Hi, i need enlightenment on this question of mine. Suppose i have two lines, L and M. L and M intersect at point X. Then is X a cross product of L and M? I read this from a pdf on Multiple View Geometry. Here the link http://www.syseng.anu.edu.au/~hartley/Papers/CVPR99-tutorial/tut_4up.pdf the eqn is on pg 8 top right corner slide. Thanks in advance!
