This animation particle text effect creates visually stunning motion graphics using HTML5 Canvas and JavaScript, without requiring Flash or WebGL. The solution leverages bezier curves, tweening, and particle systems to generate dynamic text animations that respond to user interaction.
Core Animation Features
The animation system offers multiple sophisticated text effects:
- Bezier Curve Motion – Text follows smooth bezierCurveTo paths for organic movement
- Circular Effects – Text can animate in full circles or semicircular arcs (upper/lower)
- Line Effects – Straight line animations with corner transitions
- Particle Systems – Text can break into particle clouds that reform
- Interactive Control – OnClick events trigger or pause animations
Technical Implementation
The animation stack combines several powerful JavaScript libraries:
1. RequestAnimationFrame Polyfill
The animation timing uses requestAnimationFrame for optimal performance:
window.requestAnimFrame = (function(){
return window.requestAnimationFrame ||
window.webkitRequestAnimationFrame ||
window.mozRequestAnimationFrame ||
window.oRequestAnimationFrame ||
window.msRequestAnimationFrame ||
function(callback){
window.setTimeout(callback, 1000 / 60);
};
})();
2. Tween.js Animation Engine
This lightweight tweening library provides:
- Optimized Robert Penner easing equations
- Smooth property transitions for position, rotation, scale
- Chainable animation sequences
3. Sparks.js Particle System
The particle effects include:
- 3D particle generation and management
- Physics-based movement patterns
- Customizable particle appearance (size, color, lifespan)
4. Three.js 3D Engine
While primarily using 2D context, the system leverages Three.js for:
- Vector math operations
- Advanced rendering capabilities
- Cross-browser compatibility
Implementation Guide
Basic Setup
To implement the animation text:
- Include jQuery and the required JS libraries
- Create a canvas element with proper dimensions
- Initialize the animation controller
- Define your text content and animation parameters
Customizing Effects
Modify these parameters for different effects:
- Path Type: bezier, circular, or linear
- Duration: Animation length in milliseconds
- Easing: Animation acceleration style
- Particle Density: Number of particles when text dissolves
Performance Optimization
Ensure smooth animations by:
- Using requestAnimationFrame instead of setTimeout
- Limiting simultaneous active particles
- Pre-calculating complex paths
- Implementing object pooling for particles
Browser Compatibility
The solution works across modern browsers including:
- Chrome 50+
- Firefox 45+
- Safari 10+
- Edge 15+
- IE 11 (with polyfills)
For advanced implementations, consider adding WebGL fallbacks for complex particle effects or exploring Three.js’s full 3D capabilities for even more dramatic text animations.
