Three-dimensional displays and related techniques

A device for generating a stereoscopic 3D image of a casino game apparatus, the device comprising:

• at least one processor;
• and
• at least one processor-readable storage medium storing processor-executable instructions that, when executed by the at least one processor, cause the at least one processor to perform acts comprising:
• accessing, from a storage medium, a first static 2D image of the casino game apparatus from a first viewpoint, and a second static 2D image of the casino game apparatus from a second viewpoint,
• applying the first static 2D image to a surface of a 3D object that is defined in a virtual 3D environment as a first texture of the surface in a first view of the virtual 3D environment,
• applying the second static 2D image to the surface of the 3D object that is defined in the virtual 3D environment as a second texture of the surface in a second view of the virtual 3D environment,
• generating a stereoscopic 3D image of the casino game apparatus, the stereoscopic 3D image comprising the first view of the virtual 3D environment with the first static 2D image applied as the first texture to the surface and the second view of the virtual 3D environment with the second static 2D image applied as the second texture to the surface;
• and
• composing the first view of the virtual 3D environment by:
• accessing an image of the casino game apparatus in which a light source is active and an image of the casino game apparatus in which the light source is inactive;
• subtracting pixel data of the image in which the light source is inactive from pixel data of the image in which the light source is active to generate a differential image comprising differential illumination information associated with the light source;
• and
• adding the differential illumination information to the first view of the virtual 3D environment to compose the first view of the virtual 3D environment in which the light source is active.

At least one processor-readable storage medium encoded with processor-executable instructions that, when executed, cause a processor to perform acts for generating a stereoscopic 3D image of a casino game apparatus, the acts comprising:

• accessing, from a storage medium, a first static 2D image of the casino game apparatus from a first viewpoint, and a second static 2D image of the casino game apparatus from a second viewpoint;
• applying the first static 2D image to a surface of a 3D object that is defined in a virtual 3D environment as a first texture of the surface in a first view of the virtual 3D environment;
• applying the second static 2D image to the surface of the 3D object that is defined in the virtual 3D environment as a second texture of the surface in a second view of the virtual 3D environment;
• and
• generating a stereoscopic 3D image of the casino game apparatus, the stereoscopic 3D image comprising the first view of the virtual 3D environment with the first static 2D image applied as the first texture to the surface and the second view of the virtual 3D environment with the second static 2D image applied as the second texture to the surface,
• wherein the first and/or the second static 2D image is derived from a time-varying video of the casino game apparatus, and
• wherein the first view of the virtual 3D environment is generated by:
• accessing an image of the casino game apparatus in which a light source is active and an image of the casino game apparatus in which the light source is inactive;
• subtracting pixel data of the image in which the light source is inactive from pixel data of the image in which the light source is active to generate a differential image comprising differential illumination information associated with the light source;
• and
• adding the differential illumination information to the first view of the virtual 3D environment to compose the first view of the virtual 3D environment in which the light source is active.

A method of generating a stereoscopic 3D visual image depicting a physical casino game apparatus with improved fidelity, by applying multiple static 2D images of the physical casino game apparatus as surface textures to a surface in a virtual 3D environment to form an integrated stereoscopic 3D visual stimulus, the method comprising:

• accessing, from a storage medium, a first static 2D image of the physical casino game apparatus taken from a first viewpoint, and a second static 2D image of the physical casino game apparatus taken from a second viewpoint;
• and
• executing stored instructions via at least one processor to:
• apply the first static 2D image to a surface of a 3D object that is defined in a virtual 3D environment as a first texture of the surface in a first view of the virtual 3D environment;
• apply the second static 2D image to the surface of the 3D object that is defined in the virtual 3D environment as a second texture of the surface in a second view of the virtual 3D environment;
