Exposes a set of standard numeric interpolation algorithms.

## Constructors

- [Interpolator](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.interpolator/ctor.md): (5 overloads) Constructs a new, empty Interpolator.

## Properties

- [Cyclical](https://developer.rhino3d.com/api/rhinocommon/type/rhino.geometry.interpolator/cyclical.md): Gets or sets a value indicating whether or not the values inside this Interpolator are to be treated as cyclical (i.e. circular).
