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/

What’s some good reading for a basic and well-explained entry into GL and shaders. I feel like so many tuts gloss over really important stuff. I’ve never written a shader. As an aside, I’m sorry someone stole this from you and used it unattributed.

This got me started: https://webglfundamentals.org/

You've probably come across it though, as it does seem to gloss over some basic stuff. But it does cover the basics pretty well, just gotta keep an eye for details and seemingly unimportant one-liners that turn out to be fundamental.

It also takes some googling for deeper explanation of some functions, which often result on Stack Overflow answers by the author himself.

Dealing with the WebGL API itself is a bit... let's say tricky, though. But working with shaders for me is a joy.

This also seems promising, though I only skimmed over it: https://thebookofshaders.com/

And also, look into https://shadertoy.com/. Both for using the shaders there as example and as a playground.

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.

(author) Hey, I could help with that. I was beginning to work on a better version of it a while ago, but haven't gotten around finishing it.

I am credited for the "menu code" and "inspiration", though, hahah

But it doesn't matter, I posted the code for it to be used, I'm glad to see it in the wild.

Wounded Warriors and DAV are not about veterans begging for money. They are parasites stretching the definition of a charity to its limit to rake in as much money for the admin staff as possible (60% overhead). Please don't donate to these crooks.

Did not know this, can you share some more info to expose how they are crooks?

this is simply not true.

give.org provides charity information. WV spends just 4% on administrative costs... https://www.give.org/charity-reviews/national/veterans-and-m...

“Crooks” might be more than supported by this, but they do seem to have grown into a group existing for the well-being of staff as much or more than their intended recipients.

Now they do, as a result of significant negative media coverage from a few years ago when their administrative costs reached as much as 90% of their total donation revenue.
