What problem does it solve? Building high-performance 2D graphics in the browser is difficult with plain Canvas2D, which struggles to render thousands of sprites at 60 FPS. This Skill provides complete guidance for using PixiJS to render interactive 2D graphics, particle effects, and sprite animations with WebGL/WebGPU acceleration. ## Core Features & Use Cases - High-Performance Rendering: Render up to 100,000+ sprites at 60 FPS using ParticleContainer, object pooling, and culling optimizations. - Visual Effects & Filters: Apply built-in filters (blur, displacement, color matrix, noise) or write custom GLSL shader filters for advanced effects. - Particle System Generation: Use the included particle_builder.py script to generate ready-to-run HTML particle demos (fountain, fire, snow, explosion, starfield). - Use Case: Build a 2D game HUD overlay on a Three.js 3D scene, or create an interactive data visualization with thousands of animated data points. ## Quick Start Ask the AI to create a PixiJS particle fountain effect with 5000 particles using the particle builder script.
