Good day! I have found a strange issue with G4Extruded solid. I generated 3,4,5,6-angle prisms (scintillator) with the Radius 7.5mm. The 4,5 -angle prisms demonstrated clearly visible distortion when I generated a VRML scene to check how it looks. Please see the images… I used exact code like yours: const G4int nsect = 3; //3,4,5,6 std::vector<G4TwoVector> polygon(nsect); G4double ang = twopi / nsect; G4double dR = 7.5 * mm.; for (G4int i = 0; i < nsect; ++i) { G4double phi = i * ang; G4do…
