Perhaps you could sample the input depth at the position of the
Reconcile3D node's 'output' knob? You could do this by putting an
expression like this in ZDefocus's 'focus plane' knob:
[sample this depth.Z Reconcile3D1.output.x Reconcile3D1.output.y]
Then you wouldn't need the curve tool.
Cheers,

Hello All,
I am trying to setup a script that would let you drive the ZDefocus
knob "focal length (C)" with an axis node. The issue that I am running
into is that this value only updates when the users moves the "focal
point" widget. But the "focal point" can not be driven with a curve.
To get around this I am using a camera and axis plugged into a
Reconcile3D node. Then that XY is plugged into a CurveTool with its
area set to 1 pixel by 1 pixel which I then generate the average
intensities of that tracked pixel to get me a curve which I can plug
into "focal length (C)". Is there anyway to cut the CurveTool out of
this, so that I don't have to generate keys every time I move the
axis? Maybe using callbacks? Thank you.
