motile cilia 3d model

Create a realistic 3D model of motile nasal cilia with a loopable animation showing physiological beating and metachronal wave. Scale & geometry: - Cilium length: 5–7 µm (use 6e-6 m if units are meters). - Base diameter ≈ 0.2 µm, spacing 0.2–0.3 µm. - Array: 20×20 µm patch (adjustable). - Cilium segmented (12–24 segments), low-medium poly per cilium (<=200 faces). Materials: - Slightly translucent/shiny material, mild subsurface scattering. - Epithelial patch with subtle bump map. Animation: - Two-phase beat (power stroke + recovery). - Physiological frequency 10–15 Hz (default 12 Hz). Loopable animation. - Power stroke angle 35°–45°, recovery smaller. - Phase lag between neighbors: 0.05–0.12 cycles → produces metachronal wave. - Provide alternative slowed version at 2–3 Hz for visualization. Output: - Export FBX/GLB including animation. Include UVs, normal maps, and simple rig (one bone per cilium with 2–3 joints or morph targets). - Provide JSON metadata: { length_um:6, frequency
