All of reality, from the smallest microcosmic sub-atomic particle, to the largest galactic cluster, seems to follow the same basic fractal structures - structures based on number and dimensions.

How about super-original original content? A few years ago I was messing around with new approaches to visualizing the mandelbrot landscape. I'm just running my program... I don't remember exactly what it is I'm doing here...

I like those a lot. Was this a fully custom software or were you messing with the parameters in an existing program?

>>2402787
No this is written from scratch in Delphi using a lot of assembly code. I spent a lot of time trying to optimize for speed in assembly, and looking for new algorithms to give fast results.

Haven't played with fractals in a long time, this is from 2003

>>2402803
Same area, but using 120 iterations instead of 40. If I remember correctly, these shapes are related to the periodicity of the function, like the paths that the value follows as you keep squaring and adding. My memory is fuzzy though. But that was definitely one of the things I was trying to visualize.

>>2402813
Last one for now, got to get back to work.

I have yet to delve into the realm of writing my own software, I hope to some day. I mainly use fractals mainly as a form of meditation. understanding their relevance and the fractal structure of reality has given me a new perception of the universe.

It frustrates me when people just write them off as little more than pretty pictures.

>>2402833
you want they should be the new religion or somthing?

I know the guy who makes these, he's a pretty cool dude.

i just enrolled in a class on "chaotic dynamics" in the computer science dept and it's basically about fractals. screenshot from 1st homework includes me spelling bifurcation wrong

>>2402833
In college (this was a while ago) my computer would run all nigh calculating the next zoom into the mandelbrot set. Every morning I'd print out the new image and put it all the wall. People looking 30 zooms all printed out up on our wall would be amazed. My roommate and I would joke that the next one would contain the eye of God looking back at us.

itt: drug addicts

first fractal i made. I think it's called a sin map? it looks really 3d even though its 2d

>>2402875
Im not helping the drug accusation here...little drunk

>>2402868
Where can I get a program that does this? I have a quad core so this is something that might be interesting

>>2402885
I'm pretty sure there are programs there are out there you can download. Personally, I've always just programmed my own. It's pretty simple if you have any programming background at all.

>>2402885
just do a google search for "Fractal Extreme" or "Xaos"
those should get you started.

>>2402895
True, but CUDA does it in real time. So, fuck DIY unless it's in CUDA.

Apophysis is good for flame fractals like these.

you don't necessarily need cuda. you can just use shaders to render the fractal on the gpu

>>2402930
So instead of doing GPGPU the easy way, it should be done the hard way...

>>2402930
I use SSE variants to do some limited parallel processing. But GPU's are getting more and more powerful. I should probably learn some GPU programming to take advantage of that.

does anyone have a program to suggest with infinite precision floating point?

I've heard python has it, I don't know how to do it in c, I think it doesn't have infinite, the best you can get is long double.

>>2402930
shit why aren't we using fractal textures in games?

hey assholes, you've got nothing on this:

There are plenty of libraries for arbitrary numbers. C++ has bigint for example. I'm not sure how it looks in C, but it's possible as well.

>>2403122
Not everyone has a couple dozen supercomputers laying about.

>>2403152
I found gmp for c.
But I can't get it to import. It's my first time trying to use a library other than the "normal" ones. i.e. time, stdio, math, etc.
i tried:
#include "path to library"
then
gcc code.c
and it gave me a few errors per line of code in the library.

I tried
#include <gmp.h>
and
gcc code.c
and it gave me a few errors

>>2403518
Heh. Copy-paste first error please.

>>2403518 #include <gmp.h>

This isn't going to load the library unless the folder you stuck gmp.h into is in your compiler's search path.

#include "path to library"
This will work, but is usually bad coding because everyone will have a different directory setup. I'm guessing this worked and the other attempt did not, but there are issues with the library. The library could itself be dependant on other libraries you are missing, using non-standard C-syntax from a different compiler, or dozens of other things.

Is That a Fortran 90 file you're trying to use a C compiler on?

>>2403568
errrr. Yeah. I got it from here:

what should i have gotten?

>>2403558
>/usr/lib/libgmp.so:1: error: stray ‘\177’ in program
Did you type
#include "libgmp.so"
?
Oh lols. That's not how you do it. You never #include a .so file.

You should read some tutorials on header files and shared-objects, aka shared libraries, aka DLLs.

>>2403078
You can find a libraries to handle arbitrary precision floating point for any language. I don't know of any language that handles it natively. I've used Java and c libraries for it. Just realize it's not going to be anywhere near as fast as processor-native floating point.

man when i see these my lips taste like burnt plastic..odd

>>2403568
What? .so is a shared-object suffix, the DLLs of Linux. It could be any variety of file, though if it was randomly obtained, it's likely the result of compiling C source.

Where are all the fractals you tool bags.
