Constructor & Destructor Documentation

AABBTree() [1/3]

MRMESH_API MR::AABBTree::AABBTree ( const MeshPart & mp )

explicitnodiscard

creates tree for given mesh or its part

AABBTree() [2/3]

MR::AABBTree::AABBTree ( )

default

AABBTree() [3/3]

MR::AABBTree::AABBTree ( AABBTree && )

defaultnoexcept

Member Function Documentation

operator=()

AABBTree & MR::AABBTree::operator= ( AABBTree && )

defaultnoexcept

refit()

MRMESH_API void MR::AABBTree::refit	(	const Mesh &	mesh,
		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

mesh	same mesh for which this tree was constructed but with updated coordinates;
changedVerts	vertex ids with modified coordinates (since tree construction or last refit)
