Ecosystem Population Dynamics (3D)

This is a full 3D ecosystem model built on the classic three-trophic-level system ecologists use to describe population change: producers (plants) grow logistically toward a carrying capacity, herbivores graze on producers and reproduce in proportion to what they eat, and predators hunt herbivores in a Lotka-Volterra-style coupling. Each population is rendered as a living group of instanced 3D individuals — green plants that sway and thicken as they grow, tan herbivores that wander the terrain grazing, and red predators that roam faster and thin the herd — with the displayed count of each group following the differential equations frame by frame rather than a static illustration. Tune the producer growth rate, grazing rate, predation rate and carrying capacity to push the ecosystem toward collapse, explosive growth, or the boom-bust oscillation classic predator-prey systems are known for, and orbit the scene to watch the food chain play out in three dimensions.
