Dynamic Arrangement of Elements in Three-Dimensional Space
In one embodiment, a method includes determining one or more three-dimensional (3D) objects defined in 3D space for display. The one or more 3D objects may be projected into corresponding one or more two-dimensional (2D) objects defined in 2D space. Run-time layout characteristics of the one or more 2D objects may be defined using a layout module. The run-time layout characteristics defined by the layout module may be send to a 3D rendering engine. The 3D rendering engine may render a display containing the one or more 3D objects using the run-time layout characteristics of the one or more 2D objects defined by the layout module.

defining run-time layout characteristics of the one or more 2D objects using a layout module;
sending, to a 3D rendering engine, the run-time layout characteristics defined by the layout module; and

5 . The method of claim 4 , wherein rendering the display containing the one or more 3D objects comprises:
transforming the projected one or more 2D objects back to the corresponding one or more 3D objects; and
placing the one or more 3D objects in the display region using the placement information indicated by the layout module.
