algorithmic modeling for Rhino
There's a lot of ways to vary the frequency by using the 'right' function inside the sine. Could you draw what you'd like yours to look like.
thanks for the response! something like that (see attached picture)
You didn't find enough !
I joke I add also difficulties finding what I did not so long !!

A variable frequency sinus(f(x)) is quite simple to make, if f(x) is a monotonous function, it just increases or dicreases when x increase. If first derivative is constant, frequency is constant. If derivative changes frequency changes. You could use graph mapper followed by mass addition (same as integral). Example here
wow thanx Laurent! Excellent contribution!
on second thought i think i am doing something wrong. the curve appears to be discontinuous. I used the polyline output from david's part, what am i missing? I am looking for a result exactly like the smooth sine line on the last graph you sent above.
An example smooth
that's great, thank you very much!
