public PolyhedronsSet(BSPTree<Euclidean3D> tree)
The leaf nodes of the BSP tree must have a Boolean attribute representing the inside status of
the corresponding cell (true for inside cells, false for outside cells). In order to avoid building too many
small objects, it is recommended to use the predefined constants Boolean.TRUE and Boolean.FALSE
tree - inside/outside BSP tree representing the regionpublic PolyhedronsSet(Collection<SubHyperplane<Euclidean3D>> boundary)
The boundary is provided as a collection of sub-hyperplanes. Each sub-hyperplane has the
interior part of the region on its minus side and the exterior on its plus side.
The boundary elements can be in any order, and can form several non-connected sets (like for example polyhedrons
with holes or a set of disjoint polyhedrons considered as a whole). In fact, the elements do not even need to be
connected together (their topological connections are not used here). However, if the boundary does not really
separate an inside open from an outside open (open having here its topological meaning), then subsequent calls to
the checkPoint method will not be meaningful anymore.
If the boundary is empty, the region will represent the whole space.

This method allow to create new instances without knowing exactly the type of the region. It is an application of the prototype design pattern.
The leaf nodes of the BSP tree must have a Boolean attribute representing the inside status of
the corresponding cell (true for inside cells, false for outside cells). In order to avoid building too many
small objects, it is recommended to use the predefined constants Boolean.TRUE and Boolean.FALSE.
The tree also must have either null internal nodes or internal nodes representing the boundary as
specified in the getTree method).
