I've been doing this over 35 years and have seven Emmys. They got someone they shouldn't be able to afford and working from home I could afford to accept it. I'm a pancreatic cancer survivor (Whipple) and this flexibility helps. I am a professional. My job is to forecast their weather and I am diligent in that pursuit. Windows are overrated.

In response to Lane -- Pancreatic cancer is the worst. It is incurable in 2018! I was very lucky that it was found before it spread. It was removed in a six hour, two surgeon operation called a Whipple. It was pioneered in the 1930s. Back then they lost about 1/3 on the table. Only about 1/3 of pancreatic patients can receive a Whipple and only about a third of those have my result. Only 9% live beyond five years. Th…

This is scarily close to realistic... for a second I got worried because my intuitive brain was telling me my laptop screen was all wet! Curious if this is the best done in WebGL to date, or if there's even better out there? Or what this does and doesn't do, and where next obvious areas for improvement would be?

(Author here) Thanks! I was making a version with a better "impact" effect and better "trails", which are the weakest parts currently in my opinion, as well as making the larger raindrops sharper—they get a bit blurry right now. I haven't had the time/will to finish it though!

Your location is embedded in the photos you shared on drive. Scarlett Irvine.

OK. I can put on coffee.

Seriously, I was on TV in Connecticut for nearly 30 years. Where I lived was common knowledge. I'd often meet someone whose friend had told them I lived in their neighborhood.

Only once did someone knock on my door just to say hello. Most people are respectful and there are dozens of other clues to where I live since I run a business there.

I appreciate your concern, really.

I am a meteorologist on TV. I work in front of a chroma key wall. I would love to have a simulator like this where I could swap in the background image... well, you get the idea. This would especially be good for me as I do the weather in Nebraska from a studio I built at home in SoCal. As far as I know I'm the only regularly scheduled TV news anchor to work from home in the US and possibly the world.

Do the people in Nebraska know you’re in California? Is that disclosed or simply not mentioned, hoping nobody catches on?

Do you have any problems with this remote setup like Sinclair has with “Centralcasting” local news from far away? (Graphics and visuals for the wrong station showing up, talent’s obvious lack of knowledge of local events and terminology, etc...)

What happens in the event of a California-centric disaster like an earthquake or wildfire, and you’re not available? Or if there’s a major weather event in Nebraska and you’re not there, or not able to feed into Nebraska because Vyvx/internet goes down or the satellite dish freezes over?

Is there any description or attribution for the shader? Are the visuals an improved version of Martijn Steinrucken's "Drive Home" shader [1], or a different approach? This one does seem more dynamic with more detail, it looks pretty good, and I like how the big drops take out the small spray.

This is not a single shader, the animation is done with JS/canvas 2d, the shader does just the refraction.

I wrote an article about it here[1], but I made this back when I was first learning WebGL (it was my first WebGL project, in fact), so be aware that a lot of things could be better!

The fact that we need GoFundMe campaigns for people who get sick or that veterans beg for charity through Wounded Warriors upsets me to no end. A modern, successful democracy should take care of its people.

Hey, I made this for Codrops, like 2 or 3 years ago? I mean, the rain effect itself, not the whole UI around it here. Edit: Here's[1] the accompanying article, and here's[2] some other stuff I made (although my website is also just as old and hasn't been updated since!) [1] http://tympanus.net/codrops/rain-water-effect-experiments/ [2] http://lbebber.github.io/

I don't know why this isn't getting more attention/comment (someone else independently posted it looked similar below with another link to your domain) but here's the one I found from your profile link for comparison http://tympanus.net/Development/RainEffect/

Hah.

Thank you for finding that.

Welp. It's identical. I even tried to defend the current link with "Well, some cool things can happen when you hook up a UI to a shader..." but the UI doesn't even do anything except turn the rain off and on.

There's lightning too in that other one! That's so cool.

Holy crap how many questions are you going to ask?

I came thinking that it was a visual rain simulator. Then I saw a very nice visual display, but the sliders didn't do anything. Then I realized that it is an audio simulator with different audio parameters for the various aspects of the rain soundscape. I'd love sliders for the visual display too. Very nice. Very very nice. Bookmarked.

You can control the number of drops in the animation by clicking on the hamburger menu in the top-right.

Thanks! Didn't find that.

One problem with simulation is that it's super resource intensive, particularly more than a video. It turns my laptop's fans on quickly which then fights for my attention with the relaxing audio and makes me acutely aware that I'm killing my battery and putting unnecessary load on my computer. Maybe a better middleground is to use an animation with transparency that you can instead overlay any background, like a loop…

This has not been done in the most optimal way—it could do with a lot less JS being used. A version with (mostly) WebGL could be much less resource hungry.

Try this version for comparison: https://codepen.io/stefanweck/pen/Vbgeax
