The plane passes by the origin and the

surface of it is perpendicular to the unit vector (or *normal*). The

-side towards the vector points to is the positive half-space, while the

|
+side the vector points to is the positive half-space, while the

|
other side is the negative half-space. In 3D this is exactly the same,

|

except that the plane is an infinite surface (imagine an infinite, flat
|
|
|
sheet of paper that you can orient and is pinned to the origin) instead
