Yes, particle velocity! I believe this clip is after I implemented metaballs too, so the particles blend together to make it feel more fluid-like.

Hey this was also the first fluid sim paper I ever implemented! I haven't done any grid-based simulations (except maybe the classic "Real-Time Fluid Dynamics for Games" by Jos Stam), but I've been able to greatly improve

In skydiving, it isn't unheard of for someone to have their phone fall out of their pocket and survive impact without the screen shattering. That's from ~13000ft, but once the phone reaches terminal velocity, it's all the sam

I recently went this route. I didn’t want to set up or use Unity so I wrote my own 2D fluid simulator based on some of the same papers using Metal compute shaders (though I’d love to try again using webgpu). Sebastian’s video is great and t

Written english is often only a second language for Deaf and hard-of-hearing people. Sign languages have their own idioms, culture, and identity; ASL isn’t signed English. I previously worked at a video relay service company (VRS in the US

The passcode fallback isn't available for passwords, just for unlocking the device. In fact, IIRC I don't think you can set up iCloud Keychain without FaceID being enabled...

There's a conflicting forecast here[0], that says it's decaying. The graphic for the "decaying" forecast says it's a forecast for 10am EDT. The forecast linked in OP says it's for 2am EDT, which is before the p

At my employer we use Objective-C++ to interface with some shared C++ code. Swift can use C directly but it can be useful to wrap a C library in an Obj-C interface to be easier to use in Swift.

At my local drop zone one of our pilots posted this video as a reminder of why we let the pilot know when we have large groups leaving the plane. Large groups outside like this can starve the elevator of airflow, and the sudden change in ce

The page seems to assume that semicolon's keyCode is 59 so the modifier key in the demo only works with Firefox according to this table on MDN[0]. The keyCode for semicolon varies not only by keyboard layout but also by browser. Mine i

I was considering using lib-tex (the library implementing texlive 2019 for this shell) last week for an iOS app I’m working on that needs to generate basic LaTeX images. It’s really impressive, these programs running in A-Shell are modified

I don't think this is true... Apps below iOS 13 won't be able to use the new system-defined UIColors, yes, and users below iOS 13 can't change to the dark-mode using a switch in the Control Center, yes. But you've been a

Phantom types aren't part of the language because they don't need to be. They're just empty types used as type parameters for structs, where the type parameter isn't actually used as a variable in the struct. It is more

I'm loving all the history of the atomic bomb and related articles, but I'm curious. Is this just a trend on HN right now or is something I'm not aware of going on?
