Like this:
***
import nuke.rotopaint as rp
SplineWarpNode = nuke.createNode('SplineWarp3')
curvesKnob = SplineWarpNode['curves']
shape = rp.Shape(curvesKnob)
***
shape gives: TypeError: argument 1 must be (unspecified), not
_splinewarp.SplineKnob
I know that rotopaint node uses _rotopaint.RotoKnob and when i try
shape = rp.Shape(curvesKnob)on a roto node it works.
So which method should i use to create shapes inside a SplineKnob?
Thanks in advance,
Magno
Hi Magno,
could you send some of the Python you've been trying?
Thanks,
Wouter

Another question on the same subject. Is it possible to create Shapes
inside spline warp nodes via Python scripting? Because i'm trying to
apply some of the rotopaint python exemples on the node and its not
working.
What I'm missing?

Hi all,
The way source and destination curves work will change for the next
major version of Nuke, but in 6.3 the source and destination are
essentially the same curve, similar to Roto and it's feather curve.
(Hence the awkward naming..)

Yeah the naming was not helping! Thanks Ivan, that was exactly what
i needed.
Magno.
Each control point has both the source and destination
attributes. The confusing part is that the naming of those
attributes makes more sense for a standard roto shape.
So, your source curve is:
controlPoint.center
and the dest curve is:
controlPoint.featherCenter
Also, if you're getting the position data out of each attribute,
keep in mind that the dest points are stored as an offset
relative to the src point, instead of an absolute position.
Have a look at the output of this:
node = nuke.selectedNode()
curves = node['curves']
sourcecurve = curves.toElement('Bezier1')
for p in sourcecurve:
print p.center.getPosition(nuke.frame()),
p.featherCenter.getPosition(nuke.frame())
Hope that helps.
Cheers,
Ivan

Hello!
I trying to figure out how to access the *control points *of
the***destination* curves of the SplineWarp node via python.
The points of the source curves are easy:
node = nuke.selectedNode()
curves = node['curves']
sourcecurve = curves.toElement('Ellipse1')
With sourcecurve[0], sourcecurve[1], etc i can access each
control point.
Any help?
