How are lines represented in parametric / implicit form?
Parametric
With base point
, direction 
:
Implicit 2D
Find normal vector
to . Then, the line is given by all points 
for which
.
Implicit 3D
Find two vectors
orthogonal to . Then, the line is given by the intersection of the two planes given by 
, i.e. all points for which
