Principal unit normal vector
How do you calculate the normal vector?
A vector lying in the plane is found by subtracting the first point's coordinates from the second point. A second vector lying in the plane is found by subtracting the first point's coordinates from the third point. The normal vector is found by calculating the cross product of two vectors lying in the plane.
How to calculate normal vector?
Summary Given a surface parameterized by a function , to find an expression for the unit normal vector to this surface, take the following steps: Get a (non necessarily unit) normal vector by taking the cross product of both partial derivatives of : Turn this vector-expression into a unit vector by dividing it by its own magnitude:
