i know who you are
Chaotic, not random.

How do I into this?

Fuck off, Joe.

>learn programming language
>fuck around with its random class
>>45152233
so i.e. png header and then a shitload of random bytes?

I fucking hate you Andy
>>45152171
I'll throw in some perlin noise I've been playing with.

Hi brother

hahaha so funny guys +1
>>45152254
completely random will just create boring static, you need to influence the seed with an algorithm
>>45152226
are you from canada?? cos if so i think i know you
>>45152261
what the living fuck, nigger?
the simplest algorithm creates the best art
>>45152342
as in im joe and ive been making random images, not op though

math.log is one hell of a drug.
What language are you using for these?
>>45152680
I'm using .net's random-class.
>>45152269
This is beautiful, mind throwing up a pastebin of the source?
>>45153532
sure, http://pastebin.com/6xxhvZMN
>>45152670
Ah, source for this one? Algorithm?
>>45154125
cos(x) + sin(y)
Its a bug, but looks cool anyway.
this stuff is neat. could anyone briefly summarize how these are rendered?
>>45155364
Basically iterate through every pixel, and call a function to set it's colour, then save it to an image.
>>45153655
has a pastebin with some JS if you want to see how he does it.
>>45152171
>sudo chmod 777 /dev/fb0
>cat /dev/urandom > /dev/fb0
can't get more random generated than that
>>45152254
Thats not how PNG files work.
>>45155654
>PNG
>not glorified 24BPP BMP
How do you guys do this?
Like i no how to generate randomnes but how do you do it so that it has some cool pattern to it?
>>45155668
be at least as non-retarded as the average MENSA member and it'll all click
otherwise kill yourself
>>45155660
PNG's are loslessly compressed you fucking idiot.
>>45155679
PNGs cant be mapped to graphics devices you fucking imbicile
you should be fucking ashamed of yourself
>>45155690
>PNGs cant be mapped to graphics devices you fucking imbicile
When the fuck did i say that they could?
Ofcourse they can't.
Hey, awesome! I was just stopping by to ask the Stupid Questions Thread how to create an image from an algorithm.
So, how are these made? (The non-random ones specifically; I'm trying to find a way to create a batch of images from some passed flags; I'm creating video title screens for a bunch of videos, and manually creating the pics is a pain)
Thanks!
This is an algorithm-generated image
What library are you guys using the output the images?
Are you just writing to bitmaps and converting them to png?
>>45155895
>>45155601 is done using .net's system.drawing.bitmap class
How about some fractals.
Here's a Mandelbar fractal I made a while back.
>>45155921
Fractals are faggot shit
This guy has some neat imagery

I think these would look a lot nicer with anti-alliacing
>>45155736
post source code?
>>45156578
proprietary, patented by Time Warner
>>45152261
I didn't even need to zoom to hear that, my monitor immediately made a 10db noise when I opened it
what the shit
>>45152261
didn't do shit
>mfw monitor is invincible
It's like Earthbound backgrounds.

is this the commet landing?

No, that one failed

Andy Warhol would be proud anon
>>45152261
does this only work against IPS plebs?
I didn't hear shit
hello /g/, http://sourceforge.net/projects/imgfun/ creator here, i think i will try OpenCL.NET or multithreading today when i come home and alao get rid of proprietary math interpreter and compile C# code on the fly and use it to computevalues, also, maybe try to use ffmpeg to create webms
>>45156794
What the actual fuck are you on about
>>45156794
.net 5 will add simd, maybe that will be interesting.
>>45156802
cool
last time i tried OpenCL.NET it crashed my gpu driver and went slower then on cpu
i need to learn to write those kernel files
>>45156802
oh so this simd thing automagicaly does math on multicores cool
i found something called Yeeep! and i think i will use it because graphs looked good
>>45156714
this is an amazing wallpaper
Are you guys using OpenGL
>>45156957
maybe, why do you ask?
>>45156714
Sadly I've forgotten how I generated it. Otherwise I'd generate a higher res one. It was a rather complicated input...
It seems I have made a cloud texture generator
>>45155939
Awesome, thanks!

how do i into this shit with C

Oh god what would that do

Allow anyone to write onto framebuffer and write random colors onto your framebuffer (kind of a graphics buffer in linux, when doing console stuff).

Chaos-Game.
I made an interactive version with c++/sfml. It was pretty easy to implement.
>>45152261
The joke's on you, my IPS monitor already makes noises when there's (nearly) full screen black text on white background (e.g. Wikipedia articles).
>>45159113
Welp, trying that on a VM
>>45152261
Depends if your monitor has coil whine or not.
Mine is nice and silent! :P
Here is a program I made to generate images like this.
https://github.com/diantahoc/RandomIG
Don't remember the algos for these, the third one might be X ^ Y or X | Y
I just remembered I made a bunch of gifs as well and uploaded them on my imgur.
4chan thinks half of them have 'malicious code' in them
>>45159392
Scratch that, about 99% of them
>>45155731
Loop through every pixel and define a new random class each time, and give it a custom seed involving a mathematical formula including the x and y coordinates in some way.
This way you influence the choice of pixelcolor depending on the pixels location.
>>45159308
how do I make the program understand formulas input from strings?
>>45159314
Looks like y * x
>>45159358
Did you make that? If not I think I made it.
>>45159392
You generated viruses anon.
yay this threads' still going :D
