template<typename GridOrTreeType >
GridOrTreeType::template ValueConverter< bool >::Type::Ptr	extractEnclosedRegion (const GridOrTreeType &volume, typename GridOrTreeType::ValueType isovalue=lsutilGridZero< GridOrTreeType >(), const typename TreeAdapter< GridOrTreeType >::TreeType::template ValueConverter< bool >::Type *fillMask=nullptr)
	Extracts the interior regions of a signed distance field and topologically enclosed (watertight) regions of value greater than the isovalue (cavities) that can arise as the result of CSG union operations between different shapes where at least one of the shapes has a concavity that is capped.
