Alright - I worked out a new basis for the spiral generation related to these two topics:

http://filterforge.com/forum/read.php?FID=11&TID=9142
and
http://filterforge.com/forum/read.php?FID=18&TID=9133


This new codebase supports two additional output modes: perpendicular gradient and division gradient. However it is not 100% complete yet and I need input from someone else.

There are two problems:

Output mode 1 is not correct - there is a very annoying split. Ideally this mode will index each "arm" with respect the given Division setting.

Output mode 2 is not always in 0..1 range, and the gradient is not perfectly perpendicular to mode 3.


All comments are welcome smile:-)

"Pics or it didn't happen!!"... ok then (Divide = 3, i.e. DIV = 3)

Truly!

I came up with a method that uses three bias curves, self modulated in series...

...but this script is much more elegant and leads to many interesting possibilities...

Cool stuff xirja!

I am working on improving "mode 2" (green ch. output) - the ramp should ideally be perpendicular to the spiral arm it represents. If you hook up a threshold you can easily see that the "angle" is not persistent...
