Looking at the example here:

I'm curious if there is a way to perform this post-processing business on a copy of the original data set. In other words, I want to display the original rendering of my scene in one container, and then would like to display the post-processed scene in another container. How is this done?

Thanks!

You can take a look at this example: https://threejs/examples/#webgl_postprocessing_advanced

Generally, you render to a offscreen texture (not to the actual screen) and then use that as input texture for any other effect/primitive/whatever that you need to.
