Polygons are defined in the same way as polycones, the difference being just that the segments between consecutive Z planes are regular polygons.

The phi segmentation is preserved and the shape is defined in a similar manner, just that rmin and rmax represent the radii of the circles inscribed in the inner/outer polygon.

The constructor of a polygon has the form:

TGeoPgon(Double_t phi1,Double_t dphi,Int_t nedges,Int_t nz);

TGeoPgon::TGeoPgon

TGeoPgon()

dummy ctor

Definition TGeoPgon.cxx:129

double

int

The extra parameter nedges represent the number of equal edges of the polygons, between phi1 and phi1+dphi.
