G4Polyhedron * G4Polyhedra::CreatePolyhedron ( ) const

virtual

Creates user defined polyhedron. This function allows to the user to define arbitrary polyhedron. The faces of the polyhedron should be either triangles or planar quadrilateral. Nodes of a face are defined by indexes pointing to the elements in the xyz array. Numeration of the elements in the array starts from 1 (like in fortran). The indexes can be positive or negative. Negative sign means that the corresponding edge is invisible. The normal of the face should be directed to exterior of the polyhedron.

Parameters

Nnodes	number of nodes
Nfaces	number of faces
xyz	nodes
faces_vec	faces (quadrilaterals or triangles)

Returns: status of the operation - is non-zero in case of problem

Implements G4VCSGfaceted.
