Topic: Mandelbrot Rotozoom in 256b

This hallway has been silent for too long.
As you might know I'm a freak when it comes to size optimization. A few people made some Mandelbrot fractals renderer in 256b, but till this day no one managed to squeeze a Mandelbrot renderer and a rotozoom in 256b of javascript.



Do you see any improvement or have some other ridiculous challenges to give me ?

ps: This quickie works best in Opera and IE. Firefox chokes on it

Stunning. Now make it zoom in, instead of zooming out, and infinitely, please.

replace n%3 by 4/n

Ok. Divs and colors? 256b.

FWIW, I improved the script. Now it zoom in and out and features some nice circular patterns at high zoom levels. Although it's possible to gain 7 bytes in Firefox and Opera, and 5 more bytes in Opera, I didn't manage to add color.

I dare you to make one using CSS border slants.

Even though I only have a vague idea about what this is supposed to do, I'm pretty sure it's not working for me. In FF I get nothing (it does seem to be running, since everything else in FF slows down to a crawl, but I get a blank page) and in IE I get very spastic behavior. I think IE is closer to what it is supposed to do, but it seems to be flipping out.

reisio: I might have to average the number of iterations first then use something like marching square/cube to generate the markup with the correct borders. It should take about 1kB.

Suho1004: Sorry. The versions I linked to above work in OP and IE. To see the Firefox friendly versions, add _firefox_friendly just before .htm in the URLs. And yes this is quite CPU intensive.

Ah, much better--at least in Firefox. For some reason, in IE the lines seem to wrap-around, making the image grow and shrink vertically. And this obviously messes up the image itself. Does that make sense? (This is in IE7, by the way.)

It's quite cool in Firefox, though.

Yep in IE6/7 the lines don't wrap with the "firefox friendly" versions. The other version works fine though.

Erm... that's not what I meant... this is really hard to explain. When I open the link above (not the FF friendly link) in IE7, it displays, but the lines seem to wrap randomly in the middle, making the image grow and shrink vertically. In other words, the lines don't go all the way to the end to form a nice box, they seem to wrap at varying points so that one line becomes two (or more, maybe, I don't know) lines. Sometimes the image grows so much vertically that a vertical scrollbar appears. Also, there seem to be a lot of question marks... I don't remember seeing question marks in the FF version, but I could be wrong.

Anyway, I'm probably the only person having this problem. Computers hate me for some reason.

Gotta get to bed. Too tired to think.

that is absolutely amazing!
way to go poi!

I wanna be amazed too! D:

Firefox 2.0.0.1, Ubuntu Edgy.

life: nothing appropriate.

thanks,

rukuartic: See my first reply to Suho1004

So I guess the original version works for everyone else in IE7, huh? I wonder why it doesn't work for me. With the exception of the problem I described above, it seems to run a lot smoother than the FF version.

Btw the problem you described happen every time there is one interation too many, a \n is added, making the lines wrap like at unexpected place. But that doesn't explain why you have that.

note to self: I should really make some sort of browser sniffer ( *shudder* ) for that kind of scripts. Every time, someone complain it doesn't work and fail to read the comments pointing to the version they should use.

well, there is your next challenge: "Mandelbrot Rotozoom in 256b for all Browsers"

poi: I am using the IE7 version... this is the one you originally linked to, right? Why do you keep insinuating that I'm using the wrong version?

But whatever. I'm not trying to bust your balls over this. I'm just saying.

Suho1004: Sorry my previous comment was poorly worded. I wasn't blaming or insinuating anything about you, but noticing out loud that rukuartic missed the post mentioning the firefox friendly versions. The exact same thing happen on Pouet.net ( a demo scene portal ). There, people didn't read the technical discussion and one even thumbed down ( a brilliant c64 coder btw ) the prod directly without giving any chance to solve the problem.

Grumble: Well, I've been in an assembly mood recently. Last WE I made:


Asahikawa - a 64b voxel city landscape.

And this WE I improved my 32b "fire" effect.


32b fire effect .v2 - now without <3 padding, glitches and border


Due to the ridiculous size of these effects, there is no room to add ESC support to exit. You'll have to 'end the task' manually, sorry


Damn, I should really get started on a new JavaScript demo instead.

Grumble: done

niceee....
poi you are truly the master of javascript!!!

those assemblies arent workin for me, btw. just giving me a black screen. you should put them up on pouet if you havent done so already.

Thanks.

I've already submitted the 256b JS Mandelbrot rotozoom and 64b assembly Asahikawa to pouet

Also on my laptop, most DOS prod shows a black screen at first, but if I switch task then switch back to the DOS task and make it fullscreen, it works. Sorry about that. I honestly have no idea why. Add to that that these prods works fine on my work PC. Go figure
