  • G4DAE/G4 triangulation code quickly goes down rabbit hole
  • Idea mesh scanning to identify internal faces
  • ExplodeZVertices makes it obvious that have two closed meshes, not interior faces of one
  • Single face eyeballing
  • Numerical view
  • many upwards going photons think their m1 is Ac when actually Gd
  • Isolate issue to single volume : 3158
    • OpenGL Eyeballing
    • NumPy Look at faces/vertices
  • Next volume : 3159, same structure acting OK
  • Check at detdesc level
