摘要： A Digital Elevation Database is converted to a Polygon Database by creating square cells of varying sizes, starting with a minimum size cell. A center elevation point in the cell is used to form four three-dimensional triangles. The points within the cell are then tested against the flatness criteria. If the cell meets the flatness criteria it is expanded and tested again. This goes on until the cell fails the flatness criteria or a maximum specified cell size is reached. The cell parameters for the last trial cell meeting the flatness criteria or the maximum specified cell size are then entered into the polygon database. The points in the cell are then removed from the elevation database and the process starts over until all the points have been processed. In a second embodiment the procedure starts with a maximum size cell and the cell size is reduced until the cell meets the flatness criteria.

摘要： A Z-Buffer is added to a Row Addressable Graphics Memory With Flash Fill so that a Z (or Depth) value is supplied with each Start and End address. The Z value is calculated for each pixel between the Start and End address. This value is compared to the existing Z value for that pixel stored in the Z-Buffer. Values less than the existing value replace the Z value for that pixel in the Z-Buffer and allow the new pixel to be written into the display memory. The Z data are read, modified, and written back to the Z-Buffer in parallel thereby requiring a maximum of three memory cycles to operate on a line segment independent of the length of the line.
摘要翻译：将Z缓冲区添加到具有闪存填充的行可寻址图形存储器中，以便每个起始和结束地址都提供Z（或深度）值。为开始和结束地址之间的每个像素计算Z值。该值与存储在Z缓冲区中的像素的现有Z值进行比较。小于现有值的值替换Z缓冲区中该像素的Z值，并允许将新像素写入显示存储器。 Z数据被并行地读取，修改和写回到Z缓冲器中，因此需要最多三个存储器周期来在线段上独立于线路长度进行操作。

摘要： A pilot aid using synthetic reality consists of a way to determine the aircraft's position and attitude such as by the global positioning system (GPS), a digital data base containing three-dimensional polygon data for terrain and manmade structures, a computer, and a display. The computer uses the aircraft's position and attitude to look up the terrain and manmade structure data in the data base and by using standard computer graphics methods creates a projected three-dimensional scene on a cockpit display. This presents the pilot with a synthesized view of the world regardless of the actual visibility. A second embodiment uses a head-mounted display with a head position sensor to provide the pilot with a synthesized view of the world that responds to where he or she is looking and which is not blocked by the cockpit or other aircraft structures. A third embodiment allows the pilot to preview the route ahead or to replay previous flights.

摘要： A digital map system for displaying three dimensional terrain data uses terrain data in the form of polygons. The polygon database is produced from a database of elevation points which are divided into, for example, n.times.n (where n is a positive integer) squares which have an elevation point in the center of the square. The center point forms four polygons with the corners of the square. The elevation of the center point may be chosen to be the highest elevation point in the n.times.n square, the average elevation of the elevation points in the n.times.n square, the elevation of the actual center point, or other methods. The method chosen depends on how the data base is to be used. The size of the n.times.n square chosen also depends on how the data base is to be used since there is a tradeoff between the resolution of the displayed scene and the amount of data reduction from the original database of elevation points. The polygon database may be used in a pilot aid using a synthetic environment, a flight simulator, as part of the control system for a remotely piloted vehicle, or in a video game.
摘要翻译：用于显示三维地形数据的数字地图系统以多边形的形式使用地形数据。多边形数据库是从高程点的数据库生成的，该数据库被划分为例如在正方形中心具有高程点的nxn（其中n是正整数）正方形。中心点形成与方形角的四个多边形。中心点的高程可以选择为nxn平方的最高高度点，nxn平方的高程平均仰角，实际中心点的高程，或其他方法。所选择的方法取决于如何使用数据库。所选择的nxn平方的大小还取决于如何使用数据库，因为在显示场景的分辨率与原始数据库的高程点之间的数据减少量之间存在权衡。多边形数据库可以用于使用合成环境的飞行员辅助，飞行模拟器，作为远程驾驶车辆的控制系统的一部分，或在视频游戏中。

摘要： A realistic illusion of listening to an actual AM radio is produced by providing a number of audio program signals and by simulating the process of tuning across the radio dial where each station is playing a different program. In a superheterodyne receiver using envelope detection, tuning a station off-channel results in a changing mixture of distortion and noise. The distortion function is caused by a variety of processes, among them being the filtering action as parts of the signal spectrum are cut off by the bandpass filter in the IF amplifier. Another is caused by the reduction in the carrier which causes the foldover of negative peaks in the envelope detector.

摘要： A method and apparatus that allows a remote aircraft to be controlled by a remotely located pilot who is presented with a synthesized three-dimensional projected view representing the environment around the remote aircraft. According to one aspect of the invention, a remote aircraft transmits its three-dimensional position and orientation to a remote pilot station. The remote pilot station applies this information to a digital database containing a three dimensional description of the environment around the remote aircraft to present the remote pilot with a three dimensional projected view of this environment. The remote pilot reacts to this view and interacts with the pilot controls, whose signals are transmitted back to the remote aircraft. In addition, the system compensates for the communications delay between the remote aircraft and the remote pilot station by controlling the sensitivity of the pilot controls.
