The slope pattern is only defined at the surface of the object it is
applied to.  Therefore you question does not seem to make sense to me.  

Using intersection information with an arbitrary object is of course an
interesting concept for a pattern or function.  See:

http://www-public.tu-bs.de:8080/~y0013390/povcyg/docu/docu_pattern01.html#OBJSLOPE

for an example.  It might be that in the future 'trace' will be made
available in functions too but not in Povray 3.5.
