摘要： A high resolution distortion correction system is provided for an arbitrary projection system. First, a field of view is subdivided into multiple viewports. The multiple subdivided viewports provide a first approximation of the distortion. Polygons that are projected onto a particular subdivided viewport are rendered in a frame buffer and stored in texture memory as an intermediate texture image. The intermediate texture images are subsequently applied to a rendered distortion mesh to generate an output image.

摘要： Sensor independent display characterization system spectrally characterizes a display system to measure radiant power emitted by the display system that displays a video image to a trainee pilot during sensor stimulation. A sensor spectral response for each wavelength produced by the stimulated sensor is determined. A stimulated luminance for each color level of the displayed image or for a range of color levels is computed. A color look up table that maps computed stimulated luminance to a set of stimulating color values is generated. When a trainee pilot looks at the displayed image using a sensor having a sensor response that was used in computing the stimulated luminance, the pilot will see an image that was created by simulated spectral rendering. The displayed image is an accurate, display and sensor independent image that the pilot can see during the real flight.

摘要： A wireless networked device incorporating a display, a video camera and a geo-location system receives geo-located data messages from a server system. Messages can be viewed by panning the device, revealing the message's real world location as icons and text overlaid on top of the camera input on the display. The user can reply to the message from her location, add data to an existing message at its original location, send new messages to other users of the system or place a message at a location for other users. World Wide Web geo-located data can be explored using the system's user interface as a browser. The server system uses the physical location of the receiving device to limit messages and data sent to each device according to range and filtering criteria, and can determine line of sight between the device and each actual message to simulate occlusion effects.

摘要： Efficient determination of illumination over large 3D environments, including shadowing, is provided. Illumination, including shadows, is generated using a raster elevation map by a lighting solver. The lighting solver fetches the raster elevation map for an illumination area of interest at the paging rate and produces an illumination map that is applied to terrain and features by a 3D renderer. The lighting solver updates subsets of the illumination map as necessary to reflect changing illumination or movement of the visual area of interest.

摘要： A method and apparatus for rendering lightpoints is provided. For the method of the present invention, a programmer creates a series of texture maps. Each texture map approximates the lobe of a lightpoint at a respective distance from the lightpoint. Each texture map includes transparency texture information. This allows the lightpoint to correctly model fog and other atmospheric conditions. The series of texture maps are encoded in a mipmap associated with the lightpoint. During use, a simulation environment renders the lightpoint using a billboarding technique. The billboarding technique keeps the lobe of the lightpoint oriented towards the eye point. The simulation environment dynamically tracks the distance from the lightpoint to the eye point. Each time the distance changes, the simulation environment selects an appropriate texture map from the mipmap. The appropriate texture map is the texture map that correctly depicts the lightpoint at the distance between the eye point and the lightpoint. In cases where no appropriate texture map exists, the simulation environment generates an interpolated texture map. The simulation environment then applies the selected or generated texture map during rendering of the lightpoint. The result is that the lightpoint is realistically depicted over a wide range of distances.
摘要翻译：提供了一种用于渲染光点的方法和装置。对于本发明的方法，程序员创建一系列纹理贴图。每个纹理贴图近似于距离光点相应距离处的光点的波瓣。每个纹理贴图包括透明纹理信息。这允许光点正确地模拟雾和其他大气条件。一系列纹理贴图被编码在与光点相关联的mipmap中。在使用过程中，模拟环境使用广告牌技术渲染光点。广告牌技术使光点的眼睛朝向眼点。模拟环境动态跟踪从光点到眼点的距离。每次距离变化时，模拟环境都会从mipmap中选择合适的纹理贴图。适当的纹理贴图是正确描绘了眼点和光点之间距离处的光点的纹理图。在不存在适当纹理图的情况下，模拟环境生成内插纹理贴图。然后，仿真环境在渲染光点期间应用所选或生成的纹理贴图。结果是在很宽的距离范围内实际描绘了光点。

摘要： A user's physical location and the time the user is at that location are sampled by an network-enabled mobile computing device at certain intervals, and used to construct a representation of the comparative relevance of the different physical locations where the user lives. This representation is then used then to optimize and prioritize results returned by a local network search operation, informing the user about which search result would be optimal for the user at her intended time for use of that choice.

摘要： A set of specially-configured LUT's are used in a rasterizing portion of a graphics system for simulating Sensor-assisted Perception of Terrain (SaPOT) so that simulation of the image produced by a given sensor can proceed rapidly and with good accuracy at a per-texel level of resolution. More specifically, terrain texels-defining memory is provided with a plurality of addressable texel records where each record contains: (a) one or more material identification fields (MID's); (b) one or more mixture fields (MIX's) for defining mixture proportions for the materials; and (c) slope-defining data for defining a surface slope or normal of the corresponding texel. A sky-map LUT is provided for simulating the act of looking up to the sky along the normal surface vector of a given texel to thereby obtain a reading of the sky's contribution of illumination to that terrain texel. A reflectance LUT is provided for simulating the act of reflecting filtered radiation (light) off the material surface of the given terrain texel to thereby obtain a reading of the amount of light that the surface of the texel will reflect. The reflectance and sky contribution factors are multiplied to obtain a per-texel signal representing the amount sensor-detectable light produced from each terrain texel. A generally similar approach is taken to determine what amount of sensor-detectable, black body radiation will be produced from each terrain texel. Each terrain texel is simulated as having a specifiable mixture of plural surface materials. Each terrain texel is allowed to be shadowed during different times and the per-texel shadowing is accounted for.
