Deep dive

Technical Implementation

This is a creative animation work based on HTML5 Canvas, demonstrating the powerful capabilities of Canvas 2D API in creating dynamic visual effects.

Core Technical Features

  • Canvas 2D API: Using native Canvas for graphics rendering
  • Animation Loop: requestAnimationFrame for smooth animations
  • Mathematical Calculations: Trigonometric functions and geometric algorithms for visual effects
  • Interactive Control: Mouse/touch events interacting with Canvas elements

Technical Highlights

The work demonstrates Canvas flexibility in creating custom animations and interactive effects, achieving unique visual experiences through JavaScript mathematical calculations and Canvas drawing capabilities.

Reuse steps

  1. 1Create Canvas element and get 2D drawing context
  2. 2Design animation algorithms and mathematical formulas
  3. 3Implement requestAnimationFrame animation loop
  4. 4Add user interaction event listeners
  5. 5Optimize drawing performance and memory usage

Performance notes

Use clearRect() to clear canvas instead of recreating; avoid creating new objects in animation loops; properly use Canvas caching techniques; pay attention to Canvas pixel ratio on high-resolution screens
