Re: [Nuke-users] Gathering roto values to drive a tracker
You can get the position of the point through the curve editor - to get the offset subtract the reference value. If you do this with 2 points then with clever maths that someone else can point you to you'd get the rotation. How you get rotation values from one point I dont know??

I want to gather the rotation and translation of 2 points of a roto shape and use that information to drive a tracker. Any help will be appreciated Cheers, César Rodríguez B.

Yes, via python.I've created a script recently that does that. :)http://www.nukepedia.com/gizmos/bakerotoshapestotrackers/ Hi there,Is there a way to link the translate and rotation values of a single point of a roto shape to a tracker on nuke?

Re: [Nuke-users] Gathering roto values to drive a tracker
magno's scripts rock. if you've not seen his warper scripts, definitely worth checking out. unless I'm missing what you're after - you can right click a point in the viewer and copy point link and paste it onto the x/y curve of a tracker. you can set a 2nd point to derive rotation. you'll need to bake the curves before you can apply the transform, as the tracker doesn't like expressions (bug). right click the tracker curve, edit generate ok On Wed, Mar 7, 2012 at 11:10 AM, Magno Borgo mag...@pop.com.br wrote: Yes, via python.
