I have a working project using OCCT-7.5.0 and Qt-5.15.2, I am using QQuickFramebufferObject to visualize OCCT inside Qml. There are many changes in graphic stack in Qt6, but in theory, it is still possible to use OpenGL, I have updated the dependencies and i have set GraphicsApi to OpenQL, but the framebufferobject is plain white. It receives events and render is called on Renderer instance, but the screen is just white. All other Qml Items work as expected except the OCCT FBO.
Do anyone have attempted this with some success?
With deprecation of OpenGL everywhere, i am afraid my OCCT app will be in trouble in near future. I have not tried VTK, but it seems that VTK is an option. Does anyone know about some minimal working example of VTK+Qt+OCCT?
