Represents the four coordinates of a point in four-dimensional space. The W (fourth) dimension is often considered the weight of the point as seen in 3D space.

<SerializableAttribute>
Public Structure Point4d
	Implements ISerializable, IEquatable(Of Point4d)

The Point4d type exposes the following members.

	Name	Description
	Point4d(Point3d)	Initializes a new instance of the Point4d class from the coordinates of a point.
	Point4d(Double, Double, Double, Double)	Initializes a new instance of the Point4d class based on coordinates.

	Name	Description
	Unset	Gets the value of a point with all coordinates set as RhinoMath.UnsetValue.
	W	Gets or sets the W (fourth) coordinate -or weight- of this point.
	X	Gets or sets the X (first) coordinate of this point.
	Y	Gets or sets the Y (second) coordinate of this point.
	Z	Gets or sets the Z (third) coordinate of this point.

	Name	Description
	Add	Sums two Point4d together. (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 Point4d and has same coordinates as the present point. (Overrides ValueType.Equals(Object).)
	Equals(Point4d)	Determines whether the specified point has same value as the present point.
	GetHashCode	Computes the hash code for the present point. (Overrides ValueType.GetHashCode().)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Multiply	Multiplies a point by a number. (Provided for languages that do not support operator overloading. You can use the * operator otherwise)
	Subtract	Subtracts the second point from the first point. (Provided for languages that do not support operator overloading. You can use the - operator otherwise)
	ToString	Returns the fully qualified type name of this instance. (Inherited from ValueType.)

	Name	Description
	Addition	Sums two Point4d together.
	Equality	Determines whether two Point4d have equal values.
	Inequality	Determines whether two Point4d have different values.
	Multiply(Point4d, Point4d)	Multiplies two Point4d together, returning the dot (internal) product of the two. This is not the cross product.
	Multiply(Point4d, Double)	Multiplies a point by a number.
	Subtraction	Subtracts the second point from the first point.
