Particle Packing Visualization Prompt

Particles represent objects, with mass proportional to true size. Initial random placement inside silhouette. Forces: - Zone attraction: each particle is assigned a zone; a potential field pulls it toward the zone's target region. - Repulsion between particles (size-dependent) to prevent overlap, achieving high density. - Boundary force: strong repulsion near silhouette edge to maintain Ne≥0.88. - Alignment force: objects rotate to align with local silhouette tangent for aesthetic flow. Simulation runs until convergence (stable packing with Dn≥0.86, Ct≥0.88). Post-processing: identify zone clusters, compute centroid, draw leader lines to nearest margin. Add labels, unit key, source. Lighting: compute soft shadows by casting rays from a single overhead light direction. Evaluate J; adjust simulation parameters if constraints not met. Render final configuration as 8K flat lay.
