!= Operator - This operation compares two points for inequality. Inequality is defined by
any property of one point not equaling the corresponding property of the other point.
Point3 pt1 = new Point3(10, 20, 30);
Point3 pt2 = new Point3(20, 30, 40);
Point3 pt3 = new Point3(10, 20, 30);
bool result = (pt1 != pt2);
//result is true
result = (pt1 != pt3);
//result is false
== Operator - This operation compares two point instances for equality. Equality is defined
by all properties of one point being equal to the corresponding properties of the other
point. X equals X, Y equals Y, and Z equals Z.
Point3 pt1 = new Point3(10, 20, 30);
Point3 pt2 = new Point3(20, 30, 40);
Point3 pt3 = new Point3(10, 20, 30);
bool result = (pt1 == pt2);
//result is false
result = (pt1 == pt3);
//result is true
double Operator – This operation will convert a Point object to an implicit array of
doubles. The returned array will contain the properties of the Point in the order X, Y,
and Z. The array size will be adjusted up or down to match the size of the Point object.
The definition for the operator is:
public static implicit [ ] operator double(Point3 arg);
Given a Point3 defined to contain an X of 10, Y of 20, and Z of 30, the double
representation will be an array of {10, 20, 30}.
Point3 pt1 = new Point3(10, 20, 30);
double[ ] dbArray = pt1;
//dbArray = { 10.0, 20.0, 30.0 }
Point Operator (Point2 or Point3) – The Point operator will explicitly cast an
array of doubles to a Point object. The values in the array will be defined as the X, Y,
and Z properties respectively. The array size must match the dimension of the Point
