Document Type and Number:
Japanese Patent JP3549775
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide the device and method by which an operator can record the appreciation information of an object arranged in a three-dimensional space generated by a computer and can impart the information to other users. SOLUTION: When an operator transmits a recommended vector generation instruction 111 through an operation inputting device and an operation managing means 11, a system parameter obtaining means 14 obtains system parameter information 140, an appreciating direction deciding means 15 decides an object appreciation direction by obtaining an object rotation information and a sight line direction, an appreciation central point deciding means 16 decides the central point of appreciation by using an object rotation and movement information, a view point direction, a sight line direction and the shape data from an object shape DB, an appreciation weight deciding means 17 decides an appreciation weight based on a system parameter in formation, an appreciation central point information and an object shape information, an appreciation attitude deciding means 18 decides the appreciation attitude based on a sight line direction information, and a recommended vector generating means 19 generates the recommended vector based on an appreciation direction, the central point of appreciation, the appreciation attitude and appreciation weight and stores it in a recommendation vector DB 20.
