public PolyhedronsSet(double tolerance)
tolerance
 tolerance below which points are considered identicalpublic PolyhedronsSet(BSPTree<Euclidean3D> tree, double tolerance)
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
This constructor is aimed at expert use, as building the tree may
be a difficult task. It is not intended for general use and for
performances reasons does not check thoroughly its input, as this would
require walking the full tree each time. Failing to provide a tree with
the proper attributes, will therefore generate problems like
NullPointerException
or ClassCastException
only later on.
This limitation is known and explains why this constructor is for expert
use only. The caller does have the responsibility to provided correct arguments.
tree
 inside/outside BSP tree representing the regiontolerance
 tolerance below which points are considered identicalpublic PolyhedronsSet(Collection<SubHyperplane<Euclidean3D>> boundary, double tolerance)
The boundary is provided as a collection of subhyperplanes
. Each subhyperplane 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 nonconnected 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.

The boundary is provided as a list of vertices and a list of facets. Each facet is specified as an integer array containing the arrays vertices indices in the vertices list. Each facet normal is oriented by right hand rule to the facet vertices list.
Some basic sanity checks are performed but not everything is thoroughly assessed, so it remains under caller responsibility to ensure the vertices and facets are consistent and properly define a polyhedrons set.

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).
