Integration 3D Interactive presentation widget problem

[Anes]

Hello,
I am working on software to develop control and data acquisition systems (SCADA) called WinCC OA.
this latter does not give the possibility to import 3d objects and animated objects, but it does give the possibility to create API.

For my case it is an EWO (External Widget Object), you will find attached the template I generated, it is developed in C++ using the Qt platform.

honestly to develop an interactive 3d simulator purely in Qt respecting the generated template I can't even get started.

here is a video to give an idea about the 3d simulator I want to make
https://www.youtube.com/watch?v=yu-M6Omk1ps

I thought about developing the simulator using a 3d engine , I start to develop it using unity (3d metro station visualization where I control camera position from buttons, I can make on/off the elevator ...etc).

I managed to do but my problem is the integration, how to integrate this simulator into WinCC OA, i.e. the presentation I made under unity will be a widget in the new software, and I can control elevator, escalators .. etc from this last software.

Help please

Best Regards

Anes
