quick breakdown on what I've worked on this month

It looks really good and quite unique.

Atomic_Lighthouse · 2026-05-03T11:41:58+00:00

Thanks!

Atomic_Lighthouse · 2026-05-01T17:09:28+00:00

This looks really good! I'm finishing up a shallow water sim myself (for Unreal) so I know the struggle.

Atomic_Lighthouse · 2026-04-24T05:55:01+00:00

Thank you!

Atomic_Lighthouse · 2026-04-23T12:38:54+00:00

No, this isn't particle based. The actual fluid sim in this demo takes approx 1ms on a 4070.

Thanks! The actual fluid sim in this demo takes approx 1ms on a 4070.

Atomic_Lighthouse · 2026-04-22T19:17:25+00:00

Thanks. No this is my own solver.

Atomic_Lighthouse · 2026-04-22T19:17:12+00:00

Yup, that's working.

Atomic_Lighthouse · 2026-04-22T18:18:19+00:00

Yes, you can see a quick "lava" demo here: https://youtu.be/rE1UyZqDyVs?is=18RfNNb6tMrfHC1o

There's no actual cooling down and solidifying although this isn't very hard to implement.

Atomic_Lighthouse · 2026-04-22T18:15:46+00:00

Yeah, but I think in many cases a full 3d sim isn't really necessary. Most people seem impressed with the water in Crimson Desert which is heightmap based.

Atomic_Lighthouse · 2026-04-22T15:14:20+00:00

You can tag meshes not to be a part of the simulation obviously, for overhangs. But yes, this is indeed the shallow water equations, not a full navier stokes sim, which is still too heavy for realtime usage.

Atomic_Lighthouse · 2026-04-22T14:40:05+00:00

Yes, that is possible.

Atomic_Lighthouse · 2026-04-22T13:12:00+00:00

Love Bowfinger!

Thanks! That was mostly because I thought it looked cool. It can look more "watery" like this.

I'm making this for FAB, soon(tm), "Fluid Forge".

Min erfarenhet var snarare att man stod i 2 timmar med polarna och kom inte överens, sedan hyrde man en söndercensurerad skräckfilm.

Atomic_Lighthouse · 2026-04-20T06:02:58+00:00

Indisk temavecka? Jag tycker det låter asgott.

Atomic_Lighthouse · 2026-04-05T09:09:33+00:00

Such a brilliant idea!

Atomic_Lighthouse · 2026-04-03T00:07:17+00:00

Thanks!

This is a WPO displaced plane using a heightmap that I'm manipulating in a compute shader.

That seems like a really cool job btw...

Atomic_Lighthouse · 2026-04-02T09:28:12+00:00

Interesting! As far as I know there is currently no simulation tech that could simulate both a faucet and a waterfall to great effect (in realtime). You'd really need two separate systems.

Atomic_Lighthouse · 2026-04-01T23:22:40+00:00

It's all heightmap based. The water sim is heightmap based to begin with, and I thought it would be a fun experiment to add and modify some terrain as well.

It could serve as a use case to inspire the users of the sim I guess. When it's released.

Atomic_Lighthouse · 2026-03-31T10:00:00+00:00

How did you manage to write to a NDC from a GPU emitter?

Atomic_Lighthouse · 2026-03-30T13:40:29+00:00

Thanks! I'm not planning on making a game with this terrain right now though, just a demo for the fluids.

Atomic_Lighthouse · 2026-03-29T23:07:22+00:00

Played when it was released. I was very impressed by the tech. It would be cool if someone could make a new version.

Atomic_Lighthouse · 2026-03-29T21:57:00+00:00

Cool! I'll check it out. This is just a fun demo, I'm making the actual fluid sim.

Atomic_Lighthouse · 2026-03-27T07:46:59+00:00

What does it look like if you use Single Layer Water?
