We've also provided an example that shows you the final result of this recipe.
You can view this by opening

in your browser. You will see something similar to the following
screenshot:
In this screenshot, you can see that we've rendered a scene with a large number of
cubes and applied an effect to render it as a series of dots.
How to do it...
Setting up a postprocessing pipeline only takes a couple of small steps:
1. To set up a postprocessing pipeline, we need something called a composer.
We'll use this composer in the
render
loop to create the final output. The
first thing we need for that is a new global variable:
var composer;
2. Next, we need to instantiate a composer as a new instance of
THREE.EffectComposer
:
composer = new THREE.EffectComposer(
renderer );
We pass in
THREE.WebGLRenderer
, which we would normally use to
render the scene.
