Perlin noise flames platform :   JavaScript type :   1k release date : november 2010 53 10 0 popularity : 0 %   0.84 alltime top: #1553 [download] [mirrors...] added on the 2010-11-27 by SkyLined   popularity helper increase the popularity of this prod by spreading this URL: comments Generates a pool of randomness, which is used to create one dimentional perlin noise arrays that change fluidly over time. Two perlin noise arrays are used; one as a distortion map, the other as a color map. The size and range of noise of the color map is used to create the look of flames and the size and range of the distortion map is used to make the flames move like flames. The same data is used for flames and smoke, with different color palettes. Two hidden canvasses are used to create the flames and smoke individually, which are combined into a third, visible canvas. Original code size ~10k (with comments and useful variables names). Code size after comment & whitespace removal, variable renaming and various size reduction tricks: ~1.2k. Code size after [ulr=http://code.google.com/p/jssfx/]JsSfx[/url] compress: 992 bytes (this is the JavaScript only and excludes the HTML tags in the final prod).   added on the 2010-11-27 10:40:50 by SkyLined   Doh! JsSfx   added on the 2010-11-27 10:41:44 by SkyLined   This only works with Chrome.   added on the 2010-11-27 10:48:49 by SkyLined   O_O'   added on the 2010-11-27 11:01:21 by panic   Nice and runs fine here.   added on the 2010-11-27 11:04:26 by Zplex   nice, but chrome only...   added on the 2010-11-27 11:08:29 by las   Cool   added on the 2010-11-27 11:14:19 by Mystra   Wow!   added on the 2010-11-27 11:20:56 by D.Fox   Hah. This works in OWB on AmigaOS4. Very slowly, but it works :-)   added on the 2010-11-27 11:25:59 by xeron   It has a nice flowiness to it :)   added on the 2010-11-27 11:30:26 by msqrt   Uh, missed the button I guess.   added on the 2010-11-27 11:31:19 by msqrt   yup, js is getting somewhere :)   added on the 2010-11-27 11:36:55 by hArDy./tRSi   Replace s[ i ].data[x*4+u]=e*n[1]+e*e*n[2]-n[0]; by s[ i ].data[x*4+u]=Math.min(255,Math.max(0,e*n[1]+e*e*n[2]-n[0])); and it will work in ALL browsers. Right now you are going through a crack of the spec. Unfortunately, it's no longer specified what vendors should do with out of bound values. The packers seems to do a good job. I just through the cross browser version through the packer I used/improved for JS1K and got 1017 bytes. I'm sure it can be even smaller with a couple of tweaks.   added on the 2010-11-27 11:50:20 by p01   Skylined: please don't link to a website with the effect, but to an archive (ZIP) of all files needed to run the effect. Otherwise it becomes impossible to maintain a sensible archive over at Scene.org. :)   added on the 2010-11-27 12:02:11 by gloom   s/just through/just threw :p   added on the 2010-11-27 12:44:24 by p01   very pretty   added on the 2010-11-27 12:52:44 by button   nice, but could be more noisy   added on the 2010-11-27 12:59:53 by cruzer   Work in Firefox :) !   added on the 2010-11-27 13:35:57 by XT95^FRq   Nice work. And what XT95 said.   added on the 2010-11-27 13:41:09 by iks   Eyecandy oldschool effet. :) By the way I disagree with XT95.   added on the 2010-11-27 18:30:15 by Zavie   looks quite weird in opera 10.63.   added on the 2010-11-27 18:38:58 by uncle-x   Screenshot looks very nice !   added on the 2010-11-27 18:42:40 by lsl   gorgeous effect! now fix it to work in more browsers like p01 suggested ;)   added on the 2010-11-27 20:29:33 by Weyland Yutani     added on the 2010-11-27 21:25:39 by Alpha C   Nice :)   added on the 2010-11-27 21:28:59 by PauloFalcao   displaying none 25 50 100 all comments (1-25) out of 73 next page   submit changes if this prod is a fake, some info is false or the download link is broken, do not post about it in the comments, it will get lost. instead, post about it. add a comment You need to be logged in to add a comment :: register here
