threejs-postprocessing

You add bloom and depth of field to a Three.js scene by configuring an EffectComposer with a chained pipeline of multiple passes, starting with a RenderPass and appending a BloomPass or custom ShaderPass for screen-space effects.

Post-processing in WebGL is the application of screen-space effects to enhance realism. Use it for games, interactive visualizations, and real-time data apps requiring cinematic effects like bloom, vignette, or color grading.

Yes, you can use custom shaders with the Three.js EffectComposer by adding a custom ShaderPass to the pass chain, allowing personalized screen-space effects alongside built-in passes like bloom, depth of field, and FXAA.

Yes, you need Three.js postprocessing modules, a renderer, and a configured pass chain to apply screen-space effects. The pipeline requires at least a RenderPass and an effect pass like BloomPass to function.

The best way to apply color grading and FXAA in Three.js is using an EffectComposer-based pipeline, which centralizes multiple passes to apply these screen-space effects without manual per-frame work.

An EffectComposer pipeline requires multiple passes because post-processing effects are applied sequentially in screen-space. You need a RenderPass to capture the base scene before appending effect passes like bloom, depth of field, or vignette.
