Hey folks! If you haven’t seen, or aren’t tuned into the facebook world as much - here’s a link to my online course over at the NODE Institute for creating realtime volumetrics in Touch
Volumetrics in TouchDesigner
This method I teach leverages light COMP’s and the existing TouchDesigner lighting framework very heavily, so it reduces the amount of glsl code you have to write generally when doing work like this and also makes your pbr renders really fit together tightly with your volumetrics.
The other big plus here is that since lighting effects are usually composited as a simple add, this is a very modular pass, you could package it up as a tox with some work and have it in the palette to drop in for fairly quick volumetrics.
Here’s a few examples and stills from a few different scenes I put together using this technique:
