Could you provide some more context for your thinking here? It's not
clear to me what kind of computational problem you're talking about.
Thus I can't comment on whether partitioning the problem between Scheme
and C is easy or onerous.

In my opinion, computational geometry is both high and low level stuff,
often in the same context. One shouldn't be burdened with
re-implementing the code in C.
I think it depends on your desired outcome. I'm guessing that if
you're concerned with fp performance and optimization in particular,
you must want to do large repetitive sequences of floating point
calculations. The logical way to handle this in Chicken is to put the
sequences into vector or matrix form and use a suitable C or C++ math
package to perform the transformations you want. But I know nothing
about modern game production so I don't know whether this would answer
your concerns. It would probably be very easy to do, though.
