Hi Magno,
thanks for your reply and sorry for not replying earlier.
I did take a look at your script, but couldn't get it to work. I copied to
corner pin matrix values to a new corner pin, but they don't seem to match.
Any idea? Then again, I'm no python expert.
The script Pete O'Connel posted to this list eralier works, but I don't get
any animated values out of it. Anyone know how to modyfi it? Basically I
want to run the script on a corner-pin node, and create a Gridwarp with
that transform matrix.
Here's Pete's script again. Hope you don't mind me reposting it.
import nukedef getTheCornerpinAsMatrix():
projectionMatrixTo = nuke.math.Matrix4() projectionMatrixFrom =
nuke.math.Matrix4() #dir(projectionMatrix) theCornerpinNode =
nuke.selectedNode()
imageWidth = float(theCornerpinNode.width()) imageHeight =
float(theCornerpinNode.height()) to1x =
theCornerpinNode['to1'].value()[0] to1y =
theCornerpinNode['to1'].value()[1] to2x =
theCornerpinNode['to2'].value()[0] to2y =
theCornerpinNode['to2'].value()[1] to3x =
theCornerpinNode['to3'].value()[0] to3y =
theCornerpinNode['to3'].value()[1] to4x =
theCornerpinNode['to4'].value()[0] to4y =
theCornerpinNode['to4'].value()[1] from1x =
theCornerpinNode['from1'].value()[0] from1y =
theCornerpinNode['from1'].value()[1] from2x =
theCornerpinNode['from2'].value()[0] from2y =
theCornerpinNode['from2'].value()[1] from3x =
theCornerpinNode['from3'].value()[0] from3y =
theCornerpinNode['from3'].value()[1] from4x =
theCornerpinNode['from4'].value()[0] from4y =
theCornerpinNode['from4'].value()[1]
projectionMatrixTo.mapUnitSquareToQuad(to1x,to1y,to2x,to2y,to3x,to3y,to4x,to4y)
projectionMatrixFrom.mapUnitSquareToQuad(from1x,from1y,from2x,from2y,from3x,from3y,from4x,from4y)
theCornerpinAsMatrix =
projectionMatrixTo*projectionMatrixFrom.inverse()
theCornerpinAsMatrix.transpose() return theCornerpinAsMatrix
Best regards,
Simon
