示例1:
/**
* Computes 2D intersection point of two lines, but also finds z component (projected by time from line 1)
* @param s0 starting point of line 1
* @param v0 direction vector for line 1
* @param s1 starting point of line 2
* @param v1 direction vector of line 2
* @return Pair (2-dimensional point of intersection with 3D projection, relative time of intersection, relative to the so3)
* If the lines are parallel, this returns the pair (0,NaN).
