Adding Three.js Post-Processing To A Verge 3D App

Hi,
I have been busy researching many ways to add custom post-processing filters to my app.
I’ve finally come to think that instead of using other libraries to overlay and process what is going on in my index.html Verge3D ‘container’ div, that it would be prudent to just perform these effects right in three.js.

The first test I’ll be exploring will be using this tutorial to see if i can implement it into a fresh Verge3D project.
3D Batman Logo with Volumetric Light | Three.js Tutorial
this uses a preset three.js post-processing library found here…(huge)
.. A post processing library that provides the means to implement image filter effects for three.js.

Now, it comes to obviously exploring the “do’s and don’ts” of how to implement this.

The first thing i’d like to know is this:
Can I simply link these libraries and alter the app’s .js code (in run your own code section)…
or do i have to alter the actual v3d.js code to implement?
If so, will this have to be re-applied upon Verge3D version updates?

I’m wondering this because in the tutorial, the instructor changes the renderer to the “composer” renderer for the post-processing to operate.

FYI, I’ve always been more of a ‘cobbler’, cutting and pasting and augmenting code to my own liking rather than a straight up ‘programmer’.
I’ve had a steady amount of success with this, as I eventually end up with code of my own and I don’t stop until I have acceptable desired results .
Because i know anything is possible nowadays.

Hopefully I can get these filter effects ideas, which I’ve had on the back-burner for so long, into the rendered result and move on to the other giant hurdles this project demands.

Thanks!
