2D Apical Meristem & Zoetrope Studio

New primordia emerge at the apical meristem center at the divergence angle $\alpha$ while existing primordia accelerate radially outward and expand in size as plastochron age $k_{\text{eff}} = (N - 1) - i$ increases:

\[r_i = c\sqrt{k_{\text{eff}}}\left(\frac{k_{\text{eff}} + 1}{K_0}\right)^{\!a}, \qquad s_i = s_0 + g\sqrt{k_{\text{eff}}}\left(\frac{k_{\text{eff}} + 1}{K_0}\right)^{\!1.15a}, \qquad \theta_i = i \cdot \alpha + \phi_{\text{zoetrope}}\]

Use the preset bar or the collapsible control drawer (<kbd>T</kbd> to toggle, <kbd>F</kbd> for full-screen Theater Mode) to switch between Meristem Life Cycle (Leaves → Petals → Florets → Buds), Full Botanical Leaves, Radiant Flower Petals, Explorer Points (crisp white dots with background-matching halo strokes), Primordia Dots, Concentric Rings, and Botanical Wedges / Scales, tune Radial Acceleration ($a$), Node Growth Factor ($g$), and Life Cycle Organ Span ($F_n$), connect each node to its $k$ Closest Inner Nodes (<kbd>N</kbd>) to reveal Curve Intersections (<kbd>I</kbd>), or engage Zoetrope Strobe (<kbd>Z</kbd>). Drag to pan, scroll to zoom around the cursor, and press <kbd>0</kbd> (or double-click) to recenter.
