Polyhedra
---------
The tuple of constraints, i.e., equalities and inequalities.
This is semantically equivalent to: ``equalities + inequalities``.
+ .. method:: convex_union(polyhedron[, ...])
+
+ Return the convex union of two or more polyhedra.
+
+ .. method:: asinequalities()
+
+ Express the polyhedron using inequalities, given as a list of expressions greater or equal to 0.
+
.. method:: widen(polyhedron)
Compute the *standard widening* of two polyhedra, à la Halbwachs.
+ In its current implementation, this method is slow and should not be used on large polyhedra.
+
.. data:: Empty
.. method:: cross(vector)
Compute the cross product of two 3D vectors.
- If either one of the vectors is not tridimensional, a :exc:`ValueError` exception is raised.
+ If either one of the vectors is not three-dimensional, a :exc:`ValueError` exception is raised.
.. method:: dot(vector)
