Will this be in the viewport 2.0?

Runs in your browser. Fast and nice. Will these feature be in the compositor or can we see such a fast rendering in the viewport 2.0?

This is not something that would be useful in any case outside of that small demo. It uses precomputed height fields and fakes caustics with a very basic algorithm. Refractions are done with simple ray tracing, and aren’t anything really special in terms of real time rendering.
