This paper explores a method for creating large-scale urban 3D models using Historical GIS data. The method is capable of automatically generating realistic VR models based on GIS data at a low cost. 3D models of houses are created from polygon data, fences from line data, and pedestrians and trees from point data. The method is applied to the Virtual Kyoto(More)
Using the recently developed 3D GIS (Geographic Information System) and related visualisation technologies, we have created a digital diorama of an entire historical city, which can be used to virtually travel through different realistic landscapes at different times in the history. The digital diorama called Virtual Kyoto is the virtual geographic(More)
In recent years, application of virtual-reality technology to simulate historical architectures is becoming popular. The biggest advantage of the virtual-reality technology is man-machine interaction. However, the man-machine interaction requires high computing costs to realize simultaneous execution of processing user commands and rendering a 3D scene.(More)
This paper explores a method for creating large-scale urban 3D models from GIS spatial data. It is capable of automatic generation of realistic VR models based on existing GIS data. Parametric 3D models of houses are created from polygon data, fences from line data, and pedestrians and trees from point data. The method is applied to the project(More)
In this paper, I propose a new methodology for analysing landscape drawing methods using a GIS. The subject of my analysis is the genre of Japanese screen paintings known as rakuchū rakugai zu, created between the 16th and 18th centuries. Rakuchū rakugai zu provide bird’s-eye views of the then-capital city of Kyoto, including buildings, natural features,(More)
This paper explores a method for reconstructing large-scale 3D urban areas from 2D data of the Geographic Information System (GIS). Our approach enables automatic reconstruction of 3D models of houses using the GIS data. The main target of the automatic generation of 3D models is the city of Kyoto in the Edo era and the houses peculiar to the urban area of(More)
