I think there is a bug for G4BREPSolid/G4ToroidalSurface::Intersect. The code original code are :
G4double rnorm = MaxRadius - MinRadius; // ei tietoa onko oikein... rho = MinRadius*MinRadius / (rnorm*rnorm);
But according to the book Graphic GEMS II (by James Arvo) , considering a and b is the two small radius of the Elliptical torus, we have
rho = (a*a)/(b*b)
For circular torus, a = b, therefore rho should be 1.0 in the code.
Am I correct?
