Represents the three coordinates of a point in three-dimensional space, using Double-precision floating point values.

Namespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll)

Syntax

[SerializableAttribute]
public struct Point3d : ISerializable, IEquatable<Point3d>, 
	IComparable<Point3d>, IComparable, IEpsilonComparable<Point3d>, 
	ICloneable, IFormattable

<SerializableAttribute>
Public Structure Point3d
	Implements ISerializable, IEquatable(Of Point3d), 
	IComparable(Of Point3d), IComparable, IEpsilonComparable(Of Point3d), 
	ICloneable, IFormattable

The Point3d type exposes the following members.

Constructors

	Name	Description
	Point3d(Point3d)	Initializes a new point by copying coordinates from another point.
	Point3d(Point3f)	Initializes a new point by copying coordinates from a single-precision point.
	Point3d(Point4d)	Initializes a new point by copying coordinates from a four-dimensional point. The first three coordinates are divided by the last one. If the W (fourth) dimension of the input point is zero, then it will be just discarded.
	Point3d(Vector3d)	Initializes a new point by copying coordinates from the components of a vector.
	Point3d(Double, Double, Double)	Initializes a new point by defining the X, Y and Z coordinates.

Properties

	Name	Description
	IsValid	Each coordinate of the point must pass the IsValidDouble(Double) test.
	Item	Gets or sets an indexed coordinate of this point.
	MaximumCoordinate	Gets the largest (both positive and negative) valid coordinate in this point, or RhinoMath.UnsetValue if no coordinate is valid, as an absolute value.
	MinimumCoordinate	Gets the smallest (both positive and negative) coordinate value in this point.
	Origin	Gets the value of a point at location 0,0,0.
	Unset	Gets the value of a point at location RhinoMath.UnsetValue,RhinoMath.UnsetValue,RhinoMath.UnsetValue.
	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.

Methods

	Name	Description
	Add(Point3d, Point3d)	Sums two Point3d instances. (Provided for languages that do not support operator overloading. You can use the + operator otherwise)
	Add(Point3d, Vector3d)	Sums up a point and a vector, and returns a new point. (Provided for languages that do not support operator overloading. You can use the + operator otherwise)
	Add(Point3d, Vector3f)	Sums up a point and a vector, and returns a new point. (Provided for languages that do not support operator overloading. You can use the + operator otherwise)
	Add(Vector3d, Point3d)	Sums up a point and a vector, and returns a new point. (Provided for languages that do not support operator overloading. You can use the + operator otherwise)
	ArePointsCoplanar	Determines whether a set of points is coplanar within a given tolerance.
	CompareTo	Compares this Point3d with another Point3d. Component evaluation priority is first X, then Y, then Z.
	CullDuplicates	Removes duplicates in the supplied set of points.
	DistanceTo	Computes the distance between two points.
	DistanceToSquared	Computes the square of the distance between two points. This method is usually largely faster than DistanceTo().
	Divide	Divides a Point3d by a number. (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 Object is a Point3d and has the same values as the present point. (Overrides ValueTypeEquals(Object).)
	Equals(Point3d)	Determines whether the specified Point3d has the same values as the present point.
	FromPoint3f	Converts a single-precision point in a double-precision point.
	GetHashCode	Computes a hash code for the present point. (Overrides ValueTypeGetHashCode.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Interpolate	Interpolate between two points.
	Multiply(Double, Point3d)	Multiplies a Point3d by a number. (Provided for languages that do not support operator overloading. You can use the * operator otherwise)
	Multiply(Point3d, Double)	Multiplies a Point3d by a number. (Provided for languages that do not support operator overloading. You can use the * operator otherwise)
	SortAndCullPointList	Orders a set of points so they will be connected in a "reasonable polyline" order. Also, removes points from the list if their common distance exceeds a specified threshold.
	Subtract(Point3d, Point3d)	Subtracts a point from another point. (Provided for languages that do not support operator overloading. You can use the - operator otherwise)
	Subtract(Point3d, Vector3d)	Subtracts a vector from a point. (Provided for languages that do not support operator overloading. You can use the - operator otherwise)
	ToString	Constructs the string representation for the current point. (Overrides ValueTypeToString.)
	ToString(String, IFormatProvider)	Formats the value of the current instance using the specified format.
	Transform	Transforms the present point in place. The transformation matrix acts on the left of the point. i.e., result = transformation*point
	TryParse	Converts the string representation of a point to the equivalent Point3d structure.
