Need way more information and context to offer intelligent advice / solution.
Where is your input coming from?
Flat and round where?  On the edges?  On the face?
Can you use trace () ?
Maybe you need iterative interaction like I did with my analytical tangent
scene.
Details.

When I was making the Bezier stitched torus, I had my shape that was defined by
a set of parametric equations.  So I wrote macros to use where I was on the
parametric to find what patch I was on, and where in that patch I was.

Provide a workflow, diagrams, examples, etc - and there are surely solutions for
doing this.
If people are already doing it in other languages / software packages, we can
surely do it in POV-Ray.

I see you like to bite off huge projects like I do  :D
