Yeah basically, it does just that. These are just new waters for me and
if there's a way to do this without ICE, great, I'm just not familiar
with what my options are. At least I have a working ICE solution.

Hey Tim --
Doesn't the position of the null == the "position in space where the
ray from the camera intersects that surface" when you've snapped the
null to the geo in the viewport?
This might be simpler although less cool than the ICE approach. You'd
also easily be able to keyframe the null's position.

But the distance I want is the distance between the camera and the
closest point on an arbitrary geometric surface behind the target.
Now maybe the easiest thing to do would be to snap the target to
said surface and get that distance. But there again, I need to
identify the position in space where the ray from the camera
intersects that surface.

Hey Tim,
I would use a expression.
open the exression editor-->Function-->Distance-->distance to camera
the result would be something like
ctr_dist_cam( null. )
null. would be the object name you're using to mesure the distance.
hope that helps

I'm trying to set up a camera rig that will let me use an item
of some kind (null, curve...) to act as a kind of focal point
that can be moved around the frame. Basically I want to have a
control parented to the camera which I can move around the
frame, and which can be used to create a vector between the
camera and whatever surface is "behind" that focal control. I'd
then get the distance between the camera and that point on the
surface and pass that to my lens shader.
I'm really a noob when it comes to ICE in general, so I'm
wondering how best to do this. I suck with vectors...
