so.. what do you all know about these things? caus i just heared i had to make a math essay about this... so im flipping out atm help me please ! |
||||||||
|
|
|||||||||
| |||||||||
|
|
they make cool screensavers |
||||||||
|
|
|||||||||
| |||||||||
|
|
just check some fractal programs and play around with the setting and see what that does...it'll probably give you an idea how they work |
||||||||
|
|
|||||||||
| |||||||||
|
|
You're in luck. I'm studying for one of my MSc Virtual Environments exams which includes fractals. I'll send you all my material when I sort my papers out. |
||||||||
|
|
|||||||||
| |||||||||
|
|
warning there will be much maths involved... |
||||||||

OK, My notes are a fucking mess so I advise you to go to you local library and get hold of a copy of "Computer Graphics: Principles and Practice 2nd edition in C" by Foley,van Dam,Feiner and Hughes. (Addison Wesley). Chapter 20 has a fairly good section on fractals. Otherwise you could always check "3D Computer Graphics, 3rd. Ed." by A.H.Watt or "Procedural Elements for Computer Graphics" by D.F.Rogers. If you're really desperate I can scan the appropriate sections from these texts and email them to you. Let me know. |

Fractals in my opinion are amazing.....I used to have software that creates them. |
||||||||
|
|
|||||||||
| |||||||||
|
|
i have a nice little freeware program, wait a sec i'll upload it |
||||||||
|

right click save |
||||||||

Ok I've located some material that maybe be useful (Mandelbrot Sets and so on). I'm not sure what kind of depth you require for this essay but this should be enough (University level graphics course) |
||||||||
|

Your email address doesn't work. Where can I send the scans? |

hi.. thanks loads! its gonna be a study of about 6 pages or something, ive found some info on the internet.. but it aint helping me much uuhm vaagisdecrew@hotmail.com should be working... else try rombouts@kabelfoon.nl if it screws up.. |
||||||||
|
|
|||||||||
| |||||||||
|
|
oh and cheffe, thank you so much for that program, i tried 3 others but they all fucked up... you guys are great |
||||||||
|
|
|||||||||
| |||||||||
|
|
ohhh shit that program rocks...thanks Cheffe |
||||||||
|
|
|||||||||
| |||||||||
|
|
done |
||||||||
|
|
|||||||||

I've linked to that xaos before, but you might like to check out the home page for it |
||||||||
|
|
|||||||||
| |||||||||
|
|
yes, i found it following your link the other day |
||||||||
|
|
|||||||||
| |||||||||
|
|
Let me know when you recieve it as my email is playing silly buggers with me this morning. |
||||||||
|
|
|||||||||
| |||||||||
|
|
specta-woozie-tacular! this'll help me out... |
||||||||
|
|
|||||||||
| |||||||||
|
|
yeah i got it... those fuckers at hotmail rejected it caus it was too big :S |
||||||||
|
|
|||||||||

|

It's pretty simplistic. If you need more indepth material like research papers and so on I'll contact my lecturer Prof. Forest (He's one of the big names in the field of computational geometry). |
||||||||
|
|

| |||||||||
|
|
heh no im not at uni or something.. we're talking about an assingnment for 16 yr olds (dunno how the school system works in the uk...what grade that is and all) |
||||||||
|
|
|||||||||
| |||||||||
|
|
the entire universe is an infinitely complex multidimensional fractal. |
||||||||
|

hehehe....tweede fase zeker? dat suckte :\ |

All I know is that there was a documentary on quite a while ago about fractals, and David Gilmore did the soundtrack. There were a few interviews with scientific mumbo jumbo, but most of the time they showed these fractals evolving with this cool music. I was with a bunch of friends, and we got stoned and absolutely loved it. |

Ceri JC is the KING o fractals........i'm sure when he see's this topic he'll have lots of good advice. the desktops he's made are fantastic!! *check the DESKTOP thread for examples* |

