Hello all,
Given two 3D lines described by the general equation
[tex]\vec{L(t)}=\vec{p}+\vec{d}t[/tex]
I found a way to find their intersection point, but it uses the cross product in the derivation. I am assuming a 4D line is a valid thing? And can be described the same way? (except with 4 element vectors). If so, how can I find their intersection, as I read the cross product is undefined in 4 dimensions?
Cheers,
Adrian
