Efficient recreation of the past objects and visual simulation


Figure 8 shows the modified result, and diameters
of stone columns are modified in this figure.




Figure 9 shows the recreated Palatitsa Palace by 3D Modeling System.





Evaluation of Modelling System
In order to evaluate the 3D Modeling System, the Palatitsa Palace was recreated by manual. 6 hours were needed for construction of basic 3D parts, but it took 4 hours for placement in manual case, and it took 20 minutes in auto placement (Figure 10). As an additional function for the efficient modeling method which developed in this paper, visual simulation can be achieved using 3D CG. By the way, utilization of Internet and VR techniques to facilitate promotion of cultural heritage is one of the terms reference of ISPRS WG V/4 (Image analysis and spatial information systems for applications in cultural heritage). For this goal, the visual simulation is opened at following web site: http://www.chikatsu-lab.g.dendai.ac.jp/wgv4/




Conclusion

3D Modeling System for recreating historical monuments was described in this paper, and the remarkable points of this system are as follows:
  • Attribute data of the basic parts can be acquired easily on the planimetric map.
  • The parts can be placed automatically according to the attribute data.
  • Efficient modification of the parts can be preformed.
  • Reducing time and labor can be achieved.
  • Promotion of cultural heritage is expected by visual simulation through internet.
It is concluded from recreating the Palatitsa Palace that the 3D modeling system is expected to become a useful system not only lost objects but exist objects. There are issues, however, for further work. These problems include more efficient acquisition of the attribute data, and increase the kind of the basic parts so that the system be applicable to various objects.
