That is not a good argument the math could be in a separate chapter or
documentation.

This is very bad. Getting the math from a C (or C++) file is a nightmare.
Moreover, in a doc you can first give a simplification and the give
refinment. In the code you immediately have the full refined solution
where everything is mixed.
Moreover, the math involved are generally no so hard (linear algebra + a
bit of phisics and there are probably some artist that could surprise
you by understanding them :-)
