I needed again to get an axis-aligned Largest Interior Rectangle, and @jake rice 😮 earlier solution didn’t cut it (too much obvious failure cases, even with @CoskuTurhan modifications), so I did a new one from scratch. It’s based on this algorithm (without the outline optimizations) github.com/lukasalexanderweber/lir

I started with a more-nodes-less-vex approach, so it’s a bit of a weird combination. But seems to work 😉

Hahaha this is a direct copy of the answer Omar gave me when I asked the chances of overshoot when intégrating that function
As for a question whether it will overshoot, It will not as it uses an exponential integrator with the assumption that p and A are static through the timestep: `A(t) = G + (A(0) – G) * e^(-pt)` the pull operation ends up evaluating the `A(t)` `A(0)` would be the current value of the field `G` is the current value of the source `p` is the strength Finally, `t` we are evaluating at is `TimeInc` For `t>0` and `p>0` (which is certainly the case), we can see that `0 < e^(-pt) < 1` , which entails that A(t) will be between A(0) and G

Had a little time this eve to fix some shit and add standard collisions back in

Tidied it up if anyone wants to have a play, probably better ways to set this up but it’s not horribly convoluted (at least by my questionable standards 😂 )

no other engine can do it, so points for that

@tokyomegaplex I’ve been doing this a lot lately

it is a principled shader with no base color, high spec, and low opacity

and a volume rasterizer

you get spec hits, and the white volume look

you’d be able to pump up the spec in comp, this just uses the whitewater particles as is

@nicholas ralabate @jake rice 😮 This is a really stupid example, but it demonstrates the technique nonetheless

Sorry, my discord notifications were off – so I didn’t see this until I switched on my computer

I’m using a complied block in a sop solver and processing both geometry and constraints in the same step – and they work in tandem 🙂
