All in real-time with everything | else going on in the scene. True masterpiece of modern game | technology. | rhacker wrote: | Pretty cool!. Only one glitchy part, the bottom of the screen | seems to have a few drops that appear and disappear at random, | that's the only thing that took me out of the realism. | donalhunt wrote: | Can't tell the difference between the screen and my window (it's | rainy here today!). Nice! | windock wrote: | Really well done, thank you! | madjam002 wrote: | Beautiful, bookmarking this! | jcun4128 wrote: | Man that's crazy, trying to figure out how you make something | look like glass/water.

This loads really fast and is really smooth. | | I've been using https://mynoise.net/ for years as a paying | customer for this kind of thing and am always happy to see | other movement in this tech. | IvoDankolov wrote: | Lovely effect! Particularly enjoyed how it seems to 'fake' | refraction by sampling higher or lower from the background based | on the drop shape. The trails squishing back into raindrops to | simulate surface tension is also a pretty nice touch, though | perhaps a bit over-exaggerated. | | One caveat is the merging of the drops sometimes looks quite | unnatural, but I'm not sure there's any simple way to represent | that as just a couple of textures and a transformation, as real | drops would have attractive forces on a molecular level pulling | them towards one another once they're bridged, deforming pretty | unevenly. | lbebber wrote: | There was an attempt of making the drops merge more naturally, | but it was affecting the refraction effect, which I deemed was | more important. | | It should be solvable though, I just couldn't get the values | right at the time. | | (Also thanks!) | talolard wrote: | I opened this and said wow out loud. Really cool! | williesleg wrote: | It works about as well as digg. | ibdf wrote: | Looks pretty good, I do see some weird rain drops blinking on the | bottom half of the screen (latest version of Chrome). | anticristi wrote: | Anyone else felt like wiping the screen of their smartphones? | Well done! | lbebber wrote: | Hi, I'm the author of the rain effect (not of the website itself | though). | | You can see the original effect here[1], along with an | explanation here[2]. | | If you like it, you can see a few more effects and experiments on | my portfolio here[3], although it's been a couple of years now | since I've done anything of the sort (that I can post publicly, | that is). | | [1] https://tympanus.net/Development/RainEffect/ | | [2] https://tympanus.net/codrops/2015/11/04/rain-water-effect- | ex... | | [3] http://lbebber.github.io/ | nomel wrote: | That story map is beautiful! | | I have a somewhat unrelated question. Do you ever see the world | moving to rendering content completely on a WebGL canvas, for | better control and with the ability to circumvent ad blockers? | lbebber wrote: | Hmmm I'm not sure if it could be properly used to circumvent | ad blocking, after all the ads will still probably come from | a separate request which one could block. | | However I do see it being used for web apps that prioritise | performance--in terms of providing a smooth experience, | rather than load times. I think Figma already does that | (through emscripten or wasm, I'm not sure); for it to be more | widespread, only the tooling has to catch up (e.g. React | Native). | lbebber wrote: | Also thanks, I'm particularly proud of that map hahah | AndrewStephens wrote: | I agree, that map is amazing. I particularly like the way you | can see exactly where the photos were taken. | lifeisstillgood wrote: | I am totally blown away by this - I just had WebGL pegged as | 'draw shapes on canvas, sometimes with colour'. | | Thank you :-) | dgellow wrote: | You should check https://www.shadertoy.com/, you will be | amazed :) | dave_sid wrote: | Brilliant | dave_sid wrote: | I wish this was what I was doing! | OJFord wrote: | Is the submission actually adding anything of substance to your | work then? It seems basically the same but with a background | image, and parameterisation sliders (that I can't get to work | anyway). | lbebber wrote: | Well it has sound it seems, which might actually be more | important depending on what you're looking for. | ebg13 wrote: | The sliders are for sound, not visual parameters. | | This site just combines the visual effect with some sound | recordings.

Thanks for sharing it! | Sephr wrote: | I ported this effect to Android in a live wallpaper called | Rainpaper[1]. | | [1] https://rainpaper.com | lacoolj wrote: | yo i love everything on codrops especially these. thank you for | sharing with the world :) | _the_inflator wrote: | Cool work, very nice! | | It seems that not all your projects, that are download-able, | are on Github. Why is that? | lbebber wrote: | There's no good reason, to my shame. But now that you | mention, I think I'll get around to it and do it this week. | Might be a good opportunity to round down a few rough edges | here and there as well. | svenfaw wrote: | Very nicely done. It even works fine in IE11! | jeffschofield wrote: | For those that feel inspired, there's a good article by Lucas | Bebber that breaks down how this kind of rain effect can be made | in WebGL here: | | https://tympanus.net/codrops/2015/11/04/rain-water-effect-ex... | lbebber wrote: | Hey, I'm the author--thanks for posting this here. | | The page actually uses the exact same effect, so the article | provides a decent breakdown of how it works, for those | interested. | hombre_fatal wrote: | The drops flicker in OSX Chrome 84 for me. Works in other | browsers. | | Not surprising though. This 2017 Macbook Pro's integrated gfx | (Intel Iris Plus Graphics 640 1536 MB) seems incapable of | rendering any 3D games after 2010 without flickering at some | point. It's one reason I'm still playing Morrowind (2002). | spanhandler wrote: | My 2014's Intel graphics handles games newer than that without | graphical artifacts... Unity games in particular are usually | fine. | | However, if you're already playing Morrowind (or OpenWM) then | you don't really need anything else. | jmkerr wrote: | Same here, Vivaldi is flickering and smooth. Safari works | correctly at a noticeably lower frame rate. | | I have found that Vivaldi uses the Macs Intel GPU, and Safari | is CPU bound. WebGL 2.0 experimental support in Safari doesn't | seem to have any effect. | lbebber wrote: | It _is_ really weird, that didn't use to happen either. Started | happening after some update of either Chrome or macOS, I'm not | certain which. | | In fact I think this is one of the most frustrating things of | working with WebGL (or any of those slightly less common | browser APIs, really), lots of small weird compatibility issues | and instabilities. | mistercow wrote: | The same thing happens for me on my 2018 MBP, whether I turn on | the discrete GPU or not. | weinzierl wrote: | Not sure if it is the original but the source where I first saw | this rain effect was on ShaderToy - The Drive Home by Martijn | Steinrucken aka BigWings[1] | | The accompanying video tutorial[2] is super interesting too as | well as the HN discussion at the time [3]. | | [1] https://www.shadertoy.com/view/MdfBRX | | [2] Link to first part: | https://www.youtube.com/watch?v=eKtsY7hYTPg | | [3] https://news.ycombinator.com/item?id=15564148 | lbebber wrote: | It has already been posted by jeffschofield, but the original | is here[1], along with a brief article breaking down the | effect[2]. | | The one you posted is in many ways nicer though due to it all | being a single shader, however it has the downside of the drops | not interacting with each other. | | [1] https://tympanus.net/Development/RainEffect/ | | [2] https://tympanus.net/codrops/2015/11/04/rain-water-effect- | ex... | weinzierl wrote: | I remember that I have seen that before, but I don't remember | when.
