THREE-DIMENSIONAL MODEL DATA PROVIDING PROGRAM, THREE-DIMENSIONAL MODEL DATA PROVIDING SERVER, AND THREE-DIMENSIONAL MODEL DATA TRANSFER METHOD

摘要

PROBLEM TO BE SOLVED: To transfer image data by an appropriate data transfer system, depending on the circumstances.;SOLUTION: When a drawing instruction of a three-dimensional model is outputted by a three-dimensional model creation means 1a, a time for processing, until drawing in each of a command system and a difference picture system is calculated according to the drawing instruction and a data transfer system with shorter time for processing is decided. When the command system has shorter time for processing, data to define a three-dimensional model, following the drawing instruction and data to define a display method of the three-dimensional model are transmitted to a client 2 by a command system transfer means 1c. When the difference image system has shorter time for processing, a two-dimensional projected image is generated from the three-dimensional model, according to the drawing instruction by a difference image system transfer means 1d and the difference image between the generated projected image and the previous projected image is transmitted.;COPYRIGHT: (C)2006,JPO&NCIPI
