This interactive 3D simulation depicts a microscopic aquatic environment teeming with protozoa. Three distinct types—paramecium, amoeba, and euglena—each with unique shapes and movement patterns, swim and crawl through a transparent water sphere. The scene is rendered with Three.js, using MeshPhongMaterial for the organisms and a particle system for organic debris. Camera controls allow rotation and zoom, while directional and point lights illuminate the environment, creating a visually rich educational tool.
