Public Property
Static Member

Origin

Gets the value of a point at location 0,0,0.

Public Property
Static Member

Unset

Gets the value of a point at location RhinoMath.UnsetValue,RhinoMath.UnsetValue,RhinoMath.UnsetValue.

Public Property

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

Public Property

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

Methods

Name

Description

Public Method

CompareTo

Compares this Point3f with another Point3f.

Component evaluation priority is first X, then Y, then Z.

Public Method
Code Example

DistanceTo

Computes the distance between two points.

Public Method

DistanceToSquared

Computes the squared distance between two points.

Public Method

EpsilonEquals

Check that all values in other are within epsilon of the values in this

Public Method

Equals(Object)

Determines whether the specified System.Object is a Point3f and has the same values as the present point.

(Overrides ValueType.Equals(Object).)

Public Method

Equals(Point3f)

Determines whether the specified Point3f has the same values as the present point.

Public Method

GetHashCode

Computes a hash code for the present point.

(Overrides ValueType.GetHashCode..)

Public Method

GetType

Gets the Type of the current instance.

(Inherited from Object.)

Public Method
Static Member

Subtract

Subtracts a point from another point.

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

Public Method

ToString.

Constructs the string representation for the current point.

(Overrides ValueType.ToString..)

Public Method

ToString(String, IFormatProvider)

Formats the value of the current instance using the specified format.

Public Method

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

Public Operator
Static Member
Addition

Adds a point to another point.

Public Operator
Static Member
Equality

Determines whether two points have equal values.

Public Operator
Static Member
.(Point3d to Point3f)

Converts a double-precision point in a single-precision point. Needs explicit casting to help retain precision.

Public Operator
Static Member
.(Point3f to Vector3f)

Converts a single-precision point in a single-precision vector. Needs explicit casting to help retain precision.

Public Operator
Static Member
GreaterThan

Determines whether the first specified point comes after (has superior sorting value than) the second point.

Coordinates evaluation priority is first X, then Y, then Z.

Public Operator
Static Member
GreaterThanOrEqual

Determines whether the first specified point comes after (has superior sorting value than) the second point, or it is equal to it.

Coordinates evaluation priority is first X, then Y, then Z.

Public Operator
Static Member
Inequality

Determines whether two points have different values.

Public Operator
Static Member
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, then Z.

Public Operator
Static Member
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, then Z.

Public Operator
Static Member
Multiply(Point3f, Single)

Multiplies a point by a factor.

Public Operator
Static Member
Multiply(Single, Point3f)

Multiplies a point by a factor.

Public Operator
Static Member
Subtraction

Subtracts a point from another point.
