Geometry
+ Operator - This operation returns the same line.
Line3 l3 = +l1;
//l3 is {5x+5y+5z+-150=0}
== Operator - This operation compares two instances for equality.
bool result = (l1 == l3);
//result is true
Line classes define the following public methods (Line3 for examples):
Equals - This method compares this instance with another object for equality. Returns
true if this instance is equal to the other object.
Point3 p1 = new Point3(10,10,10);
Direction3 d1 = new Direction3(5,5,5);
Line3 l1 = new Line3(p1, d1);
//l1 is {5x+5y+5z+-150=0}
Line3 l2 = +l1;
//l2 is {5x+5y+5z+-150=0}
bool result = l1.Equals(l2);
//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.
Line3 l1 = Line3.Null;
//create a null Line
bool result = Line3.IsNull(l1);
//result is true
ToString - This method gets the string representation of this line. This returns a
string formatted as an equation: ax + by + cz + d = 0 where a, b, c, and d are constants.
