!= Operator - This operation compares two rays for inequality.
Two instances are equal if their origins are the same and their directions are the same.
Note that comparing Ray3.Null to any other instance will return false. This is to
maintain consistency with the behavior of floating point NaN comparison.
bool result = (r1 != r);
//result is true
+ Operator - This operation returns the same ray.
Point3 originPt = new Point3(5, 5, 5);
Direction3 rayDi = new Direction3(3,3,3);
Ray3 r = new Ray3(originPt, rayDi);
Ray3 r1 = +r;
== Operator - This operation compares two instances for equality.
bool result = (r1 == r);
//result is true
Ray3 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.
Point3 originPt = new Point3(5, 5, 5);
Direction3 rayDi = new Direction3(3,3,3);
Ray3 r1 = new Ray3(originPt, rayDi);
Ray3 r2 = +r1;
bool result = r1.Equals(r2);
//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.
Ray3 r1 = Ray3.Null;
//create a null Ray
bool result = Ray3.IsNull(r1);
//result is true
