Virtual environment rendering

A system for rendering a virtual environment includes a hardware processor, a memory, and a simulation generator software code stored in the memory. The hardware processor is configured to execute the simulation generator software code to receive a three-dimensional-representation (3D-representation) of a physical object, and to receive a two-dimensional-image (2D-image) of the physical object. The hardware processor is also configured to execute the simulation generator software code to compose a simulation of the virtual environment using the 3D-representation and the 2D-image, in which the 3D-representation of the physical object is situated between the 2D-image of the physical object and a predetermined viewpoint of the virtual environment. The hardware processor further executes the simulation generator software code to render the virtual environment such that the 2D-image of the physical object, but not the 3D-representation of the physical object, is visibly rendered.
