Vector3f

Vector3f struct

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

Derived Classes:

Namespace: Rhino.Geometry
Vector3f: references

Constructors (1)

Vector3f(float x, float y, float z)

Constructs a new vector from 3 single precision numbers.

Properties (13)

IsUnitVector

Gets a value indicating whether or not this is a unit vector. A unit vector has length 1.

IsValid

Returns an indication regarding the validity of this vector.

IsZero

Gets a value indicating whether the X, Y, and Z values are all equal to 0.0.

Length

Computes the length (or magnitude, or size) of this vector. This is an application of Pythagoras' theorem. If this vector is invalid, its length is considered 0.

SquareLength

Returns the square length of the vector. This property does not check for the validity of the inputs.

Unset

Gets the value of the vector with each component set to RhinoMath.UnsetValue.

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

XAxis

Gets the value of the vector with components 1,0,0.

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

YAxis

Gets the value of the vector with components 0,1,0.

Gets or sets the Z (third) component of this vector.

ZAxis

Gets the value of the vector with components 0,0,1.

Zero

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

Methods (22)

Add(Point3f point, Vector3f vector)

Sums up a point and a vector, and returns a new point.
(Provided for languages that do not support operator overloading. You can use the + operator otherwise)

Add(Vector3f vector1, Vector3f vector2)

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

CompareTo(Vector3f other)

Compares this Vector3f with another Vector3f .
Component evaluation priority is first X, then Y, then Z.

CrossProduct(Vector3f a, Vector3f b)

Computes the cross product (or vector product, or exterior product) of two vectors.
This operation is not commutative.

Divide(Vector3f vector, double t)

Divides a Vector3f by a number, having the effect of shrinking it, t times.
(Provided for languages that do not support operator overloading. You can use the / operator otherwise)

Divide(Vector3f vector, float t)

Divides a Vector3f by a number, having the effect of shrinking it, t times.
(Provided for languages that do not support operator overloading. You can use the / operator otherwise)

EpsilonEquals(Vector3f other, float 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 Vector3f and has the same values as the present vector.

Equals(Vector3f vector)

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

GetHashCode()

Computes a hash number that represents the current vector.

Multiply(float t, Vector3f 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(Vector3f point1, Vector3f point2)

Multiplies two Vector3f together, returning the dot (internal) product of the two. This is not the cross product.
(Provided for languages that do not support operator overloading. You can use the * operator otherwise)

Multiply(Vector3f vector, float 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)

Negate(Vector3f vector)

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

PerpendicularTo(Vector3f other)

Sets this vector to be perpendicular to another vector. Result is not unitized.

Reverse()

Reverses this vector in place (reverses the direction).
If this vector contains RhinoMath.UnsetValue, the reverse will also be invalid and False will be returned.

Rotate(double angleRadians, Vector3f rotationAxis)

Rotates this vector around a given axis.

Subtract(Vector3f vector1, Vector3f 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 the string representation of the current vector.

ToString(string format,IFormatProvider formatProvider)

Transform(Transform transformation)

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

Unitize()

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

Operators (15)

Computes the opposite vector.

Subtracts the second vector from the first one.

Determines whether two vectors have different values.

Multiplies two Vector3f together, returning the dot (internal) product of the two. This is not the cross product.

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

Divides a Vector3f by a number, having the effect of shrinking it, t times.

Sums up a point and a vector, and returns a new point.

Sums up two vectors.

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

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

Determines whether two vectors have equal values.

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

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