Hi Ron,
as it is only one transform you can calculate it with the matrix of the
transform node. I wrapped it in a NoOp here:
set cut_paste_input [stack 0]
version 6.3 v4
push $cut_paste_input
NoOp {
name TransformPosition
selected true
xpos 136
ypos -13
addUserKnob {20 User l TransformPosition}
addUserKnob {26 txt l "" +STARTLINE T "Connect a Transform node to the
input and get\nthe transformed position of 'pos' in 'transform'"}
addUserKnob {26 "" +STARTLINE}
addUserKnob {12 pos}
pos {200 300}
addUserKnob {12 transform}
transform {{"\[python
nuke.thisNode().input(0).knob('matrix').value().transform(nuke.math.Vector3(nuke.thisNode().knob('pos').value()\\\[0\\],\\
nuke.thisNode().knob('pos').value()\\\[1\\],\\ 0))\\\[0\\]]"} {"\[python
nuke.thisNode().input(0).knob('matrix').value().transform(nuke.math.Vector3(nuke.thisNode().knob('pos').value()\\\[0\\],\\
nuke.thisNode().knob('pos').value()\\\[1\\],\\ 0))\\\[1\\]]"}}
}
Connect the transform node to the input and set the pos knob to the
position you want to transform through the transform node.
Best regards,
Michael

Hi all,
is there a way to consolidate transformations?
I have a CornerPin, then a Transform, and I want the centre of the
CornerPin's four pins' location after it has been transformed. Easy to
get the centre of the corner pin, but the Transform has translate,
scale, and rotation in it, so it's not that easy.
Any idea?
