    • [Problem] In the case of displaying each feature along with a character string representing information with regard to the feature on a three-dimensional map, an object is to facilitate understanding of the relationship between the feature and the character string without reducing the reality of the three-dimensional map. [Solution to Problem] A terminal 10 includes: a transmitter/ receiver 12 that obtains map data 22 used to display each feature three-dimensionally, representative point position data representing position of a two-dimensional representative point of the feature and character data 26 used to display information with regard to the feature from a map database 20; a feature image generator 14 that generates a feature image in which each feature is drawn three-dimensionally; and a character display controller 16 that controls display of a character string representing information with regard to the feature on the feature image. The character display controller 16 displays the character string above the feature on the feature image, and displays a shadow image representing a shadow of the character string at a position related to the representative point on an upper surface of the feature, based on the representative point position data 24.

    • Some embodiments provide a mapping application for generating views of a three-dimensional (3D) map. The mapping application includes a geographic data module for identifying 3D map data for a portion of a 3D map. The 3D map data includes (1) camera captured images (CCIs) of a portion of the real world that the portion of the 3D map represents, (2) a first set of map elements in the portion of the 3D map specified to be textured with CCIs, and (3) a second set of map elements in the portion of the 3D map specified to be textured with non-CCIs. The mapping application also includes a rendering engine for rendering a view of the 3D map by generating effects for several map elements in the 3D map in order to make the several map elements seem animated in the view of the 3D map.

    • Some embodiments provide a non-transitory machine -readable medium that stores a mapping application which when executed on a device by at least one processing unit renders views of a three-dimensional (3D) map. The mapping application requests a first set of map tiles associated with a portion of the 3D map. In response to the request, the mapping application receives a second set of map tiles that does not include all the tiles in the first set of map tiles. For at least one tile in the first set of map tiles but not in the second set of map tiles, the mapping application generates a replacement map tile that includes geospatial data. The mapping application further renders the portion of the 3D map based on the second set of map tiles and the replacement map tile.

    • A mobile device uses vision and orientation sensor data jointly for six degree of freedom localization, e.g., in wide-area environments. An image or video stream is captured while receiving geographic orientation data and may be used to generate a panoramic cylindrical map of an environment. A bin of model features stored in a database is accessed based on the geographic orientation data. The model features are from a pre-generated reconstruction of the environment produced from extracted features from a plurality of images of the environment. The reconstruction is registered to a global orientation and the model features are stored in bins based on similar geographic orientations. Features from the panoramic cylindrical map are matched to model features in the bin to produce a set of corresponding features, which are used to determine a position and an orientation of the camera.

    • Systems and methods for providing smooth level of detail transitions for geometric objects, such as geometric terrain tiles, are provided. In one embodiment, a parent geometric tile associated with a first level of detail can be partitioned into sub-tiles. The sub-tiles can be blended independently with child geometric tiles associated with a second level of detail. The blends can be adjusted as a function of camera distance over a transition range to provide a smooth level of detail transition. Various enhancements and modifications can be made to the level of detail transition, such as implementing a bias in the level of detail calculation, implementing an unpop algorithm over only a subset of the transition range, implementing a time based fade during a camera stop, and other enhancements.
    • 提供了用于为几何对象(例如几何地形图块)提供平滑级别的细节过渡的系统和方法。 在一个实施例中,与第一细节级相关联的父几何瓦片可以被划分成子瓦片。 子瓦可以独立地与与第二级细节相关联的儿童几何瓦片混合。 混合物可以根据相机在过渡范围内的距离进行调节,以提供平滑的细节过渡。 可以对细节过渡的级别进行各种增强和修改,例如在细节计算水平上实现偏差,仅在过渡范围的一个子集上实现unpop算法,在相机停止期间实现基于时间的渐变,以及 其他增强功能。
