摘要： An interactive computer simulation system includes one or more processors for performing an interactive computer simulation in an interactive simulated environment based on user input and for generating images related to the interactive computer simulation. The system includes a dome for displaying the images, the dome being cut by a base below an equatorial plane of the dome, the images being displayed on the dome at a general-projection distance. The system further includes an adjusted-projection panel having an adjusted-projection surface defining an adjusted-projection distance smaller than the general-projection distance for addressing a vergence-accommodation conflict when simulated ground images are displayed.

摘要： A simulator is disclosed. A cockpit model comprising a plurality of cockpit model parts that collectively correspond to a simulated cockpit in a simulated vehicle is maintained. For each frame of a plurality of frames, a plurality of cockpit view frustums are determined, each cockpit view frustum corresponding to a different cockpit view of a plurality of cockpit views of the simulated cockpit. Shared cockpit scene information comprising a set of cockpit model parts that are within any of the plurality of cockpit views is generated based on the plurality of cockpit view frustums. A processing device submits to a graphics processing unit (GPU) the shared cockpit scene information and GPU instructions that direct the GPU to generate a plurality of cockpit view images that correspond to the plurality of cockpit views from the shared cockpit scene information. The GPU generates the plurality of cockpit view images.

摘要： The present image generator visually suppresses a gap between two adjacent reflective surfaces of a reflective display. The image generator comprises memory and a processor. The memory stores position of the gap on the reflective display. The processor analyzes a stream of images to be displayed on the reflective display and determines corresponding lighting data alongside the gap. The processor further controls at least one lighting unit located behind a seam inserted in the gap based on the determined lighting data.

摘要： A video display is provided which includes a display screen mounted to a forward end of the video display, a video projector having a center of gravity, and a reflective assembly for directing light from within the video projector to the display screen. The video display further includes a frame for supporting the display screen, the video projector and a reflective assembly in an operative relationship. Stationary brackets are rigidly mounted to the frame, and projector brackets are rigidly mounted to the video projector. The projector brackets are pivotally mounted to the stationary brackets for rotating relative to the stationary brackets, about a pivot point. Rotating the projector brackets relative to the stationary brackets rotates the video projector relative to the frame, from a first position to a second position. When the video projector is rotated about the frame from the first position to the second position, the center of gravity of the video projector is moved from forward of the pivot point to rearward of the pivot point and a rearward end of the video projector is moved in a downward direction. The weight of the video projector is supported when it is disposed in the second position so that it will automatically remain in the second position for servicing.

摘要： A visual display system, such as a flight simulation system, includes a number of display screens and a number of associated video projectors which project predetermined video images on the display screens in response to control signals provided by an operator. In one embodiment, the display screens are circumscribed by an imaginary sphere having a predetermined radius and centered about the design eye of the visual display system. The design eye is generally positioned in a predetermined fixed relation to the operator such that the distortion of the displayed video image is reduced. In another embodiment, the video projectors are mounted in a linear side-by-side relationship on a rear side of the display screens, thereby reducing the overall size of the visual display system. The visual display system also includes image redirection means, such as fold mirrors, to redirect the video images projected by the aligned video projectors so as to provide the video images to the respective display screens in a direction perpendicular to the planar surface of each display screen. In addition, adjacent display screens can be attached by a pair of rearwardly extending tabs which are positioned so as to not mask the projected video images. At least one of the pair of tabs is opaque such that the projected video images will not pass between the adjacent display screens. Thus, at least the portion of the video image displayed along the edges of the adjacent display screens is clarified.

摘要： A display system employs rear projection to a curved, translucent display or image screen. A lens between the projecting device and the display screen eliminates or reduces distortion by altering a convergence of the projected image, transforming the projected image from diverging to converging for a convex rear projection screen surface or further diverging the image for a concave rear projection screen surface. A lightweight and economical Fresnel lens may be employed for this purpose.

摘要： A compact display system simulates a panoramic view to an observer located at a central viewing station. A toric mirror, comprising a compressed portion of a sphere, has a concave reflective surface disposed in surrounding relation to the given viewing station while a spherical rear projection screen which receives projected image light on its inner surface presents a panoramic image to the toric mirror from its outer surface. A plurality of projectors are disposed tangentially above the upper periphery of the rear projection screen and project associated portions of the light image onto the inside of the screen via fold mirrors. Each projector includes a high intensity CRT and a color shutter.

摘要： A method and apparatus for displaying an image that is subject to multiple distortions substantially without distortion is provided. The image is recorded from a first viewpoint and subject to a first distortion and played back from a second viewpoint and subject to a second distortion. The display surface may also be distorted (e.g., curved). By mapping back through the projector to the screen and through the camera (at the viewpoint), the image is transformed so that it can be viewed from the viewpoint with little or no distortion.

摘要： In an area of interest (AOI) display, a detailed image is projected on a screen at the area of interest while a background image is projected on the surrounding area such that the boarder between the two areas varies in an orbital oscillating pattern to accomplish visual blending. A combiner includes a transparent portion to accommodate projection of the background image at the area of interest. The opaque portion carries a mirror to reflect the detailed image filling the area of interest. The combiner is oscillated in an orbital pattern at a resonant frequency, e.g. 210 Hertz by a three phase electromechanical drive unit.
