Updated Nov 26, 2025

Explain

PixiJS abstracts WebGL rendering into an easy-to-use 2D graphics framework.

Supports sprites, textures, graphics, text, and filters.

Provides animation and ticker systems for smooth updates.

Runs efficiently across devices and browsers with automatic WebGL fallback to Canvas.

Integrates with other libraries like GSAP for advanced animations.

Core Features

Sprites and textures

Graphics primitives (lines, shapes, polygons)

Text and bitmap fonts

Filters and custom shaders

Interaction manager (mouse/touch events)

Basic Concepts Overview

Application - manages renderer, stage, and ticker

Container - groups display objects

Sprite - textured images or animations

Graphics - vector shapes, lines, polygons

Filters - apply visual effects to objects

Project Structure
