由数千个数学驱动点构成的交互式WebGL鱿鱼群

Build an interactive squid shoal in WebGL as one self-contained HTML page. Use no imported models, sprites or pre-rendered animation: every squid body is a cloud of thousands of points computed in real time from equations. One set of equations drives a rhythmic jet pulse of the mantle, another bends the fins, and the tentacles follow the squid's own past positions so they lag, curl and whip through turns. Give the shoal inertia and flocking-style movement on a deep dark background with soft glowing translucent bodies. Add a compact control panel with colour pickers and sliders for speed and count, and make the squids panic and scatter when the pointer touches the water. Done means a smooth, continuously animated school that reacts to input and recolours live.
