HTML5 Canvas Masterclass

HTML5 Canvas 

Explore cutting-edge Canvas techniques with interactive examples, particle systems, image processing, and real-time animations.

Interactive Particle System

Key Features Demonstrated:

  • Interactive particle system with mouse tracking
  • Dynamic connection lines between nearby particles
  • Configurable color schemes and trail effects
  • Object-oriented JavaScript implementation
  • Responsive canvas sizing

Advanced Image Processing

Image Filters

Demonstrates real-time pixel manipulation with various image processing algorithms.

Blend Modes

Shows how to use Canvas' composite operations for advanced blending effects.

Performance Optimization

FPS: 0

FPS: 0

Performance Techniques:

Optimized Approach

  • Uses Path2D objects for shape caching
  • Minimizes state changes
  • Efficient memory usage
  • Maintains stable frame rate

Unoptimized Approach

  • Recreates paths each frame
  • Excessive state changes
  • Higher memory pressure
  • Lower frame rate

Modern Canvas Techniques
