completely random will just create boring static, you need to influence the seed with an algorithm

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

can't get more random generated than that

Thats not how PNG files work.

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

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

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

Are you guys using OpenGL

>>45156957

Sadly I've forgotten how I generated it. Otherwise I'd generate a higher res one. It was a rather complicated input...

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

>>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
