This is probably what you are after.

There is a built in function that does pretty much that, when you
click "match position" and select the animated one. I'm pretty sure I
saw the code for that in the reference, you might want to look at it.

Hi !
I found a workaround a while ago to update the viewer to the next
frame. You want to use a *curveTool *node.
In your python script before the loop create your node then
execute it for frame "i" in your loop.
I don't have access to my scripts but you can refere to the Nuke
python api.
Don't forget to delete your CurveTool node at the end of your script.
Cheers,
Justin

Hi there,
I'm kinda stuck with a script, and though I think its probably
an easy fix, I haven't found the solution yet.
A very simplified version of what I want:
- grab the 3d position of a selected vertex,
- print this value
- move to the next frame and repeat.
The script I came up with :
import nukescripts.snap3d
for i in range (0,100):
nuke.frame(i)
vertex = nukescripts.snap3d.getSelection()
for v in vertex:
vertexXpos = v.position[0]
print vertexXpos
The problem is that, when executed in a loop, the
vertexposition is identical for every frame (it always uses
the values of the first frame). If I remove the forloop and
just execute the script manually on every frame it works as it
should.
My guess would be that I have to force the 3dviewer to refresh
on every frame so it updates the vertexpostion. Am I right,
and if yes how can I achieve this.
Thanks!
