Member Typedef Documentation

◆ AabbType

template<typename _DataPoint >

using Ponca::KnnGraphPointerTraits< _DataPoint >::AabbType = Eigen::AlignedBox<Scalar, DataPoint::Dim>

The type used to calculate node bounding boxes.

Must provide min(), max(), and center() functions, all returning a VectorType.

Definition at line 103 of file knnGraphTraits.h.

◆ DataPoint

template<typename _DataPoint >

using Ponca::KnnGraphPointerTraits< _DataPoint >::DataPoint = _DataPoint

The type used to store point data.

Must provide Scalar and VectorType aliases.

VectorType must provide a squaredNorm() function returning a Scalar, as well as a maxCoeff(int*) function returning the dimension index of its largest scalar in its output parameter (e.g. 0 for x, 1 for y, etc.).
