Apparatus and method for a route instruction service with a three-dimensional model
First Claim
1. A route guidance service method operable in a telecommunications network, where an area serviced by the route guidance service method is represented by a three-dimensional model comprising surface elements corresponding to features visible in the area, the route guidance service method comprising:
- first, creating a description of a route animation by;
defining a route between selected route points, wherein the route and route points lie within the area serviced by the method;
selecting surface elements corresponding to features visible at locations along the route from the three-dimensional model on the basis of the route defined;
forming an ordered set from the selected surface elements by (1) determining an order of appearance of the selected surface elements as the route is traversed, the order of appearance indicating the order in which features corresponding to the surface elements become visible as the route is traversed, and (2) using the order of appearance as a criterion for forming the ordered set, where the description comprises at least in part the ordered set; and
then transmitting the description of the route animation over the telecommunications network to a terminal having a display;
recreating the route animation from the description at the terminal; and
displaying the route animation on the display of the terminal.

Abstract
The invention relates to a method for implementing a route guidance service in a telecommunications system. In order for it to be possible to utilize both the data transmission capacity of the telecommunications system and the memory and processing capacity of the user workstation efficiently in the execution of a route animation based on a three-dimensional model, the description of the 3D model sent to the terminal is restricted by first defining a route between desired route points and thereafter selecting from the 3D model comprising surface elements at least some of the surface elements that are visible to said route. A partial model comprising only these selected surface elements is transmitted to the user workstation, and in addition the requisite description of how the route animation is constructed on the basis of the partial model.

12. A route guidance service system for providing a route guidance service to a user over a telecommunications network, the route guidance service system comprising:
-
a three-dimensional model of an area serviced by the route guidance service system, the three-dimensional model comprised of surface elements representing features visible in the area, a description means for creating a description of a route animation, the description means further comprising;
a route determining means for constructing a route between desired route points, selection means responsive to the route determining means and adapted to select from the three-dimensional model surface elements corresponding to features that become visible as the route is traversed, and a set creation means for creating an ordered set from the selected surface elements on the basis of the route, the set creation means adapted to define for the selected surface elements an order of appearance corresponding to the order of appearance of the surface elements as the route is traversed; and
transmission means for transmitting the description to the user over the telecommunications network. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A computer readable memory medium for storing computer program instructions which, when executed, perform operations for providing a route guidance service over a telecommunications network, the route guidance service servicing an area, wherein the area is represented by a three-dimensional model comprising surface elements corresponding to features visible in the area, the operations comprising:
-
creating a description of a route animation by;
defining a route between selected route points, wherein the route and route points lie within the area;
selecting surface elements corresponding to features visible at locations along the route from the three-dimensional model;
forming an ordered set from the selected surface elements by (1) determining an order of appearance of the selected surface elements as the route is traversed, the order of appearance indicating the order in which features corresponding to the surface elements become visible as the route is traversed, and (2) using the order of appearance as a criterion for forming the ordered set, where the description comprises at least in part the ordered set; and
thentransmitting the description of the route animation over the telecommunications network to a terminal having a display. - View Dependent Claims (20)
