struct flecsi::util::KDTree< DIM >

A k-d tree for efficiently finding intersections between shapes.

Member Typedef Documentation

boxes

template<Dimension DIM>

using boxes

Type alias for a vector of Bounding Boxes.

overlap

template<Dimension DIM>

using overlap

The leaves of another tree that intersect each leaf of a given tree.

Constructor & Destructor Documentation

KDTree()

template<Dimension DIM>

KDTree

(

const boxes &

sboxp

)

Construct the tree from leaf bounding boxes.

Parameters

sboxp

vector of safety boxes

Member Function Documentation

intersect()

template<Dimension DIM>

KDTree< DIM >::overlap intersect

(

const KDTree< DIM > &

k

)

const

Find intersections between this tree and another.

A possible use case is finding the overlap between multiple distributed meshes .

Returns

mapping from the this tree's leaves to vectors of intersecting leaves in k
