Struct GeoVector2D

A two dimensional vector with double x and y components. Keep in mind that this is a value type. Passing a value type as a (non ref) parameter and changing it's value inside the invoked method leaves the original unchanged.

Methods

Area(GeoVector2D, GeoVector2D)

Returns the area of the parallelogram defined by the two vectors. The result will be positive if the sweep-direction from from to to is counterclockwise otherwise it will be negative. If you need the angle of the triangle divide the result by 2.0

Declaration

public static double Area(GeoVector2D from, GeoVector2D to)

Parameters

Type	Name	Description
GeoVector2D	from	First vector
GeoVector2D	to	Second vector

Returns

Type	Description
System.Double	the area

Cos(GeoVector2D, GeoVector2D)

Returns the cosine of the angle between the two vectors. Throws an arithmetic exception if any of the vectors is the nullvector.

Declaration

public static double Cos(GeoVector2D v1, GeoVector2D v2)

Parameters

Type	Name	Description
GeoVector2D	v1	First vector
GeoVector2D	v2	Second vector

Returns

Type	Description
System.Double	Cosine of the inner angle

Declaration

public void GetObjectData(SerializationInfo info, StreamingContext context)

Parameters

Type	Name	Description
System.Runtime.Serialization.SerializationInfo	info	The System.Runtime.Serialization.SerializationInfo to populate with data.
System.Runtime.Serialization.StreamingContext	context	The destination (System.Runtime.Serialization.StreamingContext) for this serialization.

Orientation(GeoVector2D, GeoVector2D)

Returns a positive value if the second vector turns to the left relative to the direction of the first vector, a negative value if it turns to the right and 0.0 if the vectors are parallel. The value is the length of the crossproduct of the two vectors in 3D or the area of the parallelogram build by the two vectors.

Declaration

public static double Orientation(GeoVector2D v1, GeoVector2D v2)

Parameters

Type	Name	Description
GeoVector2D	v1	First vector
GeoVector2D	v2	Second vector

Returns

Type	Description
System.Double	The orientation
