1. A method for presenting a three dimensional (3D) scene using a display device, comprising:

  • determining a first perspective of a user, wherein determining the first perspective comprises;

    determining, via a tracking system coupled to the display, a first viewpoint of the user, including determining, by a processor of the display device and based on information from the tracking system, a position and orientation of the first viewpoint relative to a position and orientation of a surface of the display;

    displaying a first 3D image on the display based on the first perspective of the user, wherein said displaying the first 3D image comprises displaying the 3D scene according to a first projection;

    rendering, by the processor, the first projection based on a render surface, wherein the surface of the display has a first correlation to the first viewpoint in physical space, wherein the render surface has a second correlation to the first viewpoint in virtual space, and wherein the first correlation and second correlation are equivalent;

    determining, via the tracking system, a second perspective of the user; and

    displaying a second 3D image on the display based on the second perspective of the user, wherein said displaying the second 3D image comprises displaying an updated 3D scene according to a second projection;

    wherein the second perspective is different from the first perspective, wherein the first perspective is a first oblique perspective and wherein the second perspective is a second oblique perspective.
