Thanks for the extra insight John. I think I'll need to re-read a few more times and do some background research get my head around the issue.
I am starting to wonder if perhaps RayIntersector shouldn't just have a Vec3d start and direction rather than offer the possibility of using Vec4d for positions, this way we avoid the issues with putting both points at infinity, users will also be more used to thinking of ray as start and direciton.
