Hi,
I'm trying to implement circular scrolling with the trackpad in pd and am approaching it by dividing a circle into segments and trying to detect when the mouses moves from one segment to the other. At the moment I can only detect 4 segments (basically just the zero crossings) which is not really accurate enough.
How would I go about detecting the boundaries of the 12 segments in the attached patch (circscroll.pd)?
Eventually I want to detect speed and direction too - but perhaps there is a better approach?
any advice welcome.
thanks,
james
