Geometry
!= Operator - This operation returns true if the two boxes have different corner points.
Box3 bt = new Box3(new Point3 (1, 20, 20), new Point3(10, 11, 30));
Box3 bt2 = new Box3(new Point3 (1, 20, 30), new Point3(10, 11, 40));
bool result = bt != bt2;
//result is true. boxes have different corners
In this example the two boxes have different corners so they are not equal. They have the
same X and Y dimension but have a different Z range.
== Operator - This operation returns true if the two boxes have the same corner points.
Box3 bt = new Box3(new Point3 (10, 10, 10), new Point3(20, 20, 20));
Box3 bt2 = new Box3(new Point3 (10, 20, 10), new Point3(20, 10, 20));
bool result = bt == bt2;
//result is true. boxes have the same corners
In this example the two boxes actually have the same corners. They are defined using
different corners, but the resulting corners of the boxes are the same.
Box3 has several public methods:
Equals – This method returns true if min and max are the same for two boxes. If two
boxes have the same min and max corners, then by definition they must be equal.
Box3 bt = new Box3(new Point3 (10, 10, 10), new Point3(20, 20, 20));
Box3 bt2 = new Box3(new Point3 (10, 20, 10), new Point3(20, 10, 20));
bool result = bt.Equals(bt2);
//result is true. boxes have the same corners
GetHashCode – This method gets the hash code for this instance.
IsInside – This method returns true if the point is inside the box.
Box3 bt = new Box3(new Point3 (1, 2, 3), new Point3(10, 11, 12));
bool result = bt.IsInside(new Point3 (5, 5, 5));
//result is true
result = bt.IsInside(new Point3 (20, 40, 50));
//result is false
