I'm working on making a #threejs library for my #volumetric #raymarching shader, like the one I put out for three-hex-tiling

Lots of params to tune to make a good variety of effects, but should be easy to drop in to projects since it's a standalone screen-space post-processing effect

Screen recording of a demo web app I created for my volumetric raymarching shader. It shows a layer of white and gray clouds, viewed from above. There is a config pane on the right with a variety of sliders for configuring the shader. Throughout the video, options are changed in the config panel which results in the clouds looking different. They become more wispy/sparse, get larger/smaller, change color, etc.

Working on my #volumetric shader for #threejs in #webgl which now can make some pretty cool looking clouds. All derived from sampling a 64x64x64 3D white noise texture

It's not actually doing any lighting currently; the color is derived solely from density

Perf is OK but needs a bit of improvement; I have some ideas for that

Recording of a browser window showing a scene above some volumetric clouds with a bright blue partly cloudly skybox above. The clouds are moving across the scene as if being blown by the wind. The clouds have light parts on top as if lit by sunlight with darker patches on the sides and lower down. There are some hovering dark stone-like pylons around the scene as well.

I've been very busy in recent months with irl stuff (attending three weddings and a vacation), but I'm still around the Fediverse!

In the time I do find, I've been experimenting with #volumetric rendering with #raymarching

I've cobbled together bits of like 3 different Shadertoy demos and have some semi-decent-looking, light-responsive, volumetric fog rendering in #threejs

Lots of cool tricks involved to get it running anywhere near performantly

Screen recording of volumetric fog demo running in a browser tab. There is a first-person display of a scene that I'm moving around and looking around within. There's a solid platform with some patchy white fog slowly moving across it. There's a highlighted pink patch from an invisible light, and the light is moving over time.

OK this is seriously interesting:
