I might add that PDL might be the most flexible solution. It's piddles can handle matrix manipulation fast and with some cool tricks too, that you might never expect. It seems to me you are looking to solve the problem of how to find the intersection of a vector and a planar surface. If I were you, I would ask this on the very friendly and helpful PDL maillist. The geniuses there ( not including me :-) ) have learned the tricks of piddle fu, and may just know the perfect piddle you need to be the fastest and most efficient. Which is the name of the game of course. :-)

PS: PDL was designed in Fortran, which I assume, from your name, interests you f77coder
