Congrats to the 2025 #NobelPrize laureates in chemistry.
Here are some #molstar renderings of an AgFe mixed metal Metal Organic Framework to celebrate.

A few notes on integrating SSGI into Mol*.

For tracing in screen-space we need to recover thickness.
Want it automatic, not fiddle with parameters.
Insight: Molecules are shown with visuals of very different density.
So we do 2 things
1) Base thickness from front- and back-face depth
2) Density factor to adjust for each type of visual

Inputs are rendered by the same shader code as the standard rendering. There are just two extra output targets: normal + emissive strength and diffuse + density. Additionally we do a pass to get back face depth.

Main idea is to treat the SSGI as a progressive enhancement of sorts. Try to reuse as many of the passes used for normal rendering. And keep the overall look as similar as possible.

High quality lighting from "path-traced" screen-space global illumination. Even works with only emissive lights.
