-------------------------------------------------------------------------------

## 2024-03-13 Gabriele Cosmo (visQt3D-V11-01-08)
- Fixed compilation error on Windows for ambiguous string assignment in
  G4Qt3DSceneHandler::CreateNewNode().

## 2023-10-14 John Allison (visQt3D-V11-01-07)
- G4Qt3DSceneHandler.cc: Add dummy normal line attributes - Qt6 seems to require!!
  - I am puzzled - why do lines need normals?
  - Fixes wireframe drawing.
  - Does not seem to fix trajectory line drawing, which is curious.

## 2023-10-07 John Allison (visQt3D-V11-01-06)
- G4Qt3DSceneHandler.cc:
  - Establish the top physical volume Qt3D entities from the scene.
    - This is a better way than using transportation worlds.
      - In some circumstances, such as the standalone examples,
        G4TransportationManager is no longer instantiated in time,
        causing a crash. But this way is better anyway.

## 2023-08-14 John Allison (visQt3D-V11-01-05)
- G4Qt3D:
  - Simplify IsUISessionCompatible.
    - Exploit new method, G4UImanager::GetBaseSession (intercoms-V11-01-07).

## 2023-07-01 John Allison (visQt3D-V11-01-04)
- Fix precision-loss warning

## 2023-04-26 Ben Morgan (visQt3D-V11-01-03)
- Support compilation against Qt5 and Qt6.

## 2023-03-22 Ben Morgan (visQt3D-V11-01-02)
- Export public compile definitions to indicate availablity of specific drivers. Moves to
  "use on link" model.

## 2023-02-06 Ben Morgan (visQt3D-V11-01-01)
- Isolate private headers and update dependencies

## 2023-01-30 Ben Morgan (visQt3D-V11-01-00)
- Link to new G4UIcore/UIimplementation modules in place of former G4UIbasic/UIcommon

## 2022-11-25 Gabriele Cosmo (visQt3D-V11-00-12)
- Fixed compilation warning for implicit type conversions on macOS/XCode 14.1.

## 2022-11-06 John Allison (visQt3D-V11-00-11)
- Eliminate G4cerr and introduce G4warn.
  - `#define G4warn G4cout`
    - The above is temporary until a genuine G4warn output stream is
      implemented.
  - Change G4cerr to G4warn in all cases.
  - Change G4cout to G4warn in those cases where it is clearly
    an error report or a warning.

## 2022-10-28 John Allison (visQt3D-V11-00-10)
- Request kernel visit when cutaway mode changes:
  - G4Qt3DViewer.cc

## 2022-09-14 John Allison (visQt3D-V11-00-09)
- G4Qt3DViewer.cc:
  - Add check on special mesh rendering option in CompareForKernelVisit.

## 2022-09-03 Ben Morgan (visQt3D-V11-00-08)
- Remove unused header from G4heprandom to resolve consistency test

## 2022-04-06 John Allison (visQt3D-V11-00-07)
- Fix compiler warnings:
  - G4Qt3DSceneHandler.hh: Add `using G4VSceneHandler::AddCompound` to
    avoid warnings.
  - G4Qt3DSceneHandler.cc: Change `world` to `wrld` to avoid warnings.
    - `world` shadows an `enum` in `G4VSceneHandler`. Maybe a better solution
       is to encapsulate the enum.

## 2022-05-03 Ben Morgan (visQt3D-V11-00-06)
- Preliminary build support for Qt5 and Qt6

## 2022-04-06 John Allison (visQt3D-V11-00-05)
- `G4Qt3DSceneHandler`:
  - `void G4Qt3DSceneHandler::AddPrimitive (const G4Polymarker& polymarker)`:
    - Update to current usage.
  - `void G4Qt3DSceneHandler::AddPrimitive(const G4Polyhedron& polyhedron)`:
    - Comment out common line elimination - too expensive for a large
      polyhedron.
    - Maybe eliminate altogether in future?.
    - Allow the graphics-reps utilities to optimise things like this.
  - Use StandardSpecialMeshRendering(mesh).
    - Of course, only if special mesh rendering is requested.

## 2022-03-05 John Allison (visQt3D-V11-00-04)
- G4Qt3DSceneHandler::AddCompound(const G4Mesh& mesh):
  - For parameterised tetrahedron mesh, call default
    G4VSceneHandler::DrawTetMeshAsDots(mesh).
  - Tested on "ICRP145", a Geant4 application that we hope can become
    a Geant4 advanced example, downloaded from the supplementary material
    of Kim et al, ICRP, 2020. Adult mesh-type reference computational phantoms,
    ICRP Publication 145, Ann. ICRP 49(3).

## 2022-01-28 Ben Morgan (visQt3D-V11-00-03)
- Replace `geant4_global_library_target` with direct file inclusion and
  call to `geant4_add_category` to define library build from source modules.

## 2022-01-16 John Allison (visQt3D-V11-00-02)
- G4Qt3DViewer::wheelEvent:
  - Re-program wheelEvent for perspective projection:
    - Takes into account the extent of the scene.

## 2021-12-16 John Allison (visQt3D-V11-00-01)
- G4Qt3DSceneHandler.cc:
  - AddCompound(const G4Mesh& mesh):
    - Use base class utility G4VSceneHandler::Draw3DRectMeshAsDots(mesh);

## 2021-12-10 Ben Morgan (visQt3D-V11-00-00)
- Change to new Markdown History format
