Geometry
IsNull - This method determines if the input Vector has a Null definition and returns
true if it does. A null vector is a vector that has one or more properties whose value is
NaN so it cannot represent a geometric entity.
Vector3 vt1 = new Vector3(10, 20, 30);
bool result = Vector3.IsNull(vt1);
//result is false
vt3 = Vector3.Null;
result = Vector3.IsNull(vt3);
//result is true
ToString - This method gets a string representation of this instance.
Vector3 vt1 = new Vector3(10, 20, 30);
string str = vt1.ToString();
// str = (10, 20, 30)
Direction2 and Direction3 Classes
The Slb.Ocean.Geometry namespace defines two sealed direction classes called
Direction2 and Direction3 in the Euclidean 2D and 3D space respectively. Direction
is lengthless vector, i.e. a vector whose length is insignificant.
