I'm building an interactive L-system tree visualization where string generation rules expand into segments, each tracked with parent, depth, and angle data. The animation reveals branches progressively as growth unfolds, with sway applied per-node using noise offsets that shift angles over time, and leaves bloom at the branch tips. I'll set up turtle graphics interpretation to build the tree structure from the root, then each frame recalculate world positions by applying the base angle plus dynamic sway. Writing the rendering and animation logic... Since nodes are constructed in parent-before-children order, a single forward pass handles all position updates. Leaves appear at tips and on high-depth nodes, while the growth animation staggeres each node's appearance based on its depth, drawing only the fraction of its segment that's currently grown in.
