info from 3DE, using the 3DE Export Nuke CornerPin2D Node
Stereo Stabilizing python script
On 5/29/12 6:48
I have a
question about the "Export Nuke CornerPin2D Node
Stereo Stabilizing v1.3" function in 3DE:
Is the resulting cornerpin node meant to be applied to the
the undistorted plates?
Well, the current version of that script works on *distorted*
2D/3D point positions. That
- track the raw footage in 3DE
- export the corner pin
- apply the cornerpin to the raw footage
- undistort the resulting image
...how are the results? Are there any problems?!
We could potentially add an option to that script which would
allow it to operate on *undistorted*
2D/3D point positions
instead (which means that the order of nodes within Nuke
must/could be reversed)!

Does it also require undistort nodes or is it stand alone?
Rolf from 3DE: It does not
undistort anything. It tries to align one plate to the other
using a (4 point) cornerpin node.
Is the full homography best?
Rolf from 3DE: Well, it will align plate A to plate B in
the most "aggressive" way possible. Most likely something
you don't want, since you will lose almost all i/o and the
convergence point will be highly different...
You probably want to use one of the "y" modes, which will
ensure that the original i/o & convergence stays
Does it work with the undistort plates
out of a Maya scene/render or is
the script purely for reconcile of stereo eyes. Is it going
to try to
Rolf from 3DE: Again, it does not undistort anything. It
uses the tracking data present in 3DE (either 2D tracking or
backprojected 3D points) to compute a 2D alignment (pure
Let me know how it goes!
