Hologram shader for WebGL

Copy embed gives one block to paste into any page or site builder, no setup. For your own code: add hologram.js, ittybitty-shader.js, runtime.js, pointer.js, texture.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="hologram" style="width: 100%; aspect-ratio: 16 / 10;"></ittybitty-shader>

<!-- Or with JavaScript, for full control: -->
<canvas id="hologram" aria-hidden="true" style="width: 100%; aspect-ratio: 16 / 10; display: block"></canvas>

<script type="module">
  import { hologram } from './hologram.js';

  const canvas = document.getElementById('hologram');
  const effect = hologram(canvas, {
    showBackground: true,
    showScanlines: true,
    image: '/examples/still-life.webp',
    speed: 1,
    lines: 0.6,
    glitch: 0.4,
    glow: 0.6,
    opacity: 0.8,
    interactive: true,
    responsiveness: 0.5,
    colour: '#4fd8ff',
    background: '#040810',
    // Performance
    dpr: 2,
    adaptive: true,
  });

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