struct Ponca::KdTree< DataPoint >

Abstract KdTree type with KdTreeDefaultTraits.

Warning

It is not possible to create instances of type KdTree. This type must only be used to store pointers to KdTreeDense or KdTreeSparse objects, e.g. the declaration

    // Abstract pointer type that can receive KdTreeSparse or KdTreeDense objects
    KdTree<DataPoint> *kdtree {nullptr};

        // assign sparse
        kdtree = new KdTreeSparse<DataPoint> (points, sampling);

        // assign dense
        kdtree = new KdTreeDense<DataPoint> (points);
