SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill simplifies applying advanced post-processing effects to Three.js scenes using an extensible, composable pipeline based on EffectComposer. It abstracts away boilerplate passes (RenderPass, Bloom, DOF, color grading, vignette, FXAA/SMAA) and enables rapid experimentation with screen-space effects.

Core Features & Use Cases

  • EffectComposer-based workflow: Chain multiple passes (RenderPass, UnrealBloomPass, DOF, ColorCorrection, Vignette, FXAA/SMAA) to create rich visuals.
  • Real-time shader passes: Integrate custom ShaderPass for unique looks and color grading.
  • Common use cases: Add glow with bloom, simulate depth of field, apply color grading, anti-aliasing, and stylized post-processing for interactive 3D apps.

Quick Start

Install dependencies, initialize a Three.js scene, set up an EffectComposer with a RenderPass and desired passes, and render through the composer in your animation loop.

Frequently Asked Questions about threejs-postprocessing

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I add bloom and depth of field to a Three.js scene?▼

To add bloom and depth of field to a Three.js scene, use EffectComposer to chain RenderPass, UnrealBloomPass, and DOF passes, rendering through the composer in your animation loop.

What is EffectComposer in Three.js post-processing?▼

EffectComposer in Three.js post-processing is an extensible pipeline that chains passes like RenderPass and UnrealBloomPass to apply screen-space effects such as bloom, color grading, and anti-aliasing.

Can I use custom shaders for color grading in Three.js?▼

Yes, you can use custom shaders for color grading in Three.js by integrating a custom ShaderPass into your EffectComposer pipeline, enabling rapid experimentation with unique stylized looks.

How do I handle window resize with Three.js post-processing passes?▼

Handling window resize with Three.js post-processing requires managing the EffectComposer dimensions to ensure screen-space shaders like FXAA, SMAA, and bloom scale correctly across the interactive application viewport.

What is the best way to apply anti-aliasing in Three.js?▼

The best way to apply anti-aliasing in Three.js is adding an FXAA or SMAA ShaderPass to your EffectComposer chain, abstracting boilerplate passes to produce smooth real-time web visuals.
