Pickover attractor 10 mln vertices 30 FPS

[Borivoj07]

Hi! I'm trying to create something similar to this video so.. How have you created those fractals? I mean it look really super sharp.

@Borivoj07 That's regular strange attractor. To make this effect find in web appropiate iterate equations and calculate positions of each particle.

[Borivoj07]

@Kwazar90 Well, I've got code that generates typical strange (Pickford) attractor pixel by pixel. But even I've tried some antialiasing, my pictures don't look as good as yours. Are you using some supersapling or something like that?

Another thing is.. Don't you have any clue how to choose parameters (A,B,C,D)? Thanx!

[Kwazar90]

@Borivoj07 You mean your pickover is noised( you can see particles in cloud )?

I'm don't using any postprocessing like bloom. Point is to render a lot of particles, like 10 mln, that count guarantees you nice smooth attractor.

Parameter and equations you can get from chaoscope site in tab "Manual".

@Kwazar90 Jop!

Then I've to say just "woow!" When I try to render about 1 million of pixels, ti looks like my pickford is colored just by one color.. :-D Maybe it's just about the resolution. What is your native resolution of the picture? My is 640x480..

I know this site. I'm trying to find some function which will produce parameters but.. My problem is that time to time my function generates parameters which produce just black screen..

[Kwazar90]

@Borivoj07 Try to minimalize colour saturation to for example [6,4,4].

My attractors were rendered in 2048x1536 and resized back to 640x480.

[Borivoj07]

@Kwazar90 Why to minimize it? I'm sorry for those silly questions, but I'm just beginner in graphics.

Almost the same like me.. I'm in a rush (so many things to school must be done) so I'll have to leave it unfinished for now.. Thank you for answering my questions and here are my two days of life.. :-D

[Kwazar90]

@Borivoj07 In high resolution you can put more particles without burning effect ( honestly I don't know how I could name it in english, I mean effect when you expose your camera on too much light )

You can keep it in that high res but it's realy heavy( my one frame takes 1-2mb ).

Your attractor looks nice too.

sweeeeeeeeeeeeeet

These attractors can be rendered in realtime on a GPU quite easily at maybe a 0.1 this resolution. A PS3 could handle this in realtime.

[parkerault]

Kwazar90, is this a real-time render?

[Kwazar90]

This animation have been rendering two hours, so definitely it isn't real time ;)

Wow, that was beautiful :)

I wonder if solar flairs could be modelled as evoloving strange attractors.
