description	Use this skill when understanding how PixiJS v8 renders frames: the systems-and-pipes renderer, the render loop, and how the library adapts to different environments. Covers WebGLRenderer/WebGPURenderer/CanvasRenderer selection, renderer.render() pipeline, environment detection, and pointers to per-topic deep dives. Triggers on: renderer, WebGL, WebGPU, Canvas, render loop, render pipeline, systems, environments, autoDetectRenderer.

Foundational model for how PixiJS v8 gets pixels on the screen: the renderer decides which GPU backend to use, the render loop drives per-frame work, and the environment layer adapts the library to browser, Web Worker, or SSR contexts. For the scene graph itself (Containers, transforms, destroy), see pixijs-scene-core-concepts.

Quick Start

console.log(app.renderer.name); // 'webgl' | 'webgpu' | 'canvas'

app.ticker.add((ticker) => {
  sprite.rotation += 0.01 * ticker.deltaTime;
});

const tex = app.renderer.extract.texture({ target: app.stage });

app..({ : app. });
