lightweight-3d-effects — Claude Code skill: 3D without heavy
A skill for decorative 3D elements and micro-interactions: pseudo-3D illustrations, animated backgrounds, tilt on hover. Useful when a landing page needs depth without a full WebGL stack.
npx skills add freshtechbro/claudedesignskills --skill lightweight-3d-effects -a claude-codeWhat lightweight-3d-effects does
The skill bundles three libraries around one job. Zdog draws flat, rounded shapes in 3D space on Canvas or SVG. Vanta.js handles animated backgrounds on top of Three.js. Vanilla-Tilt.js adds parallax tilt that follows the mouse or gyroscope.
What you get is working code: Zdog primitives (ellipse, rect, rounded rect, polygon, line, bezier curve), groups for building composite models, and three animation patterns — continuous rotation, a sine bounce, and easing a rotation angle toward a target. The Vanta.js section shows Waves and Clouds configured with colors and wave parameters.
Vanta.js needs Three.js loaded first, otherwise the background never starts — that is the usual snag. Zdog ships at roughly 28kb minified, Vanta.js with Three.js at about 120KB. If your project already runs a real 3D engine, skip these: they are for decorative depth, not for scenes.
What it helps with
- add a pseudo-3D illustration to a landing page without a Three.js scene
- build an animated background for a hero section
- make cards tilt under the cursor
- animate a static block with a rotating shape
- assemble a composite model from simple Zdog shapes using groups
Example prompts for the agent
- Add a Zdog pseudo-3D illustration to the landing page: a spinning cube built from rects
- Set up a Vanta.js Waves background for the hero section with color 0x23153c
- Add parallax tilt to the product cards with Vanilla-Tilt.js

What does lightweight-3d-effects do?
It gives the agent code samples and settings for decorative 3D: pseudo-3D shapes with Zdog, animated backgrounds with Vanta.js, and element tilt via Vanilla-Tilt.js.
What libraries does the skill rely on?
Zdog, Vanta.js and Vanilla-Tilt.js. Vanta.js also needs Three.js loaded separately — without it the backgrounds will not run.

- Smooth animations
### Basic Setup
```html
<!DOCTYPE html>
<html>
<head>
<script src="https://unpkg.com/zdog@1/dist/zdog.dist.min.js"></script>
<style>
.zdog-canvas {
display: block;
margin: 0 auto;
background: #FDB;
cursor: move;
}
</style>
</head>
<body>
<canvas class="zdog-canvas" width="240" height="240"></canvas>
<script>
let isSpinning = true;
let illo = new Zdog.Illustration({
element: '.zdog-canvas',
zoom: 4,
dragRotate: true,
onDragStart: function() {
isSpinning = false;
},
});
// Add shapes
new Zdog.Ellipse({
addTo: illo,
diameter: 20,
translate: { z: 10 },
stroke: 5,
color: '#636',
});
new Zdog.Rect({
addTo: illo,
width: 20,
height: 20,
translate: { z: -10 },
stroke: 3,
color: '#E62',
fill: true,
});
function animate() {
illo.rotate.y += isSpinning ? 0.03 : 0;
illo.updateRenderGraph();
requestAnimationFrame(animate);
}
animate();
</script>
</body>
</html>
```
### Zdog Shapes
**Basic Shapes:**
```javascript
// Circle
new Zdog.Ellipse({
addTo: illo,
diameter: 80,
stroke: 20,
color: '#636',
});
// Rectangle
new Zdog.Rect({
addTo: illo,
width: 80,
height: 60,
stroke: 10,
color: '#E62',
fill: true,
});
// Rounded Rectangle
new Zdog.RoundedRect({
addTo: illo,
width: 60,
height: 40,
cornerRadius: 10,
stroke: 4,
color: '#C25',
fill: true,
});
// Polygon
new Zdog.Polygon({
addTo: illo,
radius: 40,
sides: 5,
stroke: 8,
color: '#EA0',
fill: true,
});
// Line
new Zdog.Shape({
addTo: illo,
path: [
{ x: -40, y: 0 },
{ x: 40, y: 0 },
],
stroke: 6,
color: '#636',
});
// Bezier Curve
new Zdog.Shape({
addTo: illo,
path: [
{ x: -40, y: -20 },
{
bezier: [
{ x: -40, y: 20 },
{ x: 40, y: 20 },
{ x: 40, y: -20 },
],
},
],
stroke: 4,
color: '#C25',
closed: false,
});
```
### Zdog Groups
Organize shapes into groups for complex models:
```javascript
// Create a group
let head = new Zdog.Group({
addTo: illo,
translate: { y: -40 },
});
// Add shapes to group
new Zdog.Ellipse({
addTo: head,
diameter: 60,
stroke: 30,
color: '#FED',
});
// Eyes
new 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 },
});
// Mouth
new 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 group
head.rotate.y = Math.PI / 4;
```
### Zdog Animation
```javascript
// Continuous rotation
function animate() {
illo.rotate.y += 0.03;
illo.updateRenderGraph();
requestAnimationFrame(animate);
}
animate();
// Bounce animation
let t = 0;
function bounceAnimate() {
t += 0.05;
illo.translate.y = Math.sin(t) * 20;
illo.updateRenderGraph();
requestAnimationFrame(bounceAnimate);
}
bounceAnimate();
// Interactive rotation with easing
let 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();
```

## 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 fallback
const 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 visible
const 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 cleanup
useEffect(() => {
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 changes
illo.updateRenderGraph();
// Ensure canvas has dimensions
<canvas width="240" height="240"></canvas>
// Check shape positions are visible
new 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
// ❌ Wrong
color: "#23153c"
// ✅ Correct
color: 0x23153c
```
