	Vector3d(Vector3d)	Initializes a new instance of a vector, copying the three components from a vector.
	Vector3d(Vector3f)	Initializes a new instance of a vector, copying the three components from a single-precision vector.
	Vector3d(Double, Double, Double)	Initializes a new instance of a vector, using its three components.

Properties

	Name	Description
	IsUnitVector	Gets a value indicating whether or not this is a unit vector. A unit vector has length 1.
	IsValid	Gets a value indicating whether this vector is valid. A valid vector must be formed of valid component values for x, y and z.
	IsZero	Gets a value indicating whether the X, Y, and Z values are all equal to 0.0.
	Item	Gets or sets a vector component at the given index.
	Length	Computes the length (or magnitude, or size) of this vector. This is an application of Pythagoras' theorem. If this vector is invalid, its length is considered 0.
	MaximumCoordinate	Gets the largest (both positive and negative) component value in this vector, as an absolute value.
	MinimumCoordinate	Gets the smallest (both positive and negative) component value in this vector.
	SquareLength	Computes the squared length (or magnitude, or size) of this vector. This is an application of Pythagoras' theorem. While the Length property checks for input validity, this property does not. You should check validity in advance, if this vector can be invalid.
	Unset	Gets the value of the vector with each component set to RhinoMath.UnsetValue.
	X	Gets or sets the X (first) component of the vector.
	XAxis	Gets the value of the vector with components 1,0,0.
	Y	Gets or sets the Y (second) component of the vector.
	YAxis	Gets the value of the vector with components 0,1,0.
	Z	Gets or sets the Z (third) component of the vector.
	ZAxis	Gets the value of the vector with components 0,0,1.
	Zero	Gets the value of the vector with components 0,0,0.

Methods

	Name	Description
	Add	Sums up two vectors. (Provided for languages that do not support operator overloading. You can use the + operator otherwise)
	AreOrthogonal	Test whether three vectors describe an orthogonal axis system. All vectors must be mutually perpendicular this to be the case.
	AreOrthonormal	Test whether three vectors describe an orthogonal, unit axis system. All vectors must be mutually perpendicular and have unit length for this to be the case.
	AreRighthanded	Test whether three vectors describe a right-handed, orthogonal, unit axis system. The vectors must be orthonormal and follow the right-hand ordering; index-finger=x, middle-finger=y, thumb=z.
	CompareTo	Compares this Vector3d with another Vector3d. Component evaluation priority is first X, then Y, then Z.
	CrossProduct	Computes the cross product (or vector product, or exterior product) of two vectors. This operation is not commutative.
	Divide	Divides a Vector3d by a number, having the effect of shrinking it. (Provided for languages that do not support operator overloading. You can use the / operator otherwise)
	EpsilonEquals	Check that all values in other are within epsilon of the values in this
	Equals(Object)	Determines whether the specified System.Object is a Vector3d and has the same values as the present vector. (Overrides ValueTypeEquals(Object).)
	Equals(Vector3d)	Determines whether the specified vector has the same value as the present vector.
	GetHashCode	Computes the hash code for the current vector. (Overrides ValueTypeGetHashCode.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsParallelTo(Vector3d)	Determines whether this vector is parallel to another vector, within one degree (within Pi / 180).
	IsParallelTo(Vector3d, Double)	Determines whether this vector is parallel to another vector, within a provided tolerance.
	IsPerpendicularTo(Vector3d)	Test to see whether this vector is perpendicular to within one degree of another one.
	IsPerpendicularTo(Vector3d, Double)	Determines whether this vector is perpendicular to another vector, within a provided angle tolerance.
	IsTiny	Uses RhinoMath.ZeroTolerance for IsTiny calculation.
	IsTiny(Double)	Determines whether a vector is very short.
	Multiply(Double, Vector3d)	Multiplies a vector by a number, having the effect of scaling it. (Provided for languages that do not support operator overloading. You can use the * operator otherwise)
	Multiply(Vector3d, Vector3d)	Multiplies two vectors together, returning the dot product (or inner product). This differs from the cross product. (Provided for languages that do not support operator overloading. You can use the * operator otherwise)
	Multiply(Vector3d, Double)	Multiplies a vector by a number, having the effect of scaling it. (Provided for languages that do not support operator overloading. You can use the * operator otherwise)
	Negate	Computes the reversed vector. (Provided for languages that do not support operator overloading. You can use the - unary operator otherwise)
	PerpendicularTo(Vector3d)	Sets this vector to be perpendicular to another vector. Result is not unitized.
	PerpendicularTo(Point3d, Point3d, Point3d)	Set this vector to be perpendicular to a plane defined by 3 points.
	Reverse	Reverses this vector in place (reverses the direction). If this vector is Invalid, no changes will occur and false will be returned.
	Rotate	Rotates this vector around a given axis.
	Subtract	Subtracts the second vector from the first one. (Provided for languages that do not support operator overloading. You can use the - operator otherwise)
	ToString	Returns the string representation of the current vector, in the form X,Y,Z. (Overrides ValueTypeToString.)
	ToString(String, IFormatProvider)	Formats the value of the current instance using the specified format.
	Transform	Transforms the vector in place. The transformation matrix acts on the left of the vector; i.e., result = transformation*vector
	Unitize	Unitizes the vector in place. A unit vector has length 1 unit. An invalid or zero length vector cannot be unitized.
	VectorAngle(Vector3d, Vector3d)	Compute the angle between two vectors. This operation is commutative.
	VectorAngle(Vector3d, Vector3d, Plane)	Computes the angle on a plane between two vectors.
	VectorAngle(Vector3d, Vector3d, Vector3d)	Computes the angle of v1, v2 with a normal vector.
