Awesome Chris,
usefull script driving algorithm, had'nt
yet though about the blend tween falloff points. Fortunately all
points need use the same falloff formula (smooth1), only their gray
shades representing transparency will differ. But a bad blend would
still have edge difficulties as you precautioned ala: Hitchhikers
"needle in haystack", Lol.
Able to initialize and edit Control and Feather point knobs, just
can't edit the falloff they control,...yet?
Also, there probably is but i've not found other scripts, plugins or
programs with Feather, Point Falloff Color control?, i'm open to even
names of any software you suggest with similar falloff capabilities
just so i don't miss trying one.
thx again,
Jeff

i'm not very savvy with roto but i imagine one would have to solve
some fundamental problems which are quite tricky.. for instance:
what would happen to the falloff behavior *between* control points?
assuming the falloff gets generated by mathematical formulas, lets
say point A has a linear falloff and point B has a power function.
now we look at a non-control point point C somewhere between A and B
(cue hitchhikers guide reference ;), what formula would you apply
there? to get a smooth transition from A to B we'd need to
dynamically change formula A to formula B. i guess you could try a
dissolve between the two but i imagine the math gets rather complex
and in worst case that would result in some kind of double edge.
just some thoughts

Thanks much for your reply.
- dragging out the feather control points would only change the
DISTANCE of the Feather Falloff at each point, but i need to change
the COLOR or Grey Shade at EACH control\feather point, which is
what the Feather Falloff Value lightens or darkens but only for the
Entire SHAPE or ROTO.
Any ideas\suggestions appreciated,
Jeff
