	Explore the beauty of fractals Lose 30 kilos (of popups)

Hey. This program features some of the most beautiful fractals. It is light (17 KB zipped) and easy to use. All instructions are in readme.txt


Edit: updated - number of iteration control added

Muxec; what threshold did you set for that fractal?

I only ask because a lot of it is black - which usually means the program has skipped a lot of the trickier calculations.

Sorry to rain on your parade - it's quite a good example, just it could be a lot better with a little tweaking...

yeah, higher threshold shouldn't be a problem on nowadays machines... how long have fractal graphics been in existence? must be a child of computer technology, noone would ever draw one

It's generated by upto 256 iterations. It's Z-polynome fractal so it is black.

	Put an end to popups!

Ups.. You were right. It's due to low amount of iterations. I'll upload fixed exe now.

Since the early/mid 80s, at least. Well, for computers, anyway. In the physical world, fractals have been around for a lot longer.

People have drawn fractals, although simpler ones than what computers are capable of.
This looks like a gallery of fractals that were drawn by people.

When it comes to drawing fractals, nothing comes even close to the old but still wonderful DOS program fractint

XaoS, however, is a serious contender if you don't need to define fractal formulas of your own

by drawing fractals I was referring tothings like drawing a mandelbrot set based on the calculation of each dot, which would be impossible to any human being. explains why they've only been around since the mid-80s.

we had fractals at school in computers advanced course. I played around a bit and found strange things. inverted fractals, an inverted parabole fractal, monster like shapes and stuff like that. always based on Mandelbrot and Julia sets, varying the calculation only a bit results in vast changes. that's why it's called chaos

I saw a show in the 80s that was hosted by Arthur C. Clarke and called Fractals - The Colors of Infinity. The program was about fractals and the Mandelbrot set. The graphics which showed off the Mandelbrot set were mind blowing.

Ever since I got online I have been searching for a program to display fractals like I saw in the show, but I've had no luck. I've downloaded numerous programs, but none come close to the graphics used in the show. It astonishes me that 15 years or so later, there is no easily available program to duplicate what I saw.

Either such quality graphics can only be obtained through some kind of commercial software, or they used a super computer back in the 80's, which home pcs cannot yet match.

I wish I knew what software and computer was used in Fractals - The Colors of Infinity.

Actually fractals have been studied since longer than that.
The Koch curve was defined early in the century (they were used as counterexamples for different things).
They became a field of interest by themselves only in th 70s maybe.
BTW things like Mandelbrot sets can be drawn by hand, not by using point by point and iterating, but by proving that certain areas will end up being a certain color....
You wont get the details, but you can get an idea of what the big areas look like...

Dont forget that ppl who actually prove things about fractals, dont just draw them, but most actually theoritically prove theorems about them, drawing only get you so far.

I dont think the answer is computer power, it must be the settings used were very carefully chosen, the colors etc...

The Windows Media Player can be set to display moving geometric and fractal images while playing music. The let down is that the images are not synchronized to the music, still it's kind of fun.
