3D model data management system, model delivery server, 3D service server, 3D model data management method, model distribution server program, and 3D service server program

摘要

Problem to be solved: to provide a 3D modeling data management system capable of confirming whether or not modification has been made in a region permitted to be changed in 3D model data.A model delivery server for storing 3D model data described by a predetermined code capable of setting a change permitting areaA 3D service server that delivers 3D service by downloading 3D model data from a model delivery server according to a delivery requestModel delivery serverA model modification confirmation unit that rejects the upload request when the hash value which is calculated based on the code excluding the change permitting area and the hash value of the 3D model data are disagreement are provided.3D service serverThe model has a model validity check unit to refuse the delivery of the 3D service when the hash value calculated by the 3D model data and the hash value calculated based on the code excluding the change permitting area are disagreement.Diagram
