THREE-DIMENSIONAL MODEL INFORMATION CREATION DEVICE, INDEX CREATION DEVICE, RETRIEVAL DEVICE, DISTRIBUTION DEVICE AND INFORMATION DISTRIBUTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To set an importance for allowing preferential display of an object important in display on the basis of a view when viewing the object from a plurality of viewpoint positions inside a three-dimensional space to preferentially extract the object necessary for the display according to movement of a viewpoint at high speed.;SOLUTION: This three-dimensional model information production device creates the importance for allowing the preferential display of the object important in the display when displaying a three-dimensional model by use of computer graphics. The three-dimensional model information production device has: a storage part storing the three-dimensional model; and an importance determination part determining the importance set to a polygon of the object on the basis of the view when viewing the object from the plurality of viewpoint positions inside the three-dimensional space, on the basis of the three-dimensional model stored in the storage part.;COPYRIGHT: (C)2005,JPO&NCIPI
