A map database stores three-dimensional polygons of features, as well as water system polygons such as sea and lake and ground surface polygons. The map database stores map data in multiple levels having different levels of details, such as levels LVa to LVc. A procedure of displaying a three-dimensional map offsets the water systems relative to the ground surfaces, draws a map of a distant view area distant away from the viewpoint using map data at a low level of details, subsequently clears a depth buffer and newly draws a map of a close view area close to the viewpoint using map data at a high level of details. The offset is set to increase in the distant view area and decrease in the close view area. Increasing the offset in the distant view area avoids the occurrence of Z-fighting in the distant area from the viewpoint.

A system includes a two dimensional display device coupled to control circuitry. The control circuitry establishes a two dimensional representation of at least first and second floors of a building. Responsive to a selected input closed boundaries are established which surround the two dimensional representations of each floor. Responsive to at least one other input, first and second coordinate systems are established with one coordinate system associated with each boundary. Three dimensional information can be established relative to the various devices installed on each floor, and, simulations of operation can be carried out. An installer can move various of the devices and re-run the simulation to evaluate which configuration provides a better communication result.

[Problem] To provide a map in which overlapping characters and the like are easily distinguished. [solution] A terminal (300) is prepared which is provided with a display capable of stereoscopic viewing by visually recognizing each of a right-eye-use image and a left-eye-use image using the right eye and the left eye, respectively. Map data (211) to be a background is generated as common image data for all areas by performing parallel projection of a 3-dimensional model stored in a 3D map database (104). At this time, by setting projection conditions which impart a parallax between the right-eye-use and left-eye-use images, it is possible to prepare right-eye-use/left-eye-use parallel projection data for all areas. With regard to characters displayed upon a map, when performing display, display depth is set on the basis of such conditions as overlapping that passes through characters, and in accordance with the same, display positions of the characters are offset to generate stereoscopic-use image data. As a result, even overlapping characters are displayed at different display depths, and therefore, it is possible to relatively easily distinguish therebetween.

A user interface for rotating imagery among a plurality of canonical views of a geographic area of interest is disclosed. The interface includes at least one rotation control icon for rotating the imagery among a plurality of canonical views of the geographic area, and a direction indicating portion that indicates a compass direction associated with the canonical view presented on the display device. In particular implementations, the interface can be configured to come into view over the imagery whenever a user navigates to a particular view of the imagery where a plurality of canonical views is available. The motion of the navigation control interface appearing into the imagery is intended to draw attention to the control interface to inform the user that additional canonical views are available.
摘要:
An electronic device displays on a display a first three-dimensional map view of a respective map location. The first three-dimensional map view is viewed from a first angle while an orientation of the electronic device corresponds to a first orientation. The electronic device detects a rotation of the electronic device with at least one orientation sensor, and determines a respective orientation of the electronic device. The respective orientation is distinct from the first orientation. While detecting the rotation of the electronic device, the electronic device updates the first three-dimensional map view with a respective three-dimensional map view of the respective map location. The respective three-dimensional map view is viewed from a respective angle distinct from the first angle. The respective angle is determined in accordance with the respective orientation of the electronic device.

Ausführungsbeispiele beziehen sich auf eine Ansteuereinrichtung (1) zum Markieren einer Mehrzahl möglicher Ziele (30, 23, 33, 72) in einem Kartenausschnitt (31) auf einer Anzeigefläche (3). Die Ansteuereinrichtung (1) umfasst eine Eingangseinrichtung (4). Diese ist ausgebildet, um ein Kategorieauswahlsignal (35) zu empfangen. Das Kategorieauswahlsignal (35) korrespondiert zu einer Auswahl eines Benutzers. Ferner umfasst das Kategorieauswahlsignal (35) eine Information über eine gewählte Kategorie möglicher Primärziele (32). Die Ansteuereinrichtung (1) umfasst auch einen Controller (6). Dieser ist ausgebildet, um ansprechend auf das Kategorieauswahlsignal ein Anzeigesignal (37) zu erzeugen. Das Anzeigesignal (37) bewirkt eine Wiedergabe möglicher Primärziele (32) in dem Kartenausschnitt (31). Das Anzeigesignal (37) korrespondiert zu der Information der gewählten Kategorie. Ferner bewirkt das Anzeigesignal auch eine Wiedergabe von Sekundärzielen (33) zumindest einer anderen Kategorie in dem Kartenausschnitt (31), wobei sich die Darstellung der Primärziele (32) der gewählten Kategorie von der Darstellung der Sekundärziele (33) der anderen Kategorie unterscheidet.
