Map recursion depth to color, thickness, and leaves.

Concept explanation

Depth is data. The sketch can use it to choose stroke weight, branch color, and leaf placement so recursion becomes easier to read.

Try it

Map recursion depth to color, thickness, and leaves.

Code fragment

const t = level / maxDepth;
stroke(lerpColor(trunk, leaf, t));

What to observe

  • Older branches can be darker and thicker.
  • Newer branches can be lighter and thinner.
  • Leaves mark base cases visually.

Small challenge

Use high depth and decide whether color or thickness helps more.
