How to get faces of TGeoSomething?

ROOT

I write:

TGeoVolume *ggg = geom->MakeSomething( …)
TGeoSomething *smth=ggg->GetShape();

double vert[10000];
smth->SetPoints(vert);

So the question is - how to find not only points of shape but its faces also? (in wich sequence the points should be connected?)

Hi,

You have too look in TGeoPainter::PaintWhatever to see how points are connected and how segments make faces for each specific shape.

what about Pgon? there is no PaintPgon method.

Pgon is paint exactly like a Pcon, just the number of segments is different - look at PaintPcon()
