Where are the filters in Three.js?

Question

3D

For a change, I decided to try Threejs and everything seems to be clear, except for the moment with filters.
I can't find how to make the glow. Google says that for this I have to write a thousand lines and a shader with my hands. I don’t want to believe in it, because this is the Middle Ages, that’s why I ask this question - how to make a glow and how are things with filters in general?
For example, I looked at babelon.js, there is also no hint of filters. I have never worked seriously with 3d and maybe I don’t know something?

Answer 1

You need to write a pixel shader (fragment shader). Although a lot of people have probably already written it, google it.

Answer 2

Filters in the world of 3D graphics are called post-processing. Three.js has a lot of ready-made examples, including with a glow, for example this option:
