In fact that seems nothing more than the previously proposed custom vector
function and the possibility to use the intersection information (ray,
normal) in functions. The latter involves the problem that the function
will only be defined on an object surface - just like the slope pattern
which results in various problems.

Custom vector functions will probably not be that easy (at least according
to what Thorsten said, i did not look into that matter more deeply) but
surely not impossible.
