Hi,

What kind of scene are you talking about ?

signalK

I would like to create 2 scenes something simple like this:

thanks

Sounds like a job for Qt3D.

signalK

which class of Qt3D ?

SGaist

The scene related classes will likely be what you want to show your instruments..

I search on internet example project Qt (file .pro) showing multi scene like i want.
Which link?

SGaist

That as not much to do with your .pro file. It’s your application that is responsible ton handle multiple scenes.

I found a Qt code snippet related to my simple problem:

scene1 -> addItem (theQGraphicsItem);
scene2 -> addItem (theQGraphicsItem);

I then understood that it is necessary to use different pointers scene1 and scene2.
My question:
what kind of pointers are these?
they are declared in which function, in which class?

NB: the moderators are not very explicit!

Before dimming your problem simple, you might want to consider providing a more thorough description of what exactly you want to achieve. Using a framework where you can do 2D/3D rendering with raw OpenGL or more sophisticated high level classes as well as video rendering, asking how to show a 2D/3D scene is not exactly the same as asking how to show two videos showing 2D/3D scenes.

Therefore, can you explain exactly what your application is about and what exactly you are trying to show ?

On a side note, criticising all the moderators when only one of them answered you, trying to help you with the limited information you gave, isn't really a good attitude.
