Many of the people here would rather have the code than the
explanation...code they can use. If they could use the explanation then they
probably could have been worked it out themselves as it sounds you might be
able to.  They probably came to this list because they couldn't find the
code library to use...i.e. a function that returns a point when giving it
two lines.  Or, they want to write the code themselves in which case they
just want the formula/algorithm in a format that they can code with.

Checking a book is usually the first step...and yes, sometimes problems not
covered in the topics are presented as an exercise.  However, the solution
of the intersection of 2 lines in R3 does not present any new material and
thus is usually not included in a text book even as an exercise.  If you
find such a book that contains solutions to problems such as intersection of
2 lines in 3D then please let us know.
