Int_t fNedges number of edges (at least one)
_____________________________________________________________________________
TGeoPgon - a polygone. It has at least 10 parameters :
- the lower phi limit;
- the range in phi;
- the number of edges on each z plane;
- the number of z planes (at least two) where the inner/outer
radii are changing;
- z coordinate, inner and outer radius for each z plane
_____________________________________________________________________________
TGeoPgon(Double_t *param)
Default constructor in GEANT3 style
param[0] = phi1
param[1] = dphi
param[2] = nedges
param[3] = nz
param[4] = z1
param[5] = Rmin1
param[6] = Rmax1
...
TGeoVolume * Divide(TGeoVolume *voldiv, const char *divname, Int_t iaxis, Int_t ndiv, Double_t start, Double_t step)
--- Divide this polygone shape belonging to volume "voldiv" into ndiv volumes
called divname, from start position with the given step. Returns pointer
to created division cell volume in case of Z divisions. Phi divisions are
allowed only if nedges%ndiv=0 and create polygone "segments" with nedges/ndiv edges.
Z divisions can be performed if the divided range is in between two consecutive Z planes.
In case a wrong division axis is supplied, returns pointer to volume that was divided.
Double_t Safety(Double_t *point, Bool_t in)
computes the closest distance from given point to this shape, according
to option. The matching point on the shape is stored in spoint.
