Hi;(adsbygoogle = window.adsbygoogle || []).push({});

First i you read my problem and feel that it does not belong to this forum please inform me which one is the right one.

I have 2 lines L1,L2 in 3-dimensions

L1 has (x1,y1,z1) (x2,y2,z2)

L2 has (x3,y3,z3) (x4,y4,z4)

How can I know that these two lines are intersected?

Thanks

toto
