Syntax[SerializableAttribute] public struct Point2d : ISerializable, IEquatable<Point2d>, IComparable<Point2d>, IComparable, IEpsilonComparable<Point2d>
<SerializableAttribute> Public Structure Point2d Implements ISerializable, IEquatable(Of Point2d), IComparable(Of Point2d), IComparable, IEpsilonComparable(Of Point2d)
The Point2d type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | Point2d(Point2d) |
Initializes a new instance of Point2d by copying another Point2d.
|
| Point2d(Point3d) | |
| Point2d(Vector2d) |
Initializes a new instance of Point2d by converting a vector.
|
| Point2d(Double, Double) |
Initializes a new instance of Point2d from coordinates.
|
Properties| Name | Description | |
|---|---|---|
 | 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.
|
| X |
Gets or sets the X (first) coordinate of the point.
|
| Y |
Gets or sets the Y (second) coordinate of the point.
|
Methods| Name | Description | |
|---|---|---|
| Add(Point2d, Point2d) |
Adds a point with a point.
(Provided for languages that do not support operator overloading. You can use the + operator otherwise) |
| Add(Point2d, Vector2d) |
Adds a point with a vector.
(Provided for languages that do not support operator overloading. You can use the + operator otherwise) |
| Add(Vector2d, Point2d) |
Adds a vector with a point.
(Provided for languages that do not support operator overloading. You can use the + operator otherwise) |
| CompareTo |
Compares this Point2d with another Point2d.
Coordinates evaluation priority is first X, then Y. |
 | DistanceTo |
Computes the distance between two points.
|
| Divide |
Divides a Point2d 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 System.Object is a Point2d and has the same values as the present point.
(Overrides ValueTypeEquals(Object).) |
| Equals(Point2d) |
Determines whether the specified Point2d has the same values as the present point.
|
| GetHashCode |
Computes a hash number that represents the current point.
(Overrides ValueTypeGetHashCode.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| Multiply(Double, Point2d) |
Multiplies a Point2d by a number.
(Provided for languages that do not support operator overloading. You can use the * operator otherwise) |
| Multiply(Point2d, Double) |
Multiplies a Point2d by a number.
(Provided for languages that do not support operator overloading. You can use the * operator otherwise) |
| Subtract(Point2d, Point2d) |
Subtracts the second point from the first point.
(Provided for languages that do not support operator overloading. You can use the - operator otherwise) |
| Subtract(Point2d, Vector2d) |
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.) |
| Transform |
Transforms the present point in place. The transformation matrix acts on the left of the point. i.e.,
result = transformation*point |
Operators| Name | Description | |
|---|---|---|
 | Addition(Point2d, Point2d) |
Adds a point with a point.
|
| Addition(Point2d, Vector2d) |
Adds a point with a vector.
|
| Addition(Vector2d, Point2d) |
Adds a vector with a point.
|
| Division |
Divides a Point2d by a number.
|
| Equality |
Determines whether two Point2d have equal values.
|
| GreaterThan |
Determines whether the first specified Point2d comes after
(has superior sorting value than) the second point.
Coordinates evaluation priority is first X, then Y. |
| GreaterThanOrEqual |
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. |
| Inequality |
Determines whether two Point2d have different values.
|
| LessThan |
Determines whether the first specified point comes before (has inferior sorting value than) the second point.
Coordinates evaluation priority is first X, then Y. |
| LessThanOrEqual |
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. |
| Multiply(Double, Point2d) |

|
| Subtraction(Point2d, Point2d) |
Subtracts point2 from point1.
|
| Subtraction(Point2d, Vector2d) |
Subtracts a vector from a point.
