## Methods

- [AddToRhino](https://developer.rhino3d.com/api/gh2/type/grasshopper2.geometry.clustering.kdtree/addtorhino.md): Adds the first 3 dimensions of this tree to Rhino. This is for debugging purposes.
- [Find](https://developer.rhino3d.com/api/gh2/type/grasshopper2.geometry.clustering.kdtree/find.md): Find the closest point.
- [FindMultiple](https://developer.rhino3d.com/api/gh2/type/grasshopper2.geometry.clustering.kdtree/findmultiple.md): (3 overloads) Find the element(s) closest to a search point.
- [LeafMeans](https://developer.rhino3d.com/api/gh2/type/grasshopper2.geometry.clustering.kdtree/leafmeans.md): Return all leaf means.
- [MergeLeaves](https://developer.rhino3d.com/api/gh2/type/grasshopper2.geometry.clustering.kdtree/mergeleaves.md): Reduce the leaf count of this tree to a specific target.
- [Pull](https://developer.rhino3d.com/api/gh2/type/grasshopper2.geometry.clustering.kdtree/pull.md): Pull a collection of points onto the points.
- [SuperImpose](https://developer.rhino3d.com/api/gh2/type/grasshopper2.geometry.clustering.kdtree/superimpose.md): Find the closest point in another tree for every point in this tree.
