## Functions

template<typename GridOrTreeT>
void | csgUnion (GridOrTreeT &a, GridOrTreeT &b, bool prune=true, bool pruneCancelledTiles=false)
| Given two level set grids, replace the A grid with the union of A and B.
template<typename GridOrTreeT>
void | csgIntersection (GridOrTreeT &a, GridOrTreeT &b, bool prune=true, bool pruneCancelledTiles=false)
| Given two level set grids, replace the A grid with the intersection of A and B.
template<typename GridOrTreeT>
void | csgDifference (GridOrTreeT &a, GridOrTreeT &b, bool prune=true, bool pruneCancelledTiles=false)
| Given two level set grids, replace the A grid with the difference A / B.
template<typename GridOrTreeT>
GridOrTreeT::Ptr | csgUnionCopy (const GridOrTreeT &a, const GridOrTreeT &b)
| Threaded CSG union operation that produces a new grid or tree from immutable inputs.
template<typename GridOrTreeT>
GridOrTreeT::Ptr | csgIntersectionCopy (const GridOrTreeT &a, const GridOrTreeT &b)
| Threaded CSG intersection operation that produces a new grid or tree from immutable inputs.
template<typename GridOrTreeT>
GridOrTreeT::Ptr | csgDifferenceCopy (const GridOrTreeT &a, const GridOrTreeT &b)
| Threaded CSG difference operation that produces a new grid or tree from immutable inputs.
template<typename GridOrTreeT>
void | compMax (GridOrTreeT &a, GridOrTreeT &b)
| Given grids A and B, compute max(a, b) per voxel (using sparse traversal). Store the result in the A grid and leave the B grid empty.
template<typename GridOrTreeT>
void | compMin (GridOrTreeT &a, GridOrTreeT &b)
| Given grids A and B, compute min(a, b) per voxel (using sparse traversal). Store the result in the A grid and leave the B grid empty.
template<typename GridOrTreeT>
void | compSum (GridOrTreeT &a, GridOrTreeT &b)
| Given grids A and B, compute a + b per voxel (using sparse traversal). Store the result in the A grid and leave the B grid empty.
template<typename GridOrTreeT>
void | compMul (GridOrTreeT &a, GridOrTreeT &b)
| Given grids A and B, compute a * b per voxel (using sparse traversal). Store the result in the A grid and leave the B grid empty.
template<typename GridOrTreeT>
void | compDiv (GridOrTreeT &a, GridOrTreeT &b)
| Given grids A and B, compute a / b per voxel (using sparse traversal). Store the result in the A grid and leave the B grid empty.
template<typename GridOrTreeT>
void | compReplace (GridOrTreeT &a, const GridOrTreeT &b)
| Copy the active voxels of B into A.
template<typename T>
const std::enable_if<!VecTraits< T >::IsVec, T >::type & | min (const T &a, const T &b)
template<typename T>
const std::enable_if<!VecTraits< T >::IsVec, T >::type & | max (const T &a, const T &b)
template<typename T>
const std::enable_if< VecTraits< T >::IsVec, T >::type & | min (const T &a, const T &b)
template<typename T>
const std::enable_if< VecTraits< T >::IsVec, T >::type & | max (const T &a, const T &b)
template<typename T>
std::enable_if<!std::is_integral< T >::value, T >::type | divide (const T &a, const T &b)
template<typename T>
std::enable_if< std::is_integral< T >::value, T >::type | divide (const T &a, const T &b)
bool | divide (bool a, bool)
template<typename TreeT, typename OpT = composite::CopyOp<TreeT>>
void | compActiveLeafVoxels (TreeT &srcTree, TreeT &dstTree, OpT op=composite::CopyOp< TreeT >())
| Composite the active values in leaf nodes, i.e. active voxels, of a source tree into a destination tree.
