Well, that's going to depend on the details of how your animation runs, but you
could use a loop to simulate the relative positions of the union and the camera
and store the max/min in a file, and set a flag to not run the loop from then
onward.

Or output the result to the #debug stream and then halt the render.   Then
hard-code that number into the scene.
