Point2d

Point2d struct

Represents the two coordinates of a point in two-dimensional space, using double -precision floating point numbers.

Derived Classes:

Namespace: Rhino.Geometry
Point2d: references

Constructors (4)

Point2d(double x, double y)

Initializes a new instance of Point2d from coordinates.

Point2d(Point2d point)

Initializes a new instance of Point2d by copying another Point2d .

Point2d(Point3d point)

Initializes a new instance of Point3d by copying the first two coordinates of a Point3d .

Point2d(Vector2d vector)

Initializes a new instance of Point2d by converting a vector.

Properties (8)

IsValid

If any coordinate of a point is UnsetValue, then the point is not valid.

Item

Accesses the coordinates of this point.

MaximumCoordinate

Gets the largest valid coordinate, or RhinoMath.UnsetValue if no coordinate is valid.

MinimumCoordinate

Gets the smallest (both positive and negative) valid coordinate, or RhinoMath.UnsetValue if no coordinate is valid.

Origin

Gets a point at 0,0.

Unset

Gets a point at RhinoMath.UnsetValue,RhinoMath.UnsetValue.

Gets or sets the X (first) coordinate of the point.

Gets or sets the Y (second) coordinate of the point.

Methods (18)

Add(Point2d point, Vector2d vector)

Adds a point with a vector.
(Provided for languages that do not support operator overloading. You can use the + operator otherwise)

Add(Point2d point1, Point2d point2)

Adds a point with a point.
(Provided for languages that do not support operator overloading. You can use the + operator otherwise)

Add(Vector2d vector, Point2d point)

Adds a vector with a point.
(Provided for languages that do not support operator overloading. You can use the + operator otherwise)

CompareTo(Point2d other)

Compares this Point2d with another Point2d .
Coordinates evaluation priority is first X, then Y.

DistanceTo(Point2d other)

Computes the distance between two points.

DistanceToSquared(Point2d other)

Computes the square of the distance between two 2d points.
This method is usually largely faster than DistanceTo().

Divide(Point2d point, double t)

Divides a Point2d by a number.
(Provided for languages that do not support operator overloading. You can use the / operator otherwise)

EpsilonEquals(Point2d other, double epsilon)

Check that all values in other are within epsilon of the values in this

Equals(object obj)

Determines whether the specified System.Object is a Point2d and has the same values as the present point.

Equals(Point2d point)

Determines whether the specified Point2d has the same values as the present point.

GetHashCode()

Computes a hash number that represents the current point.

Multiply(double t, Point2d point)

Multiplies a Point2d by a number.
(Provided for languages that do not support operator overloading. You can use the * operator otherwise)

Multiply(Point2d point, double t)

Multiplies a Point2d by a number.
(Provided for languages that do not support operator overloading. You can use the * operator otherwise)

Subtract(Point2d point, Vector2d vector)

Subtracts a vector from a point.
(Provided for languages that do not support operator overloading. You can use the - operator otherwise)

Subtract(Point2d point1, Point2d point2)

Subtracts the second point from the first 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.

ToString(string format,IFormatProvider formatProvider)

Transform(Transform xform)

Transforms the present point in place. The transformation matrix acts on the left of the point. i.e.,
result = transformation*point

Operators (14)

Subtracts a vector from a point.

Subtracts point2 from point1.

Determines whether two Point2d have different values.

Multiplies a Point2d by a number.

Divides a Point2d by a number.

Adds a point with a vector.

Adds a point with a point.

Adds a vector with a point.

Determines whether the first specified point comes before (has inferior sorting value than) the second point.
Coordinates evaluation priority is first X, then Y.

Determines whether the first specified point comes before (has inferior sorting value than) the second point, or it is equal to it.
Coordinates evaluation priority is first X, then Y.

Determines whether two Point2d have equal values.

Determines whether the first specified Point2d comes after (has superior sorting value than) the second point.
Coordinates evaluation priority is first X, then Y.

Determines whether the first specified Point2d comes after (has superior sorting value than) the second point, or it is equal to it.
Coordinates evaluation priority is first X, then Y.
