The Direction3 class is defined as:
public sealed class Direction3
{
public static readonly Direction3 Null;
public static readonly Direction3 Zero;
public Direction3(double x, double y, double z);
public Direction3(Direction3 input);
public Direction3(Vector3 input);
public static Direction3 operator - (Direction3 arg);
public static bool operator != (Direction3 lhs, Direction3 rhs);
public static Direction3 operator + (Direction3 arg);
public static bool operator == (Direction3 lhs, Direction3 rhs);
public static explicit operator Vector3 (Direction3 arg);
public static implicit operator Direction3 (Vector3 arg);
public Vector3 NormalizedVector { get; }
public double X { get; }
public double Y { get; }
public double Z { get; }
public override bool Equals (object obj);
public override int GetHashCode ();
public override string ToString ();
public static bool IsNull (Direction3 obj);
public static Direction3 Negate (Direction3 arg);
public static Direction3 Plus (Direction3 arg);
}
The Direction2 and Direction3 classes provide the same constructors, properties,
and methods. They vary only in the dimensions available. The Direction2 class is two
dimensional and has only X and Y components. The Direction3 class is three
dimensional and therefore has a Z component. The following sections detail the
constructors, properties, and methods available.
