Hi John,
Each control point has both the source and destination attributes. The
confusing part is that the naming of those attributes is "center" and
"featherCenter", because it shares the same attributes with the Roto Shapes.
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())
It's confusing indeed, but word from The Foundry was that this might change
in the next version.
Hope that helps.
Ivan
