name: pixijs-core-concepts description: "Use for PixiJS v8 renderer concepts: Application/Renderer relationship, WebGL/WebGPU/Canvas selection, render loop, systems, pipes, environment adapters, renderer fallback." license: MIT

Use this for renderer-level understanding before debugging low-level render behavior.

Model

• Application owns the high-level app lifecycle; the renderer draws the stage into a canvas.
• PixiJS can use WebGL, WebGPU, or Canvas fallback depending on build, options, and environment.
• The render loop is usually driven by the ticker plugin, but rendering can be manual.
• Renderer systems and pipes handle specialized work such as textures, batches, masks, filters, and extraction.
• Environment adapters decide how browser, worker, or headless primitives are provided.

Deep Reads

• Renderer selection and renderer classes: references/renderers.md
• Render-loop behavior: references/render-loop.md
• Expanded entrypoint notes: references/details.md
• Application lifecycle: pixijs-application
• Custom systems/shaders: pixijs-custom-rendering

Common Fixes

• Need normal app setup: use pixijs-application first.
• Manual render loop conflicts with ticker: decide who owns render timing.
• Backend-specific issue: identify WebGL vs WebGPU vs Canvas before patching.
