The Ray3 class definition is:
public sealed class Ray3
{
public Ray3 (Ray3 input);
public Ray3 (Point3 point, Direction3 direction);
public Ray3 (Point3 point0, Point3 point1);
public Direction3 Direction { get; }
public bool IsDegenerate { get; }
public Point3 Origin { get; }
public static readonly Ray3 Null = new Ray3 (Point3.Null,
Direction3.Null);
public override bool Equals (object other);
public override int GetHashCode ();
public static bool IsNull (Ray3 obj);
public static Ray3 Negate (Ray3 arg);
public static Ray3 Plus (Ray3 arg);
public overrice string ToString ();
}
public static Line3 operator – (Ray3 arg);
public static bool operator != (Ray3 lhs, Ray3 rhs);
public static Line3 operator + (Ray3 arg);
public static bool operator == (Ray3 lhs, Ray3.rhs);
The Ray2 and Ray3 classes provide the same constructors, properties, and methods.
They vary only in the dimensions available. Ray2 objects are constructed from Point2
and Direction2 objects and Ray3 objects are constructed from Point3 and
Direction3 objects. The following sections detail the constructors, properties, and
methods available using Ray3 for the examples.
Each ray type has multiple constructors; the following examples use Ray3.
Here is construction from the point of origin and the direction of the instance:
Point3 origin = new Point3(0, 0, 0);
Direction3 direction = new Direction3(10.0, 10.0, 0.0);
Ray3 ray = new Ray3( origin, direction);
