Question Question for G4VSolid::SurfaceNormal() 

Forum: Geometry
Date: 07 May, 2014
From: Yuefeng Qiu <Yuefeng Qiu>

Hello everyone!

I am going to implement a new kind of solid. In order to implement the new class I have some questions about overloading the G4VSolid::SurfaceNormal(const G4ThreeVector& p):

1. whether the point p in always on the surface? I can handle situations that the p is inside the solid or on the surface, but if it is outside the solid then it is a bad new s for me;

2. whether this function is very important? If I offer a approximate solution, how large is the influence?

Thanks in advance!

Best regards,

Yuefeng
