ウォークスルーシステムによる歩行経路に沿った視野空間分析ツールの開発と適用

抄録

In this paper, we develop a new tool for analyzing visual space along moving paths. Our analyzing method is based on the isovist theory which is known as one of the methods for describing visible space. In addition, our tool generates visual field data using a walk-through system. To calculate the visual field, our method uses z-buffer data that is three-dimensional graphics data for hidden surface removal. We apply this system to a real building for evaluation the applicability. As a result of analyzing the changes of visual field with the four walk-through paths in the Villa Savoye 3D model, the changing trends of the descriptive indicators were observed when columns, walls, the slope and openings come into the sight or disappear from the sight.
