Double_t Safety(Double_t *point, Bool_t)


 Compute safety distance for a union node;



void SavePrimitive(ostream &out, Option_t *option /*= ""*/)


 Save a primitive as a C++ statement(s) on output stream "out".



void Sizeof3D()


 Register 3D size of this shape.



Int_t DistanceToPrimitive(Int_t px, Int_t py)
