Shaping Light – Volumetric Lighting

A deep dive into Volumetric Lighting implemented via Post-Processing leveraging a custom shader with raymarching to create beautiful light and atmospheric effect for your React Three Fiber and Three.js scenes.

Thus, by combining these two seemingly unrelated pieces, that are post-processing and raymarching, in the context of volumetric lighting, I discovered a new set of tricks to complement my shader work, enhance the visual of my scenes, and, more importantly, share with you. The principle remains the same: we introduce a random offset, that we get from a blue noise texture, to each of our rays erasing any visible artifacts like banding and yielding a cleaner result. In this section, I wanted to offer a breakdown of some of my creations that leverage volumetric lighting where it really shines (no pun intended) to bring that same bright atmospheric vibe onto my work.
