Given two segments, for example
S1=(2,1)-(2,3)
S2=(7,8)-(2,3)
the intersection test would be false.
However, if I use the cross-products test the result is true. I understand the two segments have a point in common but is there a way to exclude those endpoints from the test?
Clearly they intersect at (2,3) . Run a dry run by co-ordinate geometry. :)
