26 /// \brief The brush primitive.
28 /// A collection of planes that define a convex polyhedron.
29 /// The Boundary-Representation of this primitive is a manifold polygonal mesh.
30 /// Each face polygon is represented by a list of vertices in a \c Winding.
31 /// Each vertex is associated with another face that is adjacent to the edge
32 /// formed by itself and the next vertex in the winding. This information can
33 /// be used to find edge-pairs and vertex-rings.
