Vidio games usually draw the player's 2D UI elements in a second step
on top of the perspective 3D scene in the parallel/orthographic
projection mode (overlay or head-up display - HUD).
This approach is already widest supported by JavaFX even with
perspective 3D transforms. Using a StackPane or a self-written layered
pane the user interface can be rendered onto the 3D SubScene and can be
designed, updated and animated with:
- layout panes : javafx.scene.layout.*
- UI controls : subclasses of javafx.scene.control.*
- two-dimensional shapes : javafx.scene.effect.shape*
- graphical effects : javafx.scene.effect.*
- images : javafx.scene.image.*
- shapes and background filler : javafx.scene.paint.*
- transformations : javafx.scene.transform
- animations : javafx.animation
Is there any other 3D API or game engine based on C++ or Java which can
beat this scenario?
FXTuxCube is a simple JavaFX 3D example with 2D elements drawn on top
of a 3D SubScene:

In my field of work (avionics displays),we might have a lot of use
cases for that. However, you also have that in video games, where
they
like to render 2D interactive panels in a 3D perspective in the game
world.
