Mixing 2D and 3D

[August Lammersdorf, InteractiveMesh]

 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:
