Geometry
== Operator - This operation compares two instances for equality.
Segment3 seg = new Segment3(new Point3 (1, 2, 3),
new Point3 (5, 10, 15));
//seg is {(1,2,3),(5,10,15)}
Segment3 seg1 = +seg;
bool result = (seg1 == seg)
//result is true
Segment3 class defines the following public methods:
Equals - This method compares this instance with another object for equality. Returns
true if this instance is equal to the other object.
Segment3 seg = new Segment3(new Point3 (1, 2, 3),
new Point3 (5, 10, 15));
//seg is {(1,2,3),(5,10,15)}
Segment3 seg1 = +seg;
bool result = seg.Equals(seg1);
//result is true
GetHashCode - This method gets the hash code for this instance.
IsNull - This method determines if the given instance has a Null definition.
//create a null Segment
Segment3 seg = Segment3.Null;
bool result = Segment3.IsNull(seg);
//result is true
ToString - This method gets the string representation of this segment. This returns a
string formatted to indicate that it represents a segment. The string appears as "{point} o-
--o {point}" where {point} is formatted using the Point2 or Point3 ToString
method. The “o---o” indicates the data is a segment.
LatticeInfo Class
The Slb.Ocean.Geometry namespace defines LatticeInfo class to define a lattice.
A lattice describes the real world location of a 2-dimensional array of sample values. This is
