There's a great paper from Ryan Schmidt called "Interactive decal compositing with discrete exponential maps" which tackles this exact problem as well. A more modern variant can be found in the "Vector Heat Method" by…
Not to be pedantic, but one of the author's own examples involves pi inverse, so I think discussing FP numbers is valid.
