:param La2: is the second point on the first line,
:param Lb1: is the first point on the second line,
:param Lb2: is the second point on the second line,

:return: - true if the intersection can be found, false - otherwise.
         - intersection: is the result intersection, of it can be found.
         example:

%Docstring
A Z dimension is added to ``point`` if one of the point in the list
``points`` is in 3D. Moreover, the Z value of ``point`` is updated with.

:param points: List of points in which a 3D point is searched.
:param point: The point to update with Z dimension and value.

:return: true if the point is updated, false otherwise
