Warp Tunnel shader for WebGL

Copy embed gives one block to paste into any page or site builder, no setup. For your own code: add warp-tunnel.js, ittybitty-shader.js, runtime.js, pointer.js next to this page. Highlighted values follow the controls.

<!-- Quickest: one element. Size it with CSS; it fills its box. -->
<script type="module" src="./ittybitty-shader.js"></script>
<ittybitty-shader effect="warp-tunnel" style="width: 100%; height: 480px;"></ittybitty-shader>

<!-- Or with JavaScript, for full control: -->
<canvas id="warp-tunnel" aria-hidden="true" style="width: 100%; height: 480px; display: block"></canvas>

<script type="module">
  import { warpTunnel } from './warp-tunnel.js';

  const canvas = document.getElementById('warp-tunnel');
  const effect = warpTunnel(canvas, {
    showBackground: true,
    speed: 0.6,
    zoom: 1,
    density: 90,
    length: 0.5,
    twist: 0.15,
    x: 0.5,
    y: 0.5,
    style: 'streaks',
    interactive: true,
    responsiveness: 0.5,
    palette: [[0, '#7cc6ff'], [0.5, '#f5f2ff'], [1, '#b48cff']],
    background: '#05050a',
    // Performance
    dpr: 1.5,
    adaptive: true,
  });

  // Later: effect.set(…), effect.pause(), effect.resume(), effect.destroy()
</script>
