摘要： A method for managing a display space for a 3D environment is provided. A 3D scene having at least one scene object is displayed and the visible surfaces of the scene objects are represented as visible space in a 2D view plane representation. Controllable objects that are to be placed in the scene are defined by parameters such as size, placement priority, proximity relationships and the like. The available space for placing controllable objects, which can include empty space and low priority background and foreground regions, is determined for each controllable object. The placement for controllable objects in the 3D space is then determined in accordance with at least placement parameter and one of the visible space and available space of the view-plane representation such that view management objectives, such as not occluding important scene objects, are accomplished.

摘要： Color coded signals are superimposed upon one another in order to more conveniently understand phenomenon to which the signals relate. A specific application of the technique is non-destructive eddy-current testing of tubes used in devises such as nuclear reactors for detecting anomalies such as pits, through-holes and dents. The signals generated during the eddy tests are displayed as overlapping lissajous transforms which produce distinctive color patterns for each anomaly.

摘要： A method and system for implementing a screen saver function is described. A peak value of a characteristic such as beam current magnitude of a video signal being processed is determined. An average value of the same characteristic of the video signal is also determined. Changes in this average value is additionally monitored. Therefore, the characteristic of the video signal is adjusted only if the peak value exceeds a first threshold and a change less than a second threshold is detected in the average value.

摘要： The preferred embodiment a stereoscopic LCD shutter glass driver system requires only a total of 3 CMOS integrated circuit chips in order to convert horizontal and vertical sync signals into LCD shutter glass drive signals. A negative charge pump is used increase the LCD drive voltage thereby reducing 3D crosstalk in the image. The video signal input is shown with a passthrough connection intended for direct hook-up to a television or CRT monitor. A first flip flop detects vertical and horizontal sync and is used to drive the charge pump. A stable, predictable field ID signal is produced by the flip flop whose two complimentary outputs act as inputs to a second flip flop chip which produces the drive signals for the LCD shutter glasses. A third flip flop produces a LCD “common” signal that is sent to both LCD shutters. The second flip flop produces a drive signal for each LCD shutter. A field swap between the two shutters is implemented with a switch located at the output of the third flip flop.

摘要： A graphics accelerator responds to commands from a computer in a graphic system by storing the definitions of nonuniform rational B-spline patches and their associated triming curves. The graphics accelerator then produces device coordinates for trimmed polygons computed for each patch and sends these polygons to a display. Various improvements are incorporated to minimize the effects of roundoff error. The B-spline definitions of the trimming curves in the uv parameter space of each patch are converted to approximating short straight line segments. Untrimmed polygon vertices, the end points of the straight line segments and the intersections of the straight line segments with subspan boundaries corresponding to polygon edges are kept in a data structure of linked lists of vertex tables. The data structure is traversed to determine new polygon vertices for trimmed polygons. The trimming mechanism is compatible with recursive subdivision of patches to overcome pratical limitations on the number of trimming curves that may be associated with each patch. The length of the straight line segments of the trimming curves is adjusted to compensate for less than ideal parameterization of the trimming curve functions. Associated with each trimming curve within a patch is information about the position of that trimming curve in the span. As each polygon for that patch is generated, those trimming curves that are clearly outside the clip limits for that polygon are excluded from consideration. This reduces the average number of trimming curves that must be processed for the patch, and increases the speed of the graphics accelerator.

摘要： A display system having a screen and two spaced projectors arranged to illuminate respective parts of the screen. The screen includes a diffusor which serves to scatter light incident on the screen at a particular point in a manner such that more of the light is propagated, after scattering, more in a given direction of maximum intensity than in any other given direction. The screen has a refractor which serves to deflect the light before or after scattering from adjacent points of the different parts so as to reduce or eliminate an angle between the directions of maximum intensity for these adjacent points.

摘要： A system for presenting a head-up display to the operator of a vehicle is disclosed. This system comprises a light source fiber optic bundle (52) which is secured to the helmet of the vehicle operator and generates a light beam signal which travels at an angle proportional to the orientation of the pilot's head and, accordingly, his line-of-sight. This beam is detected by a detector (68) which is optically coupled to the light beam and provides line-of-sight information at its ouput. A computer (96) receives the line-of-sight information together with other information and sends it via a cathode ray tube (112) and an optical coupler (14) to a beamsplitter (16) which provides that information to the operator of the vehicle while allowing the operator to see through the beamsplitter (16), thus providing the operator with additional information without obstructing his view.

摘要： The graphic generator includes a coding section which produces a series of data words which describe the input data to be displayed in terms of change of slope over time. Each data word contains enough information to describe one line on a display raster. The data is displayed as a three variable image, one variable being in the horizontal dimension of the raster, another variable being in the vertical dimension of the raster, the other variable being the intensity information of the display, which is superimposed on the vertical axis of the display through a summation of the vertical deflection circuit. The lines of the raster may be rotated with the superimposed intensity information being held constant as a reference, so that the view of the image appears to change, thus providing a three dimensional view of the image. On successive raster drawing cycles, as each line is drawn, the data word for that line is compared with the data word for the last previous line, and then further previous lines, on a bit by bit basis. If the data word bit for the line being drawn is the smaller, it is then blanked on the next drawing cycle to solve the hidden line problem.
