Point2d Structure 
Namespace: Rhino.Geometry
The Point2d type exposes the following members.
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.

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.

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 
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) 
Multiplies a Point2d by a number.
 
Multiply(Point2d, Double) 
Multiplies a Point2d by a number.
 
Subtraction(Point2d, Point2d) 
Subtracts point2 from point1.
 
Subtraction(Point2d, Vector2d) 
Subtracts a vector from a point.
