◆ createPolyhedron()

G4int HepPolyhedron::createPolyhedron ( G4int  Nnodes,
G4int  Nfaces,
const G4double  xyz[][3],
const G4int  faces[][4] 
)

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
Nnodesnumber of nodes
Nfacesnumber of faces
xyznodes
facesfaces (quadrilaterals or triangles)
Returns
status of the operation - is non-zero in case of problem
