PixiJS 2D Rendering Engine

PixiJS is an extremely fast, lightweight 2D rendering library that uses WebGL for hardware-accelerated graphics rendering, making it ideal for games, interactive experiences, and rich media applications on the web. Originally created by Mat Groves (GoodBoyDigital) in 2013 and now maintained by the OpenJS Foundation, PixiJS has over 44,000 stars as of 2026. Key features include: WebGL and Canvas2D (automatic detection and fallback between WebGL for maximum performance and Canvas2D for maximum compatibility, with consistent API across both renderers), high-performance rendering (batched sprite rendering with automatic texture atlas packing, capable of rendering tens of thousands of sprites at 60 FPS), display object hierarchy (Container, Sprite, Graphics, Text, Mesh, TilingSprite, NineSlicePlane, and AnimatedSprite with parent-child transformation inheritance), sprite and texture system (from image, spritesheet, render texture, video, and canvas sources, with automatic base texture management and GPU memory cleanup), filters and effects (blur, color matrix, displacement, noise, alpha, convolution, drop shadow, glow, shockwave, and custom GLSL shader filters), masking (graphics masks, sprite masks, and alpha masks for clipping and reveal effects), interaction manager (pointer, mouse, and touch events with hit testing, drag and drop, and custom cursor support), event system (EventEmitter-based event propagation with bubbling and capture phases), ticker and RAF (requestAnimationFrame loop with fixed timestep option, minFPS and maxFPS control, and delta time normalization), resource loader (asset loading with manifest-based preloading, texture compression in Basis, KTX2, DDS, and ASTC formats for GPU-native texture compression), and accessibility (DOM-based accessibility layer for screen reader support with ARIA labels).
