"Nettet14. aug. 2016 · The first thing to do is to find the intersection of the line with the plane of the triangle. The plane can be found by first computing the cross product of b − a and c − a to get a normal n to the plane, then finding k = n ⋅ a; the plane is the set of vectors w with n ⋅ w = k. Intersecting the line with the plane then means solving " - Line intersect triangle c#