Fractals are only a simple way to arrange geometric shapes, according to scaling symmetry. The idea was created for math purposes because before it was seemingly difficult to describe the structure nature is composed in using simple, or regular math, traditional math I guess. But mandelbrot and probably others realized that nature often seems to compose itself in nested patterns. For example if you cut a secondary branch, or a branch off of this off of a tree and stand it upright in the ground, it often looks just like a typical tree (except for, say the leaves, which is a reminder that probably no fractals nest forever), only smaller. All you have to remember is scaling symmetry, symmetry alone is interesting to read about too. Take a triangle, shrink it by some percent of the original, and paste it to each side, repeat with the smaller versions, repeat repeat. There is some really complex weird fractal art that uses some sort of equation to compute the visual data or something. I'm not quite sure how that works, but it's works in a similar way. |

they are fuckin' great. i love artwork made with fractals. i love downloading fractal software. music can also be fractal. |
||||||||
|
|
|||||||||
| |||||||||
|
|
also attributed to fractals in infinite circumfrence or surface area. like an ocean-side coast. |
||||||||
|
|
|||||||||
| |||||||||
|
|
Why are they called fractals? |
||||||||
|
|
|||||||||
| |||||||||
|
|
because they represent fractionally dimensional equations. like 1 and a half dimensions |
||||||||
|
|
|||||||||
| |||||||||
|
|
One and a half?! You mean like a line, except kinda thick? |
||||||||
|
|
|||||||||
| |||||||||
|

fractals = boring techno cover artwork for when they can't think of anything actually artistic to put on. and yes, i "get" the very thin concept behind it. it just looks dumb. |
||||||||
|
|
|||||||||
| |||||||||

You can't exactly picture it, because human brains work in 3 dimensions. That's why fractals are such a relatively new thing (first worked out in the 60's or 70's or somethin'). But with elementary particles, like bosons, fermions, etc. particles can have a fractional 'spin' of say, one and a half. Meaning, you have to rotate it one and a half times before it is back to how it was before. |
||||||||

|
|
It's great. You are made out of math. |
||||||||
|
|
|||||||||
| |||||||||
|
|
2.72 dimensions! oooooh spooky! |
||||||||
|
|
|||||||||
| |||||||||
|
|
yes, i know... but this aspect of things bores me terribly. |
||||||||
|
|
|||||||||
| |||||||||
|
|
Also, you have no friends. |
||||||||
|
|
|||||||||
| |||||||||
|
|
Saying we are made of math is like saying the continents are made of geology textbooks. |
||||||||
|
|
|||||||||
| |||||||||
|
|
Hmm... You boggle me. |
||||||||
|
|
|||||||||
| |||||||||
|
|
You look like a nice respectable old lady though. Maybe your words do have some merit... |
||||||||
|
|
|||||||||
| |||||||||
|
|
i disagree with fleetmouse. but fractals still look retarded. |
||||||||
|
|
|||||||||
| |||||||||
|
|
Again, you have no friends. |
||||||||
|
|
|||||||||
| |||||||||
|
|
well, i'd rather have no friends than stare at fractals all day, so there ya go. |
||||||||
|
|
|||||||||
| |||||||||
|
|
only thing it's good for is to make hippy posters from spencer's out of. with a big ol' badly drawn alien head smoking a splif. |
||||||||
|
|
|||||||||
| |||||||||
|
|
I never look at fractals, and I'm not a pot smoker. I just find it intriguing that if you take hallucinogenic drugs, you can see fractals, which I've seen for myself. |
||||||||
|
|
|||||||||
| |||||||||
|
|
just search for chaos info. and things like basic chaotic equations |
||||||||
|
|
|||||||||
| |||||||||
|
|
nah, you're wrong with the spin thingy that has nothing to do with that. the fractal dimension is something like the 'density' of points belonging to the fractal in a space of the next higher dimension, let's say you have a 2 dimensional fractal, then 1.9 says that it almost covers the plane. |
||||||||
|
|
|||||||||
| |||||||||
|
|
its got something to do with self-similarity, but i think when im gonna say this ill make misstakes so just read when your interested |
||||||||
|
|
|||||||||

The maths is relatively simple if you're comfortable with reiteration. Of course you can do some pretty hardcore maths on them but to get them isn't too hard.. I'd suggest you start looking at straightforward fractals like Sierpinski's Triangle. The mandlebrot set is an iteration on the complex plane. Basically you take a point in the C-plane, iterate with the proper equation and colour that point depending on it's behaviour as you take the iteration to infininty. If the point goes to zero in the limit you colour it black, else you colour it according to how quickly it goes to infinity (the colour scheme is arbitrary). I wanted to do my maths honours on fractal geometry but apparently mathematicians aren't very interested in it anymore and hence aren't interested in supervising hnrs theses on the topic.... |
