Title:
INFORMATION PRESENTATION DEVICE AND COMPUTER READABLE RECORDING MEDIUM RECORDING INFORMATION PRESENTATION PROGRAM
Document Type and Number:
Japanese Patent JP3275861
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a device for efficiently managing and realizing write operations to an object performed by respective users in an information presentation device for providing a place where the plural users perform communication such as a conference by using a virtual space.
SOLUTION: This device is provided with a 3D layer object storage base 14 for storing the information of a 3D layer object and a 3D layer object management means 12 for generating, integrating and working the 3D layer object or the like. The vertex coordinates and surface structure of the object are duplicated and a special object called the 3D layer object for which a transparent texture image is texture mapping processed on respective surfaces is prepared for the respective users. When write to the texture of the object is performed, by performing the write to the texture of the 3D layer object which is coordinated to the respective users without performing the write to the original object, the revision and correction of the users are realized.
