1.3. Planes

Planes in 3D Space

A plane is a flat, two-dimensional surface that extends infinitely in two directions defining a local coordinate system:

Planes

The normal vector (n) is a perpendicular vector to this plane at a given point. It is the result of the Cross Product of the two vectors (x and y) contained in that plane.

Planes

In combination with XY, YZ and XZ we get:
