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