摘要： A modular, reconfigurable and easily deployable simulator system includes a plurality of vehicle personality kits and at least one frame to support a single crewstation. Members of a selected kit are coupled to the frame. A multi-platform control system provides on-the-window and in vehicle instrument displays in real-time in response to the crewperson manipulating platform controls. An editor with a graphical user interface provides a capability to modify program segments of the control system thereby altering the behavior of the simulated platform.

摘要： An apparatus for generating an image from data defining a model including a plurality of opaque and translucent features. The image is intended to represent a view of the model from a predetermined eyepoint and is made up from an array of screen space pixels. The image area is divided into an array of sub-areas each of which covers at least one pixel. For each feature in the model that is potentially visible from the eyepoint, a test is conducted to determine which of the sub-areas is at least partially covered by that feature. The position in screen space of at least one sampling point within each sub-area is determined. For each sub-area in turn, and for each sampling point a test is conducted to determine which of the features cover that sampling point. For each feature which covers a sampling point, a function of the distance from the eyepoint to that feature at the sampling point is determined. An output for each pixel within a sub-area is produced, the pixel output corresponding to the combined effects of the sampling point outputs for all sampling points which contribute to that pixel, and the pixel outputs are displayed.

摘要： A weather simulation system that generates and distributes weather data to simulation subsystems for the real time simulation of weather conditions, from three-dimensional real world data. A real world database (11) is accessed to obtain a dataspace of weather data elements, each having a set of various weather-related parameters. For 'out-the-window' weather displays, these data elements are preprocessed (14) to obtain color and transparency values for each data element. The preprocessed data elements are further processed to obtain a prioritized display list of those data elements that are in a field of view. Each data element in this list is assigned a graphics primitive, whose alignment is determined by a wind vector of that data element. Pixel values are assigned to the graphics primitives, using color and transparency values of the associated data elements.

摘要： An apparatus for generating an image to be displayed on a display screen from data defining a model including a plurality of opaque and translucent features. The image is intended to represent a view of the model from a predetermined eyepoint and is made up from an array of screen space pixels to be displayed by a raster scanning process. Each pixel is of uniform colour and intensity, and the pixels together define an image area. The image area is divided into an array of sub-areas each of which covers at least one pixel. For each feature in the model that is potentially visible from the eyepoint, a test is conducted to determine which of the sub-areas is at least partially covered by that feature. A list of feature identifiers is produced in respect of each sub-area, the list for any one sub-area identifying features which at least partially cover that sub-area. The position in screen space of at least one sampling point within each sub-area is determined. For each sub-area in turn, and for each sampling point a test is conducted to determine which of the features in that sub-area's list cover that sampling point. For each feature which covers a sampling point, a function of the distance from the eyepoint to that feature at the sampling point is determined. Feature describing data is stored for each sampling point within a sub-area, the stored data being indicative of at least the distance of the opaque feature which covers the sampling point and is nearest to the eyepoint and the distance and translucency of at least one nearer translucent feature which covers the sampling point. An output is produced for each sampling point within a sub-area, the sampling point output corresponding to the combined effects of the features identified by the stored data. An output for each pixel within a sub-area is produced, the pixel output corresponding to the combined effects of the sampling point outputs for all sampling points which contribute to that pixel, and the pixel outputs are displayed.

摘要： The invention relates generally to a computer controlled digital imaging processing system which operates to compose and construct a sequential stream of scenes for a 2-dimensional display from a library of images of objects such as trees. The invention relates in particular to a method for the real-time true perspective of a pixelized plane object onto a pixelized view screen. The processing speed is sufficient to permit a real-time, or near real-time, analysis of the images by a human operator or a hardware/ software equivalent thereof. The images of objects stored in the library are in the form of rectangular frames. A vehicle such as a helicopter simulator has a field of view which represents what is seen through the "windshield" thereof which in the simulator is the screen of a computer monitor. The four corners of a stored image having a rectangular frame are located by calculations in the face of the monitor screen. The mapping of rows and columns of a stored image is done in two passes or stages. Perspective mapping from the rectangular stored frame to the monitor screen makes conversions on the basis of a different parts of the object being different distances from the "windshield" or face of the monitor screen and thus the more realistic effects of a perspective view are achieved. The two-pass perspective mapping process provides for mapping images of objects which appear in the field of view from the corresponding images in the library to the face of the monitor screen. The method facilitates substantially true perspective mapping as distinguished from approximate perspective mapping.
摘要翻译：本发明一般涉及一种计算机控制的数字成像处理系统，其操作以从诸如树的对象的图像库中构图并构建用于二维显示的顺序的场景流。本发明具体涉及一种将像素化平面物体实时真实透视到像素化视图屏幕上的方法。处理速度足以允许人类操作者或其硬件/软件等效物对图像进行实时或接近实时的分析。存储在库中的对象的图像是矩形框的形式。诸如直升机模拟器的车辆具有表示通过其“挡风玻璃”看到的视野，在模拟器中是计算机监视器的屏幕。通过在监视器屏幕的表面上的计算来定位具有矩形框架的存储图像的四个角。存储图像的行和列的映射在两个遍或多个阶段完成。从矩形存储帧到监视器屏幕的透视映射使得基于对象的不同部分的转换是与“挡风玻璃”或监视器屏幕的面不同的距离，因此实现透视图的更逼真的效果。双向透视映射处理提供了将视野中出现的对象的图像从库中的相应图像映射到监视器屏幕的面部。该方法有助于与近似透视图相区别的基本上真实的透视图。
