal Canopy

A fractal canopy is built by repeated bifurcation: a trunk splits into two branches at a fixed angle from its own direction, each of those splits again at the same angle, and so on for a fixed number of iterations (depth). Every generation shrinks by a constant length ratio relative to its parent, which keeps the whole structure self-similar - zooming into any branch shows the same shape as the whole tree. Asymmetry skews that split unevenly between the two sides - positive values swing the right branch wider than the left (and vice versa for negative values), giving the canopy a wind-blown lean instead of a perfectly mirrored fork. Branch color and thickness are interpolated by depth, from a brown trunk to green tips, purely to make the generations easier to read.
