Post Processing

A post processing library that provides the means to implement image filter effects for three.js.

Installation

This library requires the peer dependency three.

npm install three postprocessing

Usage

Please refer to the usage example of three.js for information about how to setup the renderer, scene and camera.

import { Clock, PerspectiveCamera, Scene, WebGLRenderer } from "three";
import { BloomEffect, EffectComposer, EffectPass, RenderPass } from "postprocessing";

const composer = new EffectComposer(new WebGLRenderer());
const camera = new PerspectiveCamera();
const scene = new Scene();

const effectPass = new EffectPass(camera, new BloomEffect());
effectPass.renderToScreen = true;

composer.addPass(new RenderPass(scene, camera));
composer.addPass(effectPass);

const clock = new Clock();

(function render() {

	requestAnimationFrame(render);
	composer.render(clock.getDelta());

}());

Performance

This library provides an EffectPass which automatically organizes and merges any given combination of effects. This minimizes the amount of render operations and makes it possible to combine many effects without the performance penalties of traditional pass chaining. Additionally, every effect can choose its own blend function from a list of built-in functions.
