Represents an immutable ray in three dimensions, using position and direction.

Constructors

Ray3d

#Since v5.0
public Ray3d(Point3d position, Vector3d direction)
Initializes a new Ray3d instance.
Parameters:
position (Point3d)The position.
direction (Vector3d)The direction.

Properties

Direction

#Since v5.0
public Vector3d Direction { get; }
Gets the direction vector of this ray.

Position

#Since v5.0
public Point3d Position { get; }
Gets the starting position of this ray.

Methods

EpsilonEquals

#Since v5.4
[ConstOperation] public bool EpsilonEquals(Ray3d other, double epsilon)
Check that all values in other are within epsilon of the values in this
Parameters:
other (Ray3d)
epsilon (double)
Implements: EpsilonEquals

Equals

#
[ConstOperation] public override bool Equals(object obj)
Determines whether the specified System.Object is a Ray3d and has the same values as the present ray.
Parameters:
obj (object)The specified object.
Returns: true if obj is a Ray3d and has the same position and direction as this; otherwise false.
Overrides: ValueType.Equals

Equals

#Since v5.0
[ConstOperation] public bool Equals(Ray3d ray)
Determines whether the specified Ray3d has the same value as the present ray.
Parameters:
ray (Ray3d)The specified ray.
Returns: true if ray has the same position and direction as this; otherwise false.

GetHashCode

#
[ConstOperation] public override int GetHashCode()
Computes a hashing number that represents the current ray.
Returns: A signed integer that represents both position and direction, but is not unique.
Overrides: ValueType.GetHashCode

PointAt

#Since v5.0
[ConstOperation] public Point3d PointAt(double t)
Evaluates a point along the ray.
Parameters:
t (double)The t parameter.
Returns: A point at (Direction*t + Position).
Explicit

ISerializable.GetObjectData

#
[SecurityPermission(SecurityAction.LinkDemand, Flags = SecurityPermissionFlag.SerializationFormatter)] void ISerializable.GetObjectData(SerializationInfo info, StreamingContext context)
Parameters:
info (SerializationInfo)
context (StreamingContext)
