Convert multiple 3D points to 2D tracker points really fast!
Requirements:
13.1, 13.0, 11.3 or later
Linux, Mac, Windows

This small node uses a script to take multiple axis nodes and a camera and converts them to 2D tracks in a tracker node.

It skips the previous technique of having to connect an axis point to a reconcile3D, track and copy the animation data over to a tracker, for every single axis.

Now connect all axis points up to this one node and track them all in one click, then simply export the tracker node with the tracks.

Very useful for getting tracks and cornerpins in complex scenes with camera moves.

Please let me know if you find any issues or bugs and enjoy!

reconcile3DPro Example

Know Issues

  • Having an axis connected to the camera breaks it.
  • When creating axis points having anything else selected causes issues.

1.1 Changes - 25 March 2021

You can now select points in the 3D viewer and create connected axis points with the 3D position set to the selected point. Saving time manually creating axis points, snapping them to vertex points and linking them up.

This is handy and save a lot of time, thanks!
I noticed that the tool throws an error message, when the camera has an axis input. Camera evaluation in gizmos is an issue, but maybe you can use DummyCam (http://www.nukepedia.com/gizmos/3d/dummycam) to make this a little bit more robust :)

Thanks for trying it out Nikoloai and bringing this error to my attention. It's because the camera input will be looking for the top node, which will usually be the camera, unless an axis is connected. So it thinks the axis is the plugged in camera and causes the error. I will take a look at a fix.

I also just updated the tool with a pretty cool new feature! :D

Would it be possible to have an option to create animated axis? Currently it only snaps to a static 3D point and would be useful to have that functionality built in to this. Great tool though. Cheers

Hi Josh, thanks for the feedback, I will take a look into implementing this feature.

For now I would suggest using AnimatedSnap3D.

http://www.nukepedia.com/python/3d/animatedsnap3d

You can then use that to create your animated axis points and then use Reconcile3DPro to convert those to 2D tracker points.

Hey Luke -- this is pretty sweet! I was thinking of making something similar.

Is there a Resolution size or Pixel Aspect ratio limitation to the algorithm ? I have some footage that is pixel aspect ratio 2.0 and the reconcile is coming out off.

Hi M Frank!

That's really weird but can't say I have ever tested it with pixel aspect ratio 2.0.

I know that if your window "downres" ISN'T on 1:1 it will come out wrong.

If you find a fix please let me know and comment/pull on Github linked above.

Thanks for writing this script!

Updated for Nuke 13 here, I also added support for the Camera3 node because it seems to work fine with it and will throw errors otherwise: https://gist.github.com/Shrinks99/796340ab0efc80eb8d791f8a69e73cbd

Thanks Henry, I have updated the script with your changes.

If you find anymore bugs and want to fix them please comment/pull request on the linked Github repo above!
