This example visualizes a procedural 3D fractal tree in a rainbow color gradient, generated recursively with Three.js. The scene uses a perspective camera with automatic rotation and orbit controls disabled, while dynamic branch angles animate continuously. It employs Three.js MeshPhongMaterial for emissive, shiny branch surfaces, AmbientLight, DirectionalLight with soft shadow mapping, PointLight, and a ground plane. Each branch and connection sphere recalculates its time-varying orientation every frame from stored base parameters, creating an organic, living growth effect against a dark starry backdrop.
