A post processing library for three.js that adds fullscreen image effects like bloom to WebGL scenes via passes and effects managed by an EffectComposer. It is a JavaScript library distributed on npm with three.js as a peer dependency.

Use cases

• add bloom and other image effects to a three.js scene
• render fullscreen post-processing passes in WebGL
• apply 2D filter effects over 3D renders in the browser
• set up an effect composer pipeline for real-time graphics
• improve visual quality of three.js demos and games

When to choose

• you are building a three.js WebGL application and want high-quality post-processing effects
• you need a maintained, well-documented effect composer with modular passes and effects
• you want automatic linear color space workflow support in your rendering pipeline

When to avoid

• you are not using three.js or WebGL for rendering
• you need post-processing for a non-JavaScript engine like Unity or Unreal
• you only need simple static image filtering outside of real-time rendering
