- Knowledge management for 3D CG models -


To build an intensive wide knowledge that is complementary to each individuals, and to create innovations by using the knowledge, it is more important than ever that users efficiently share their knowledge regarding to a three-dimensional (3D) geometrical model data and related information.

A solution by using our knowledge management for 3D computer graphics (CG) models enables the user to search and retrieve several geometrical models that are similar to a specified key model from a database, and to detect the area where there are geometrically some differences between the models. Additionally, it is possible for users to synchronously share and communicate the geometrical model with the interaction during an online meeting, and to store the interaction data in the database for later reference. The cycle to store, search, retrieve, detect, share, examine, and store the model and related data is an accumulation of the knowledge in a company about the 3D geometrical model. (Figure 1)

This solution is based on two technologies by Tokyo Research Laboratory, those are, 3D geometry search and analysis technology, and synchronous/asynchronous 3D collaboration technology.

Applications include, especially in the manufacturing area, a data management system to search and compare part's data at each design, development, and production phase, or a call center support system to collaborate using a shared model and its behavior at a maintenance phase. (Figure 2)
