Detailed Description

template<typename TreeT, bool Union>
struct openvdb::v13_0::tools::CsgUnionOrIntersectionOp< TreeT, Union >

DynamicNodeManager operator to merge trees using a CSG union or intersection.

Note

This class modifies the topology of the tree so is designed to be used from DynamicNodeManager::foreachTopDown().

A union and an intersection are opposite operations to each other so implemented in a combined class. Use the CsgUnionOp and CsgIntersectionOp aliases for convenience.

Constructor & Destructor Documentation

CsgUnionOrIntersectionOp ( TreeT &  tree, TagT  tag  )

inline

Convenience constructor to CSG union or intersect a single non-const tree with another. This constructor takes a Steal or DeepCopy tag dispatch class.

CsgUnionOrIntersectionOp ( const TreeT &  tree, DeepCopy  tag  )

inline

Convenience constructor to CSG union or intersect a single const tree with another. This constructor requires a DeepCopy tag dispatch class.

CsgUnionOrIntersectionOp ( TreesT &  trees, TagT  tag  )

inline

Constructor to CSG union or intersect a container of multiple const or non-const tree pointers. A Steal tag requires a container of non-const trees, a DeepCopy tag will accept either const or non-const trees.

CsgUnionOrIntersectionOp ( const std::vector< TreeToMerge< TreeT >> &  trees )

inlineexplicit

Constructor to accept a vector of TreeToMerge objects, primarily used when mixing const/non-const trees.

Note

Union/intersection order is preserved.

CsgUnionOrIntersectionOp ( const std::deque< TreeToMerge< TreeT >> &  trees )

inlineexplicit

Constructor to accept a deque of TreeToMerge objects, primarily used when mixing const/non-const trees.

Note

Union/intersection order is preserved.
