Vector2d

Vector2d struct

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

Derived Classes:

Namespace: Rhino.Geometry
Vector2d: references

Constructors (1)

Vector2d(double x, double y)

Initializes a new instance of the vector based on two, X and Y, components.

Properties (7)

IsValid

Gets a value indicating whether this vector is valid. A valid vector must be formed of valid component values for x, y and z.

Length

Computes the length (or magnitude, or size) of this vector. This is an application of Pythagoras' theorem.

SquareLength

Returns the square of the length of the vector.

Unset

Gets the value of the vector with components set as RhinoMath.UnsetValue,RhinoMath.UnsetValue.

Gets or sets the X (first) component of this vector.

Gets or sets the Y (second) component of this vector.

Zero

Gets the value of the vector with components 0,0.

Methods (18)

Add(Vector2d vector1, Vector2d vector2)

Sums up two vectors.
(Provided for languages that do not support operator overloading. You can use the + operator otherwise)

CompareTo(Vector2d other)

Compares this Vector2d with another Vector2d .
Components evaluation priority is first X, then Y.

Divide(Vector2d vector, double t)

Divides a Vector2d by a number, having the effect of shrinking it.
(Provided for languages that do not support operator overloading. You can use the / operator otherwise)

EpsilonEquals(Vector2d 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 Vector2d and has the same value as the present vector.

Equals(Vector2d vector)

Determines whether the specified vector has the same value as the present vector.

GetHashCode()

Provides a hashing value for the present vector.

IsTiny()

Uses RhinoMath.ZeroTolerance for IsTiny calculation.

IsTiny(double tolerance)

Determines whether a vector is very short.

Multiply(double t, Vector2d vector)

Multiplies a vector by a number, having the effect of scaling it.
(Provided for languages that do not support operator overloading. You can use the * operator otherwise)

Multiply(Vector2d vector, double t)

Multiplies a vector by a number, having the effect of scaling it.
(Provided for languages that do not support operator overloading. You can use the * operator otherwise)

Multiply(Vector2d vector1, Vector2d vector2)

Multiplies two vectors together, returning the dot product (or inner product).
(Provided for languages that do not support operator overloading. You can use the * operator otherwise)

Negate(Vector2d vector)

Computes the reversed vector.
(Provided for languages that do not support operator overloading. You can use the - unary operator otherwise)

Rotate(double angleRadians)

Rotates this vector.

Subtract(Vector2d vector1, Vector2d vector2)

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

ToString()

Constructs a string representation of the current vector.

ToString(string format,IFormatProvider formatProvider)

Unitize()

Unitizes the vector in place. A unit vector has length 1 unit.
An invalid or zero length vector cannot be unitized.

Operators (13)

Computes the opposite vector.

Subtracts the second vector from the first one.

Determines whether two vectors have different values.

Multiplies two vectors together, returning the dot product (or inner product).

Multiplies a vector by a number, having the effect of scaling it.

Divides a Vector2d by a number, having the effect of shrinking it.

Sums up two vectors.

Determines whether the first specified vector comes before (has inferior sorting value than) the second vector.
Components have decreasing evaluation priority: first X, then Y.

Determines whether the first specified vector comes before (has inferior sorting value than) the second vector, or it is equal to it.
Components have decreasing evaluation priority: first X, then Y.

Determines whether two vectors have equal values.

Determines whether the first specified vector comes after (has superior sorting value than) the second vector.
Components have decreasing evaluation priority: first X, then Y.

Determines whether the first specified vector comes after (has superior sorting value than) the second vector, or it is equal to it.
Components have decreasing evaluation priority: first X, then Y.
