Screen space reflections? #190
Description
Please consider implementing screen space reflections, it would be an amazing addition to improve Three.js realistic factor.
I've found some good sample, tutorial about SSR:

Thanks for the references. I can't say that I'm a fan of SSR, but I'll consider adding it.

Just wanted to +1 the SSR request

I've found an in-progress working implement for Three.js here: https://github.com/gkjohnson/threejs-sandbox/tree/master/screenSpaceReflectionsPass
The result is lacking blurring by roughness, but it does look very promising.
Maybe you could use it as a base to develop on?
vanruesc commentedon May 21, 2020
Thanks, that implementation does look pretty good 👌 My current plan is to finish the
SSAOEffect, improve theToneMappingEffectand then start working on SSR.gonnavis commentedon Jun 17, 2020
@vanruesc Looking forward to!

I wrote my own and make a pr to three.js, but now just support OrthographicCamera, I'm trying to support PerspectiveCamera.

PerspectiveCamera support is OK now. mrdoob/three.js#20156

Just here to add my +1. I'm currently experimenting with this framework for the company that I work with, and SSR would be quite beneficial!

Hi! This will be super useful! is it currently under development?
vanruesc commentedon Mar 17, 2021
See this comment for the current plans regarding SSR.
I haven't forgotten about it, but it's currently not a great time to use SSR with
three. The point of SSR is to render reflections without having to render the scene multiple times. This is currently not possible becausethreedoesn't support MRT yet. Even if we were to implement SSR right now, we'd still have to render the scene many times to gather the various textures that are required to render the effect. You'd be better off using a CubeCamera or a Reflector.DolphinIQ commentedon May 28, 2021
@vanruesc Hi, youre doing awesome work in this repo! Just wanted to let you know MRT landed in three.js r129! Will this change priority of any features, like SSR?
vanruesc commentedon May 30, 2021
@DolphinIQ Hey, thanks! The priority of SSR doesn't really change, but MRT definitely opens up a path to an efficient implementation. We still need a reliable way to modify three's built-in materials, e.g. via NodeMaterials, to make effective use of this feature. Related comment: #292 (comment).
