Objectives To create content that can be shown to the
general public to improve their understanding of architectural research
To develop a system for architectural design proposals and to put these digital archives
to practical use
To develop a system that many users can easily use via the Internet
WSCG'2007, Plzen, Czech Republic
Concept
Examination of architectural design proposal based on comparison
Comparison effectively improves understanding Consideration of differences reveals and clarifies
contents Comparison of different contents clarifies
relationships, effects, and causal relations

1. Database
3D objects(3D model data, GIS data)
2D contents(Photo, Texture, and Text)
Data converted using modeler.Scenes formed by grouping models.
Attributes/behaviors assigned to objects(camera, light, collision detection, LOD, gravity, etc.)
3D objects exported tonavigation system
5.Data block and scene Saving
Data gathered from modeling.
