Detailed Description

bounding volume hierarchy for point cloud structure

Member Typedef Documentation

NodeBitSet

using MR::AABBTreePoints::NodeBitSet = TaggedBitSet<NodeTag>

NodeVec

using MR::AABBTreePoints::NodeVec = Vector<Node, NodeId>

Constructor & Destructor Documentation

AABBTreePoints() [1/5]

MRMESH_API MR::AABBTreePoints::AABBTreePoints

(

const PointCloud &

pointCloud

)

creates tree for given point cloud

AABBTreePoints() [2/5]

MRMESH_API MR::AABBTreePoints::AABBTreePoints

(

const Mesh &

mesh

)

creates tree for vertices of given mesh

AABBTreePoints() [3/5]

MRMESH_API MR::AABBTreePoints::AABBTreePoints	(	const VertCoords &	points,
		const VertBitSet *	validPoints = nullptr )

creates tree from given valid points

AABBTreePoints() [4/5]

MR::AABBTreePoints::AABBTreePoints ( const VertCoords & points, const VertBitSet & validPoints )

inline

creates tree from given valid points

AABBTreePoints() [5/5]

MR::AABBTreePoints::AABBTreePoints ( AABBTreePoints && )

Member Function Documentation

getBoundingBox()

Box3f MR::AABBTreePoints::getBoundingBox ( ) const

inlinenodiscard

returns the root node bounding box

getLeafOrder()

MRMESH_API void MR::AABBTreePoints::getLeafOrder

(

VertBMap &

vertMap

)

const

returns the mapping original VertId to new id following the points order in the tree; buffer in vertMap must be resized before the call, and caller is responsible for filling missing vertex elements

getLeafOrderAndReset()

MRMESH_API void MR::AABBTreePoints::getLeafOrderAndReset

(

VertBMap &

vertMap

)

returns the mapping original VertId to new id following the points order in the tree; then resets leaf order as if the points were renumberd following the mapping; buffer in vertMap must be resized before the call, and caller is responsible for filling missing vertex elements

heapBytes()

MRMESH_API size_t MR::AABBTreePoints::heapBytes ( ) const

nodiscard

returns the amount of memory this object occupies on heap

nodes()

const NodeVec & MR::AABBTreePoints::nodes ( ) const

inlinenodiscard

operator=()

AABBTreePoints & MR::AABBTreePoints::operator= ( AABBTreePoints && )

defaultnoexcept

operator[]()

const Node & MR::AABBTreePoints::operator[] ( NodeId nid ) const

inlinenodiscard

orderedPoints()

const std::vector< Point > & MR::AABBTreePoints::orderedPoints ( ) const

inlinenodiscard

refit()

MRMESH_API void MR::AABBTreePoints::refit	(	const VertCoords &	newCoords,
		const VertBitSet &	changedVerts )

updates bounding boxes of the nodes containing changed vertices; this is a faster alternative to full tree rebuild (but the tree after refit might be less efficient)

Parameters

newCoords	coordinates of all vertices including changed ones;
changedVerts	vertex ids with modified coordinates (since tree construction or last refit)

rootNodeId()

static NodeId MR::AABBTreePoints::rootNodeId ( )

inlinestaticnodiscard

Member Data Documentation

MaxNumPointsInLeaf

int MR::AABBTreePoints::MaxNumPointsInLeaf = 16
