Jan 29, 2020 · I am using MacOS 10.15.2 and Geant4.10.06 I have been able to configure and build Geant4 with Qt after some struggle. Now my problem is OpenGL opens as it did before without the Qt GUI. I have listed my step by step process for building Geant4 with Qt.

Jul 12, 2021 · As a workaround try GEANT4_USE_QT=OFF and GEANT4_USE_OPENGL_X11=ON and rebuild (make clean, then cmake and make).

This tutorial is designed for anyone who wants to learn OpenGL Visualization for Geant4 with Qt powerfull toolkit. This tutorial can be used on its own, but gives the most comprehensive introduction to Geant4 visualization when used as part of the following full set of documents: Geant4 Installation Guides

While some Geant4 visualization drivers are always included by default in your Geant4 build (because they require no external libraries), OpenGL is not included by default. You must explicitly add OpenGL to your build by setting an environment variable and then remaking.

Oct 17, 2021 · I successfully compiled Geant4 with CMake using the options -DGEANT4_USE_OPENGL_WIN32=ON -DGEANT4_USE_QT=ON and I linked QT dirs in the CMake. The compilation goes well and I can compile and execute exampleB1.

Introduction to Geant4 Visualization 10 OpenGL with Qt Control ! New visualization driver and user interface ! requires that you install Qt and link against this in your Geant4 ./Configure ! you can customize the interface to control any Geant4 command Supported by Laurent Garnier

Geant4’s visualization system is modular. By creating just three new classes, you can direct Geant4 information to your own visualization system. Most examples come with a visualization macro more complete (including our exercise), which will be explained in more details later.

If you build Geant4 using the standard CMake procedure, you include Qt by setting GEANT4_USE_QT to ON. In order to use the the Qt driver, you need the OpenGL library, which is installed in many platforms by default and CMake will find it.

Some of these graphics systems use a graphics library compiled with Geant4, such as OpenGL, Qt, while others involve a separate application, such as HepRApp or DAWN. Most examples include a vis.mac to perform typical visualization for that example.
