```

Represents the three coordinates of a point in three-dimensional space, using [float](https://learn.microsoft.com/dotnet/api/system.single)-precision floating point numbers.

## Constructors

- [Point3f](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.point3f/ctor.md): Initializes a new two-dimensional vector from two components.

## Properties

- [IsValid](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.point3f/isvalid.md): Each coordinate of the point must pass the [RhinoMath.IsValidSingle(float)](https://developer.rhino3d.com/api/rhinocommon/type/rhino.rhinomath/isvalidsingle.md) test.
- [Origin](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.point3f/origin.md): (static) Gets the value of a point at location 0,0,0.
- [Unset](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.point3f/unset.md): (static) Gets the value of a point at location RhinoMath.UnsetValue,RhinoMath.UnsetValue,RhinoMath.UnsetValue.
- [X](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.point3f/x.md): Gets or sets the X (first) component of the vector.
- [Y](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.point3f/y.md): Gets or sets the Y (second) component of the vector.
- [Z](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.point3f/z.md): Gets or sets the Z (third) component of the vector.

## Methods

- [Add](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.point3f/add.md): (3 overloads, static) 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)

Component evaluation priority is first X, then Y, then Z.
- [DistanceTo](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.point3f/distanceto.md): Computes the distance between two points.
- [DistanceToSquared](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.point3f/distancetosquared.md): Computes the squared distance between two points.
- [Divide](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.point3f/divide.md): (static) Divides a point by a factor. (Provided for languages that do not support operator overloading. You can use the / operator otherwise)
- [EpsilonEquals](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.point3f/epsilonequals.md): Check that all values in other are within epsilon of the values in this
- [Equals](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.point3f/equals.md): (2 overloads) Determines whether the specified System.Object is a Point3f and has the same values as the present point.
- [GetHashCode](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.point3f/gethashcode.md): Computes a hash code for the present point.
- [Multiply](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.point3f/multiply.md): (2 overloads, static) Multiplies a point by a factor. (Provided for languages that do not support operator overloading. You can use the * operator otherwise)
- [Negate](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.point3f/negate.md): (static) Computes the additive inverse of all coordinates in the point, and returns the new point. (Provided for languages that do not support operator overloading. You can use the - unary operator otherwise)
- [Subtract](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.point3f/subtract.md): (2 overloads, static) Subtracts a vector from a point. (Provided for languages that do not support operator overloading. You can use the - operator otherwise)
- [IComparable.CompareTo](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.point3f/system-icomparable-compareto.md)
- [ToString](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.point3f/tostring.md): (2 overloads) Constructs the string representation for the current point.
- [Transform](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.point3f/transform.md): Transforms the present point in place. The transformation matrix acts on the left of the point. i.e., result = transformation*point
