expr formula and Aizawa Atrractor
I haven't used the expr object for much other than some simple math. I'm stuck on this one and could use some help.
This is the formula for the z coordinate of an Aizawa Attractor. Aizawa is new to me so I thought I'd take a shot at it. Can anyone school me on what I may have done wrong or right in the accompanying patch? Not sure I got the order of operations correct and whether they are written properly in expr.
Here is the source video.
/3 ... float or int? seems ok otherwise.
Thank you Roman! I appreciate your time very much.
I don't see the "d" in the /3d at that link. However, that link was another resource I used and a good one! His Java animation of the attractor is really nice.
i think all of these strange attractors formulas are for normalized ranges so that divisions appearing there should be always be thought of float divisions in computer languages.
it is easy to get confused about this when you later trucate to int anyway (for midi?) but in math there is no "integer division" which is only expressed by a single symbol (/) ... that´s a computer thing. :)
and i believe mr. langford is right, it should be named after him since he invented it - at least as long as noone knows where that other name comes from. :P
build the four wing attractor next, it is great for audio!
Floats - YES!
I made the jump to Jitter yesterday and visualizing the attractor. It's very nice. But I can't seem to find a good way to take a single particle's position and map its xyz coordinates to freq/spatial position/amplitude.
From what I can tell (I am no Jitter expert), there aren't any resources explaining how to map the coordinates of a graphical object in jit.window to audio.
i did not want to add this in the other post (==not answering a question other than like it was asked), but if i was you, i would do the attractor in MAX or [gen] and then derive both the graphics and the audio from the data rate numbers.
you can not build them in MSP and even in [gen~] it is a bit complicated to get all those feedbackloops right.
Thanks Roman!! That idea was floating around in my mind so I'm glad you mentioned it. I'll try this later today.
Wow! Ha!! Those are beautiful! I have been sifting through these:

Just a quick note: quite a number of the Meier site attractors are available as Gen abstractions distributed with the GO book, by the way....
