The Gizmo use a simple PositionToPoint node to redistribute each pixel in his UV space position. Works as the nuke default STMap but does exactly the opposite.

It can be used in many different ways, for example to know where to draw a roto in uv space, to be then distorted via STMap to mask a particular area of your CG render.

Or download from Nukepedia

Simply connect your Tracker node and your LensDistorsion node and hit Generate. This node automatically copy the tracker in a new one, and each keyframe of each track will come with the new undistort position. The core of this node is fully python based.

01-01-2013 – v1.1 – Now Works also with Tracker4 class Download
Or open lm_Distrack_v1.1 in new Tab, copy all and paste in your nodegraph

28-10-2013 – v1.0 – Start Release

Knowing issue:
– If the track goes over the format boundaries it will return wrong track, outside that area the lensdistorsion math doesn’t work because tends to infinity, but next version will comes with an overscan choise to give you a bit of more flexibility.

Next version will come with:
– Undistort/distort pulldown choise
– UVmap input as lens distorsion information

Inside you can also find an example nuke script.
Note that this is a beta version, so comments are really welcome.
