Member Function Documentation

getBoundingBox()

template<typename T >

BoxT MR::AABBTreeBase< T >::getBoundingBox ( ) const

inlinenodiscard

returns the root node bounding box

getLeafOrder()

template<typename T >

MRMESH_API void MR::AABBTreeBase< T >::getLeafOrder

(

LeafBMap &

leafMap

)

const

fills map: LeafId -> leaf#; buffer in leafMap must be resized before the call, and caller is responsible for filling missing leaf elements

getLeafOrderAndReset()

template<typename T >

MRMESH_API void MR::AABBTreeBase< T >::getLeafOrderAndReset

(

LeafBMap &

leafMap

)

fills map: LeafId -> leaf#, then resets leaf order to 0,1,2,...; buffer in leafMap must be resized before the call, and caller is responsible for filling missing leaf elements

getNodesFromLeaves()

template<typename T >

MRMESH_API NodeBitSet MR::AABBTreeBase< T >::getNodesFromLeaves ( const LeafBitSet & leaves ) const

nodiscard

returns set of nodes containing among direct or indirect children given leaves

getSubtreeLeaves()

template<typename T >

MRMESH_API LeafBitSet MR::AABBTreeBase< T >::getSubtreeLeaves ( NodeId subtreeRoot ) const

nodiscard

returns all leaves in the subtree with given root

getSubtrees()

template<typename T >

MRMESH_API std::vector< NodeId > MR::AABBTreeBase< T >::getSubtrees ( int minNum ) const

nodiscard

returns at least given number of top-level not-intersecting subtrees, union of which contain all tree leaves

heapBytes()

template<typename T >

MRMESH_API size_t MR::AABBTreeBase< T >::heapBytes ( ) const

inlinenodiscard

returns the amount of memory this object occupies on heap

nodes()

template<typename T >

const NodeVec & MR::AABBTreeBase< T >::nodes ( ) const

inlinenodiscard

const-access to all nodes

numLeaves()

template<typename T >

size_t MR::AABBTreeBase< T >::numLeaves ( ) const

inlinenodiscard

returns the number of leaves in whole tree

operator[]()

template<typename T >

const Node & MR::AABBTreeBase< T >::operator[] ( NodeId nid ) const

inlinenodiscard

const-access to any node

rootNodeId()

template<typename T >

static NodeId MR::AABBTreeBase< T >::rootNodeId ( )

inlinestaticnodiscard

returns root node id
