Hi, there are many ways of animating vines or strokes -seen a couple of questions these days- and here’s yet another one
Since rotobezier is around I’ve been thinking in animating the radius to fade a curve ‘visibility’, this script does that by keyframing each point, it works with bezier and nurbs -beziers seems to work better- and you can even feed it with a mesh or a text and it will do the conversion.
You should setup start frame and length, plus a fade time if you want the curve to disappear.
It is advisable to subdivide the curve if you want to give extra detail to the animation.
Options like bevel depth and resolution can be adjusted later.
Here’s previous video only that in vimeo… just threw a torus knot on scene -what a cool addon- and then ran this little script… Try the same with different settings. Remeber you can even run it on a mesh or a text. Subdivision are important here.
@benu that was fun -maybe not so for the monkey-
here is an updated version of the script, I tried to make it even simpler to use, but it will work better on a 37260 build at least… please give it a try and tell me what you think!
just select the mesh and click on button, it will do the conversion for you… maybe go edit mode and press the V key > automatic to change handles type…
but try it on you own curves, the point density there is a key factor to get nice results
you can’t have fills and radius -or a bevel object- in the same curve in blender… use two objects
and try curve simplify addon to reduce point count, too dense curves are bad
I am trying to use the grow radius script. No matter the object I choose(curve, polygon, subdivided or not) when I hit Keyframe Curve I get the following error:
Traceback (most recent call last):

I use Blender 2.59.4, r40851M, built by bat3a from Graphicall. I am on a Windows 7 64 bit machine. Pyhon version is 3.2.2.
I saw the changes to curves some days ago but didn’t think of updating scripts, thanks for reminding…! this should be fixed now. And remember to subdivide the curve if needed.
Thanks Meta-Androcto, checking other curve scripts now… done, I think I’ve fixed and uploaded them all
Meta-Androcto, thank you for reply. I tried your trick but it only works on a limited tipe of curves. For example it does not work on polygons.
Liero, I just downloaded the updated versions of the scripts and works like a charm. Thank you very much for sharing with us all that works and efforts to do marvelous things.
