This object represents a 3D vector (X, Y and Z values). It is used by many other objects and can also be used with other geometry objects such as Point3D to perform calculations.

==Constructor==

===Vector3D()===
This construct an uninitialized vector with invalid x, y and z values which can be tested for using the .IsInvalid property.

===Vector3D(double x, double y, double z)===
A vector point with the specified values x(double) the value for the x coordinate of the vector y(double) the value for the y coordinate of the vector z(double) the value for the z coordinate of the vector

===Vector3D(Vector3D vec)===
A new vector with the same X, Y and Z values as the passed vector vec (Vector3D)

::''Note: an existing vector to copy values from''

==Properties==

===.IsInvalid===

'''Returns:''' (bool) true if the vector is invalid Note: not initialised or:SetInvalid called
===.Length===

'''Returns:''' (the length of the vector
===.LengthSq===

'''Returns:''' (the length squared of the vector. If comparing distance between points etc. using LengthSq instead of Length will be

faster as it avoids the square root operation required to find the exact length.
===.X or .x===
'''Interaction:''' Read and Write

'''Returns:'''(double) x coordinate for point

===.Y or .y===
'''Interaction:''' Read and Write

'''Returns:'''(double) y coordinate for point

===.Z or .z===
'''Interaction:''' Read and Write

'''Returns:'''(double) z coordinate for point

==Methods==

===:Cross(Vector3D vec)===
'''Returns:''' (the cross product (a Vector3D) of this vector and passed vector

===:Dot(Vector3D vec)===
'''Returns:''' (the dot product (a double value) of this vector and passed vector

===:Dot(Point3D vec)===
'''Returns:''' (the dot product (a double value) of this vector and passed point. The X,Y,Z values of the point are treated exactly the same as for the Vector3D version of this method.

===:Normalize()===
Normalize this vector to make it a unit vector

===:Set(double x, double y, double z)===
Set the x, y and z values for the vector x(double) new x value for vector y(double) new y value for vector z(double) new z value for vector

===:SetInvalid()===
Set the vector to invalid state X, Y and Z will be lost

==Operations==

===Double * Vector3D===
'''Returns:''' a new vector multiplied by double value

===Vector3D + Vector3D===
Adding a vector to a vector will returns a new vector.

===Vector3D - Vector3D===
Subtracting a vector from a point will returns a new vector.

=== - Vector3D===
Negates x,y and z values of vector (reverses vector direction)
