# PixiJS 2D Rendering Skill

Fast, lightweight 2D rendering engine for creating interactive graphics, particle effects, and canvas-based applications using WebGL/WebGPU.

---

## When to Use This Skill

Trigger this skill when you encounter:
- "Create 2D particle effects" or "animated particles"
- "2D sprite animation" or "sprite sheet handling"
- "Interactive canvas graphics" or "2D game"
- "UI overlays on 3D scenes" or "HUD layer"
- "Draw shapes programmatically" or "vector graphics API"
- "Optimize rendering performance" or "thousands of sprites"
- "Apply visual filters" or "blur/displacement effects"
- "Lightweight 2D engine" or "alternative to Canvas2D"

**Use PixiJS for**: High-performance 2D rendering (up to 100,000+ sprites), particle systems, interactive UI, 2D games, data visualization with WebGL acceleration.

**Don't use for**: 3D graphics (use Three.js/R3F), simple animations (use Motion/GSAP), basic DOM manipulation.
