Abstract: A three-dimensional stereoscopic image display system comprising an observer position guide configured to guide an observer wearing stereoscopic three-dimensional glasses to a position to perceive a three-dimensional image based on the position of the observer position guide.

Abstract: A display assembly includes: a scene display screen; a privacy screen mounted over the scene display screen; a first mirror having a reflection side (“the first reflection side”) and a transmission side (“the first transmission side”). The first reflection side is mounted at an angle to the scene display screen for illumination; a background display screen faces the first transmission side for illumination thereof; and a housing arranged about the scene display screen, background display screen and first mirror for reducing ambient light within the housing including an opening for viewing of the reflection side of the first mirror therethrough. An image generation assembly is coupled to the scene display screen for producing a moving scene image thereon. The observer views the background display screen and the scene display screen simultaneously when viewing the reflection side of the first mirror and the privacy screen prevents viewing a secondary scene image.

Abstract: A virtual reality imaging system for two or more users including: at least one screen for presenting images of a virtual environment to two or more users; an imaging assembly, including two or more sets of projectors corresponding to the two or more users for producing images on the at least one screen; a tracking system that is configured to track each of the two or more users; a computer that is programmed to produce stereo 3D images of the virtual environment corresponding to tracking data from the tracking system for phone providing different views of the same virtual environment; stereo 3D glasses arranged to provide stereo 3D images; and an image separation arrangement whereby each user sees images emanating from a corresponding one of the sets of projectors only.

Abstract: A method is provided for rendering a three dimensional scene upon an electronic processor based system such as a computer, cellular phone, games console or other device. The method involves rendering a three dimensional scene by activating pixels of an electronic display device using a perspective projection for some portions of the scene and an orthogonal projection for others. A far less computationally expensive orthogonal projection is used for rendering other portions of the scene which meet a predetermined condition. The method results in a rendered scene displayed by pixels of the display device that appears overall to have been realistically rendered using a perspective transformation. However, since portions of the rendered scene have been rendered using an orthogonal projection, the method is computationally less expensive than rendering using only perspective projection.

Abstract: A computer graphics method is provided for implementation upon an electronic processor based system such as a computer, cellular phone, games console or other device. The method involves rendering a three dimensional scene i.e. by activating pixels of an electronic display device of the system, using a perspective projection for some portions of the scene and an orthogonal projection for others. Perspective projection is used in respect of those portions of the scene for which a noticeable difference would occur between rendering in perspective projection and rendering with an orthogonal projection. A far less computationally expensive orthogonal projection is used for rendering other portions of the scene which meet a predetermined condition. The method results in a rendered scene displayed by pixels of the display device that appears overall to have been realistically rendered using a perspective transformation.
