Qt 3D vs Qt Quick 3D

Magres

I'm about to implement some 3D project for simulating and have to decide to use Qt 3D or Qt Quick 3D. The latter promises better performance but not about to replace the Qt 3D. Both branches seem to be developed actively. Could somone give any guidelines, pros, cons? Thanks in advance.

Do you want to write QML or C++?

Both are exposing a QML interface.

Qt Quick 3D is available under the commercial license from The Qt Company. In addition, it is available under the GNU General Public License, version 3. See Qt Licensing for further details. Source

So, if you use Qt Quick 3D you must share your code (GPL). But if you use Qt 3D you must not share your code (LGPL).

@8Observer8 thank you. It's actually relevant information I missed.
