AI-generated overview

Adds lightweight decorative 3D effects to web pages using Zdog, Vanta.js and Vanilla-Tilt.js.

What it does
This skill guides an agent in adding pseudo-3D illustrations, animated WebGL backgrounds and parallax tilt micro-interactions to web pages. It documents the APIs and configuration options of Zdog, Vanta.js and Vanilla-Tilt.js, and provides ready-made HTML, CSS and JavaScript starter files plus reference notes. It also ships Python scripts for generating Zdog illustrations and setting up Vanta effects, and covers performance practices and common pitfalls.
When to use it
Use it when a page needs decorative 3D visuals without heavy frameworks, such as hero-section animated backgrounds, pseudo-3D vector illustrations, or cards and images that tilt in response to pointer or gyroscope input. It suits performance-focused landing pages and micro-interaction work.
Requirements
Runs in a browser and loads Zdog, Vanta.js, Vanilla-Tilt.js and, for some Vanta effects, Three.js or p5.js from CDNs, so network access is needed. It ships executable scripts (scripts/generate_zdog.py, scripts/setup_vanta.py), which implies a Python runtime.

Lightweight 3D Effects Skill

Overview

This skill combines three powerful libraries for decorative 3D elements and micro-interactions:

  • Zdog: Pseudo-3D engine for designer-friendly vector illustrations
  • Vanta.js: Animated 3D backgrounds powered by Three.js/p5.js
  • Vanilla-Tilt.js: Smooth parallax tilt effects responding to mouse/gyroscope

When to Use This Skill

  • Add decorative 3D illustrations without heavy frameworks
  • Create animated backgrounds for hero sections
  • Implement subtle parallax tilt effects on cards/images
  • Build lightweight landing pages with visual depth
  • Add micro-interactions that enhance UX without performance impact

javascript
// Create a grouplet head = new Zdog.Group({  addTo: illo,  translate: { y: -40 },});
// Add shapes to groupnew Zdog.Ellipse({  addTo: head,  diameter: 60,  stroke: 30,  color: '#FED',});
// Eyesnew Zdog.Ellipse({  addTo: head,  diameter: 8,  stroke: 4,  color: '#333',  translate: { x: -10, z: 15 },});
new Zdog.Ellipse({  addTo: head,  diameter: 8,  stroke: 4,  color: '#333',  translate: { x: 10, z: 15 },});
// Mouthnew Zdog.Shape({  addTo: head,  path: [    { x: -10, y: 0 },    {      bezier: [        { x: -5, y: 5 },        { x: 5, y: 5 },        { x: 10, y: 0 },      ],    },  ],  stroke: 2,  color: '#333',  translate: { y: 5, z: 15 },  closed: false,});
// Rotate entire grouphead.rotate.y = Math.PI / 4;

Zdog Animation

javascript
// Continuous rotationfunction animate() {  illo.rotate.y += 0.03;  illo.updateRenderGraph();  requestAnimationFrame(animate);}animate();
// Bounce animationlet t = 0;function bounceAnimate() {  t += 0.05;  illo.translate.y = Math.sin(t) * 20;  illo.updateRenderGraph();  requestAnimationFrame(bounceAnimate);}bounceAnimate();
// Interactive rotation with easinglet targetRotateY = 0;let currentRotateY = 0;
document.addEventListener('mousemove', (event) => {  targetRotateY = (event.clientX / window.innerWidth - 0.5) * Math.PI;});
function smoothAnimate() {  // Ease towards target  currentRotateY += (targetRotateY - currentRotateY) * 0.1;  illo.rotate.y = currentRotateY;  illo.updateRenderGraph();  requestAnimationFrame(smoothAnimate);}smoothAnimate();

<script>  // Vanta background  VANTA.NET({    el: "#vanta-section",    color: 0x3fff00,    backgroundColor: 0x23153c,    points: 10,    maxDistance: 20  });
  // Tilt cards  VanillaTilt.init(document.querySelectorAll(".service-card"), {    max: 15,    speed: 400,    glare: true,    "max-glare": 0.3  });</script>

Performance Best Practices

Zdog Optimization

  1. Limit Shape Count: Keep total shapes under 100 for smooth 60fps
  2. Use Groups: Organize related shapes for easier management
  3. Optimize Animation Loop: Only call updateRenderGraph() when needed
  4. Canvas vs SVG: Canvas is faster for animations, SVG for static illustrations

Vanta.js Optimization

  1. Single Instance: Use only 1-2 Vanta effects per page
  2. Mobile Fallback: Disable on mobile or use static background
  3. Destroy on Unmount: Always call .destroy() in SPAs
  4. Reduce Particle Count: Lower points, quantity for better performance
javascript
// Mobile detection and fallbackconst isMobile = /iPhone|iPad|iPod|Android/i.test(navigator.userAgent);
if (!isMobile) {  VANTA.WAVES({    el: "#hero",    // ... options  });} else {  document.getElementById('hero').style.background = 'linear-gradient(135deg, #667eea 0%, #764ba2 100%)';}

Vanilla-Tilt Optimization

  1. Limit Instances: Apply to visible elements only
  2. Reduce gyroscopeSamples: Lower for better mobile performance
  3. Disable on Low-End Devices: Check device capabilities
  4. Use CSS will-change: Hint browser for transforms
css
.tilt-card {  will-change: transform;}

Common Pitfalls

Pitfall 1: Multiple Vanta Instances

Problem: Multiple Vanta effects cause performance issues

Solution: Use only one effect, or lazy-load effects per section

javascript
// Intersection Observer to load Vanta only when visibleconst observer = new IntersectionObserver((entries) => {  entries.forEach(entry => {    if (entry.isIntersecting && !entry.target.vantaEffect) {      entry.target.vantaEffect = VANTA.WAVES({        el: entry.target,        // ... options      });    }  });});
observer.observe(document.getElementById('hero'));

Pitfall 2: Memory Leaks in SPAs

Problem: Vanta/Tilt not destroyed on component unmount

Solution: Always clean up

javascript
// React useEffect cleanupuseEffect(() => {  const effect = VANTA.WAVES({ el: vantaRef.current });
  return () => {    effect.destroy(); // Important!  };}, []);

Pitfall 3: Zdog Not Rendering

Problem: Canvas appears blank

Causes:

  • Forgot to call updateRenderGraph()
  • Canvas size is 0
  • Shapes are outside view

Solution:

javascript
// Always call updateRenderGraph after shape changesillo.updateRenderGraph();
// Ensure canvas has dimensions<canvas width="240" height="240"></canvas>
// Check shape positions are visiblenew Zdog.Ellipse({  addTo: illo,  diameter: 20,  translate: { z: 0 }, // Keep close to origin});

Pitfall 4: Tilt Not Working on Mobile

Problem: Tilt doesn't respond on mobile devices

Solution: Enable gyroscope controls

javascript
VanillaTilt.init(element, {  gyroscope: true,  gyroscopeMinAngleX: -45,  gyroscopeMaxAngleX: 45});

Pitfall 5: Color Format Confusion (Vanta.js)

Problem: Colors don't work

Cause: Vanta.js uses hex numbers, not strings

javascript
// ❌ Wrongcolor: "#23153c"
// ✅ Correctcolor: 0x23153c
