Method for synthesizing image of object in three-dimensional scene in video terminal that is utilized for playing on-line video games, involves constructing image from co-ordinates, observation point and field limit, and displaying image

摘要

The method involves defining a portion of an occupied space. A space around the space portion is divided into free space portions based on vertices of the occupied space portion, and coordinates of faces of the space portion are stored in a database that is queried for an identified observation point. One of the free space portions containing the point is selected (D). The co-ordinates of one of the faces corresponding to the free space portion are output. An image is constructed (F) from the output co-ordinates, the observation point and a field limit of the image. The image is displayed (G). Independent claims are also included for the following: (1) an image data management unit for providing visual data (2) a video terminal comprising a request receiving unit (3) a computer program product comprising a set of instructions for executing a method for synthesizing an image.
