Bool_t TGLH2PolyPainter::InitGeometry ( )

virtual

All pointers are validated here (and in functions called from here). If any pointer is invalid - zero, or has unexpected type (dynamic_cast fails) - InitGeometry will return false and nothing will be painted later. That's why there are no checks in other functions.
