How to get the same annotation position points in the next frame?

IT-Highmore · August 7, 2024, 4:00am

As title show, I want to get the same annotation position points in the next frame.
For example, I draw a rectangle in one volume viewport, the coordinates of four points will be obtained.

How to calculate the coordinates of the four points at the same position in the next frame based on these four points?
I’m curious if this is possible?
